This box plot shows the distribution of wind speeds measured near an oil rig.Work out the value that completes the statement below.
50% of the speeds are between 36 km/h and… km/h

Answers

Answer 1

The value that completes the box plot distribution of wind speed statement is 48 km/h.

How to calculate the second speed?

To determine the value that completes the statement, locate the median, which represents the 50th percentile. From the plot, the median (50th percentile) is at approximately 42 km/h.

The box extends from the first quartile (25th percentile) to the third quartile (75th percentile), so determine the range of speeds that contains 50% of the measurements by finding the difference between the median and the first quartile, and then adding it to the median.

The plot estimates that the difference between the median and the first quartile is approximately 6 km/h. Therefore, 50% of the speeds are between 36 km/h and (42 + 6) km/h, which simplifies to 36 km/h and 48 km/h.

So the value that completes the statement is 48 km/h.

If q1=1.6*10^ -19 C and q2=3.2*10^ -19 C and the distance between the charges is 2cm. What is the force between the charges?

Show work please. Giving out brainliest.

Answers

Hey there!

Answer:

first question= approximately 6.8 cm

second question=approximately 2.88 x 10^-28 N

Explanation:

To determine the separation distance between the charges, we can use Coulomb's law, which states that the force between two point charges is given by:

F = k * q1 * q2 / r^2

where F is the force, k is Coulomb's constant (9 x 10^9 N m^2/C^2), q1 and q2 are the magnitudes of the charges, and r is the separation distance between the charges.

In this case, we have q1 = 5.0 x 10^-6 C, q2 = -6.0 x 10^-6 C, and F = -0.72 N. Plugging in these values and solving for r, we get:

-0.72 N = (9 x 10^9 N m^2/C^2) * (5.0 x 10^-6 C) * (-6.0 x 10^-6 C) / r^2

Solving for r, we get:

r = sqrt[(9 x 10^9 N m^2/C^2) * (5.0 x 10^-6 C) * (-6.0 x 10^-6 C) / (-0.72 N)]

r ≈ 0.068 m or 6.8 cm

Therefore, the separation distance between the charges is approximately 6.8 cm.

For the second question, we can use the same formula, Coulomb's law, to find the force between the charges:

F = k * q1 * q2 / r^2

Plugging in the values, we get:

F = (9 x 10^9 N m^2/C^2) * (1.6 x 10^-19 C) * (3.2 x 10^-19 C) / (0.02 m)^2

F ≈ 2.88 x 10^-28 N

Therefore, the force between the charges is approximately 2.88 x 10^-28 N.

What is the lowest frequency of light

Answers

The lowest frequency of light that can exist is zero hertz (Hz), which is also known as direct current (DC).

This is because light is a type of electromagnetic radiation that consists of oscillating electric and magnetic fields. These fields oscillate at a certain frequency, and the frequency determines the energy and properties of the light.

However, in the absence of any oscillation, there is no frequency and hence no light. In other words, the lowest frequency of light is no light at all.

It's worth noting that there are other forms of electromagnetic radiation that have frequencies lower than visible light, such as radio waves and microwaves. These types of radiation have frequencies that range from about 3 kilohertz (kHz) to several gigahertz (GHz).

Two similar spheres A and B, have charges of +2 * 10 ^ -6 * C and + 1 * 10 ^ -6* C The of the electrostatic force on A due to B is 2.4 Newtons. What is the magnitude of electrostatic force on B due to A. Why ?

Show work please and explain.

Answers

The magnitude of the electrostatic force on sphere B due to sphere A is also 2.4 N, because the forces are equal in magnitude but opposite in direction as they form an action-reaction pair.

How to find the magnitude of electrostatic force on B due to A?

First by Coulomb's Law, the electrostatic force F between two point charges Q1 and Q2, separated by a distance r, is given by

F = k * (Q1 * Q2) / r^2

Where k is the Coulomb constant, which has a value of 9 × 10^9 N·m^2/C^2.

In this case, we have two spheres A and B, with charges +2 * 10^-6 C and +1 * 10^-6 C, respectively. The electrostatic force on A due to B is given as 2.4 N.

To find the electrostatic force on B due to A, we can use Coulomb's Law and the fact that the force between the two spheres is an action-reaction pair, meaning that the forces on A and B are equal in magnitude but opposite in direction. Therefore, the magnitude of the electrostatic force on B due to A is also 2.4 N.

We can see this by rearranging Coulomb's Law as:

F = k * (Q1 * Q2) / r^2

=> Q2 = (F * r^2) / (k * Q1)

where

Q2 is the charge on sphere B, R is the distance between the two spheres, and we have used the known force and charge on sphere A.

Substituting the values given, we get:

Q2 = (2.4 N * (1 m)^2) / (9 × 10^9 N·m^2/C^2 * 2 × 10^-6 C) = 0.133 C

Therefore, the magnitude of the electrostatic force on sphere B due to sphere A is also 2.4 N, because the forces are equal in magnitude but opposite in direction as they form an action-reaction pair.

a satellite at a particular point along an elliptical orbit has a gravitational potential energy of 5200 mj with respect to earth's surface and a kinetic energy of 4100 mj . later in its orbit the satellite's potential energy is 5600 mj . part a use conservation of energy to find its kinetic energy at that point. express your answer to two significant figures and include the appropriate units.

Answers

So the answer with two significant figures and appropriate units is Kinetic energy at second point is 3.7 x 10^6 J or 3.7 MJ.

What is kinetic energy?

Kinetic energy is a form of energy that an object possesses by virtue of its motion. It is defined as the energy that an object has due to its mass and velocity. The formula shows that the kinetic energy of an object increases as its mass and velocity increase. For example, a heavy truck traveling at a high speed has a higher kinetic energy than a small car traveling at the same speed. The concept of kinetic energy is important in physics, as it is used to explain many phenomena, such as collisions, projectile motion, and the behavior of waves. It is also useful in engineering and other fields, as it helps to quantify the energy required for different types of motion, such as in machines or vehicles.

Here,

According to the law of conservation of energy, the total mechanical energy of a system remains constant if there are no external forces acting on the system. In the case of a satellite in an elliptical orbit around the Earth, the total mechanical energy is the sum of its kinetic energy and gravitational potential energy.

We can use this principle to solve for the kinetic energy of the satellite when its potential energy is 5600 MJ. We know that the total mechanical energy is conserved, so:

Total mechanical energy at first point = Total mechanical energy at second point

(KE + PE)1 = (KE + PE)2

Substituting the given values:

4100 MJ + 5200 MJ = KE2 + 5600 MJ

Simplifying:

KE2 = (4100 MJ + 5200 MJ - 5600 MJ)

KE2 = 3700 MJ

Therefore, the kinetic energy of the satellite at the second point is 3700 MJ. It's important to note that the units for energy are Joules (J), and mega-Joules (MJ) are equal to 1,000,000 Joules.

An insulating sphere of radius a, centered at the origin, has a uniform volume charge density rho. Find the electric field E(→r) inside the sphere (for r

Answers

The electric field E(→r) inside the sphere is: E(→r) = (ρ × r) / (3ε₀), where ρ is the uniform volume charge density, r is the distance from the origin, and ε₀ is the electric constant.

To find the electric field E(→r) inside the sphere with a uniform volume charge density ρ, we can use Gauss's law.

First, we choose a spherical Gaussian surface of radius r < a, centered at the origin. The electric field is radial and has the same magnitude at every point on the surface due to the symmetry of the charge distribution.

By Gauss's law, the electric flux through the surface is given by:

Φ_E = E(→r) × 4πr²

where Φ_E is the electric flux through the surface and E(→r) is the electric field at every point on the surface.

The total charge enclosed by the surface is given by:

Q_enc = (4/3) × πr³ × ρ

where Q_enc is the total charge enclosed by the surface and ρ is the charge density.

By Gauss's law, the electric flux through the surface is also related to the total enclosed charge by:

Φ_E = Q_enc / ε₀

where ε_0 is the electric constant.

Combining these equations, we have:

E(→r) × 4πr² = (4/3) × πr³ ρ / ε_0

Solving for E(→r), we get:

E(→r) = (ρ × r) / (3ε₀)

Therefore, the electric field E(→r) inside the sphere is directly proportional to the distance from the origin and the charge density, and is independent of the choice of direction.

To determine the x-direction component of each vector, we need to use trigonometry. We can use the cosine function to find the x-component of each vector since cosine gives the adjacent side length of a right triangle.

For vector A:

The length of the adjacent side (x-component) is given by: cos(15°) = 0.9659

a. a 5-kg object orbiting Earth halfway to the moon (1,681 m/s).

b. a 10-kg object orbiting Earth just above Earth's surface (7,905 m/s).

The circular velocity of an object in orbit depends on its mass, the mass of the central body, and the distance between them. The formula for the circular velocity is V = sqrt(GM/R), where G is the gravitational constant, M is the mass of the central body, and R is the distance between the two objects.

a. The distance between the 5-kg object and Earth is halfway to the Moon, which is about 384,400 km. Therefore, the distance between the object and Earth is 384,400/2 = 192,200 km.

Answers

The velocity of the other pool ball is (3, -1) m/s.

How solve this problem?

We can solve this problem using the principle of conservation of momentum, which states that the total momentum of a system remains constant if no external forces act on it.

Let the initial velocity of the stationary pool bar be (0,0) m/s. The initial momentum of the system is:

p_initial = m1 * v1 + m2 * v2

where m1 and m2 are the masses of the pool balls, and v1 and v2 are their initial velocities.

Substituting the given values, we have:

p_initial = 0.1 kg * (5, -4) m/s + 0.1 kg * (0,0) m/s

= (0.5, -0.4) kg m/s

After the collision, the total momentum of the system is still conserved, but now we have one ball at rest and the other moving with a velocity of (2, -3) m/s. Let the velocity of the other pool ball be (vx, vy) m/s. Then we have:

p_final = m1 * (2, -3) m/s + m2 * (vx, vy) m/s

where m1 and m2 are still the masses of the pool balls.

Setting the initial and final momenta equal and solving for (vx, vy), we get:

p_initial = p_final

0.5, -0.4 = 0.1 * (2, -3) + 0.1 * (vx, vy)

0.5, -0.4 = (0.2, -0.3) + (0.1vx, 0.1vy)

0.5 - 0.2 = 0.1vx

-0.4 + 0.3 = 0.1vy

vx = 3 m/s

vy = -1 m/s

Therefore, the velocity of the other pool ball is (3, -1) m/s.

Answers

The larger piston can exert about 9.69 times more force than the force applied to the smaller piston.

What is the force exerted by piston?

Force exerted by a piston is directly proportional to pressure applied and the surface area of piston. Since the hydraulic system is connected, pressure is same in both vessels.

Surface area of small piston is:

A_small = πr_small² = π(0.9 cm)² ≈ 2.54 cm²

Surface area of the large piston is:

A_large = πr_large² = π(2.8 cm)² ≈ 24.62 cm²

Force exerted by small piston is:

F_small = P × A_small

P is pressure and A_small is surface area of small piston.

Force exerted by large piston is:

F_large = P × A_large

P is pressure and A_large is the surface area of large piston.

F_large/F_small = (P × A_large)/(P × A_small) = A_large/A_small

F_large/F_small = 24.62 cm² / 2.54 cm² ≈ 9.69

To convert 25 degrees Celsius (°C) to Kelvin (K), you can use the following formula:

0°C + 273.15 = 273.15K

Plugging in the given value of 25 °C, we get:

K = 25 + 273.15 = 298.15 K

Therefore, 25 °C is equivalent to 298.15 K.

The Kelvin (K) scale is an absolute temperature scale where 0 K represents absolute zero, the theoretical temperature at which all matter would have zero thermal energy. On the Kelvin scale, the size of one degree is the same as that of one Celsius degree, but the Kelvin scale starts at absolute zero, while the Celsius scale starts at the freezing point of water.

To convert a temperature from Celsius to Kelvin, you simply need to add 273.15 to the Celsius temperature. This is because the size of one Kelvin degree is the same as one Celsius degree, but the Kelvin scale starts at absolute zero (which is -273.15 °C), so adding 273.15 to a temperature in Celsius converts it to Kelvin.

What is the conversion of 99.3 f to c ?

Answers

99.3°F is equivalent to 37.4°C

A temperature unit developed from the SI (International System of Units) is Celsius (symbol: °C).

Prior to the adoption of the metric system, Fahrenheit (symbol: °F) was a commonly used measurement of temperature.

To convert Fahrenheit (°F) to Celsius (°C) we have to first subtract 32 from Fahrenheit and then multiply it by .5556 or 5/9.

We have to convert 99.3 degrees Fahrenheit (°F) to Celsius (°C),

We can use the following formula:

°C = (°F - 32) x 5/9

As per the given information,

°F = 99.3

Substituting the value 99.3 for °F, we get:

°C = (99.3 - 32) x 5/9

= 67.3 x 5/9

= 37.4

Therefore, 99.3°F is equivalent to 37.4°C.

A soccer ball has mass when full of air of 0.45 kg. If a goalkeeper kicks this ball,
the ball will leave their foot with a velocity of 33 m/s. This kick usually occurs
when the goalkeeper's foot is 0.8 m above the ground. If another player "traps"
the ball using their chest, which is an average of 1.4 m above the ground, how fast
is that soccer ball moving right before it hits the chest of the player? [Ignore
Friction]

Answers

The soccer ball is moving at a speed of approximately 10.84 m/s just before it hits the player's chest.

What is the conservation of energy?

The conservation of energy means that there is not any loss of energy but energy changes from one form to another.

To solve this problem, we can use the principle of conservation of energy, which states that the total energy in a system is conserved. In this case, we can assume that the system consists of only the soccer ball.

The initial energy of the soccer ball is given by its kinetic energy:

KE₁= 0.5 x m  x  v₁²

Where m is the mass of the soccer ball and v₁ is its velocity just after being kicked by the goalkeeper.

The final energy of the soccer ball just before it hits the player's chest is given by its potential energy and kinetic energy:

KE₂ + PE₂= m x  g x h₂ + 0.5 x m x v₂²

Where h₂ is the height of the player's chest above the ground, g is the acceleration due to gravity (9.81 m/s²), and v₂is the velocity of the soccer ball just before it hits the player's chest.

Since energy is conserved, we can equate the initial energy to the final energy:

KE₁ = KE₂ + PE₂

Substituting the expressions for KE₁and KE₂+ PE₂, we get:

(0.5 x m x v₁²) = (m x g x h₂) + (0.5 x m x v₂²)

Simplifying and solving for v2, we get:

v₂ = √(v₁² - 2 x g x (h₂ - 0.8))

Substituting the given values, we get:

v₂ = √((33 m/s)² - (2 x 9.81 m/s²) x (1.4 m - 0.8 m))

v₂= 10.84 m/s

Therefore, the speed of the soccer ball will be 10.84 m/s just before it hits the player's chest.

A king’s crown, presumed to be pure gold, has a mass of 1.00 kg. When submerged in water its apparent mass is measured to be 0.92 kg. Is the crown made of pure gold (p = 19.3 kg/liter)?

Answers

The crown is not made up of pure gold as its density which is calculated is observed to be less than that of the pure gold.

The formula for an object's density is ρ = m/v.

where,

m is mass

v is volume

Mass of the crown is given as 1 kg.

When submerged in water, its mass becomes 0.92 kg.

So, volume of water displaced is 0.08 L.

Density of pure gold is given as, ρ gold = 19.3 kg/L

The amount of water that is displaced has the same volume as the crown. Let us calculate the density of crown,

ρ crown = m/v = 1/0.08 = 12.5 kg/L

Comparing the above obtained value with the density of pure gold we have, ρ crown < ρ gold.

Thus, the crown is not made up of pure gold.

According to general relativity, earth goes around the sun rather than flying straight off into space because___

Answers

According to general relativity, Earth goes around the sun rather than flying straight off into space because of the curvature of spacetime caused by the mass of the sun.

The general theory of relativity explains how gravity is actually caused by the curvature of spacetime and not by any actual force at all. The mass of the sun bends spacetime, which in the case of the Earth orbiting the sun causes the Earth to move on a curved orbit. The orbit of the Earth is visible as a curving path.

The Earth would indeed continue to move in a straight line if it weren't for the sun's mass's effect on the curvature of spacetime. But, general relativity offers a more thorough understanding of gravity and demonstrates that the Earth's and other solar system objects' motions are caused by the curvature of spacetime.
