is silicon a better conductor of electricity than sulfur

Answers

Yes, silicon a better conductor of electricity than sulfur. The reasons are explained below.

Due to the outer electrons of pure silicon and germanium being bound in the covalent bonds of the diamond-like framework, these materials are weak electrical conductors.

Through the movement of free electrons, silicon can transmit electricity. Since silicon is an n-type semiconductor, just a small amount of n-type contaminants will produce free electrons. The current that moves through silicon from one place to another is caused by these free electrons.

Pure sulphur is a tasteless, odourless, brittle solid with a pale golden colour that is insoluble in water and a weak conductor of electricity. Sulfur meets three of the basic criteria for non-metals, making it a non-metal. Due to the restriction on the unrestricted movement of electrons, it is a poor conductor of heat and electricity. To undergo ionisation, an element's electrons need space to travel around and generate an electric charge.

A pool ball of mass 100 g and velocity (5, -4) m/s collides with a stationary pool bar of the same mass. After the collision, one of the pool balls has a velocity (2, -3) m/s. Find the velocity of the other pool ball.​

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.

Suppose the electric force between two charged objects is 85 N. If each object had 0. 6 times as much charge, what would be the electric force between them?

Answers

The electric force between the two charged objects, if they were 0.6 times more charged, would be 30.6 N.

According to Coulomb's Law, the electric force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. The equation for Coulomb's Law is: F = kQ₁Q₂/r² where:

F is the electric force, k is the Coulomb constant, Q₁ and Q₂ are the charges of the objectsr is the distance between them.

In this case, if each object had 0.6 times as much charge, the electric force between them would be:

F' = k(0.6Q₁)(0.6Q₂)/r² =

F' = (0.6)(0.6)kQ₁Q₂/r²

F' = 0.36kQ₁Q₂/r² ´

F' = 0.36F

Therefore, the electric force between the two charged objects would be 0.36 times the original force, or 0.36(85 N) = 30.6 N. So, the electric force between the two charged objects would be 30.6 N.

The electric force between them would be 30.6 N.

The electric force between two charged objects can be calculated using Coulomb's Law:
F = kq1q2 / r^2

Where F is the electric force, k is Coulomb's constant (8.99 x 10^9 Nm^2/C^2), q1 and q2 are the charges on the objects, and r is the distance between them.

If each object had 0.6 times as much charge, then the new charges would be:
q1' = 0.6q1
q2' = 0.6q2

Substituting these values into Coulomb's Law gives us:
F' = k(0.6q1)(0.6q2) / r^2
F' = (0.6)^2 * kq1q2 / r^2
F' = 0.36 * F

So the new electric force would be 0.36 times the original electric force:
F' = 0.36 * 85 N
F' = 30.6 N

Therefore, if each object had 0.6 times as much charge, the electric force between them would be 30.6 N.

how to convert 25 c to k?

Answers

25 °C is equivalent to 298.15 K. The formula to convert Celsius (°C) to Kelvin (K) is 0°C + 273.15 = 273.15K.

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.

The Kelvin scale is used in many scientific fields, especially in physics and chemistry, where absolute zero is a critical reference point. It is also used in engineering and technology, particularly in the fields of thermal engineering and materials science

suppose you are driving a 500-kg zamboni when it suddenly breaks down, forcing you to get out and push. you apply a force of 85 n on the machine, which experiences a constant frictional force of 5 n. how long (in seconds) will it take to push the zamboni the remaining 40 m?

Answers

The net force acting on the Zamboni is:

F_net = F_applied - F_friction

where F_applied is the force you apply, and F_friction is the frictional force. Substituting the given values, we get:

F_net = 85 N - 5 N = 80 N

The acceleration of the Zamboni is given by:

a = F_net / m

where m is the mass of the Zamboni. Substituting the given values, we get:

a = 80 N / 500 kg = 0.16 m/s^2

The distance the Zamboni moves is given by:

d = 40 m

The equation for motion with constant acceleration is:

d = 1/2 * a * t^2

where t is the time taken to move the distance d. Rearranging this equation, we get:

t = sqrt(2 * d / a)

Substituting the given values, we get:

t = sqrt(2 * 40 m / 0.16 m/s^2) = 10 s

Therefore, it will take 10 seconds to push the Zamboni the remaining 40 meters.

A stone is dropped from the top of a tall building and at the same time another stone is thrown vertically upwards from the ground level with a velocity of 20m/s. The stones meet at exactly 5s after their release. Calculate the height of the building? (g=10m/s²)​

Answers

The height of the building is 42.4 meters.

What is  the height of the building?

Let's call the height of the building "h". We can use the following kinematic equations to solve for "h":

For the stone that is dropped from the top of the building:

h = (1/2)gt² (Equation 1)

For the stone that is thrown upwards from the ground:

y = vt - (1/2)gt² (Equation 2)

where;

y is the distance travelled by the stone upwards from the ground andv is the initial velocity of the stone (which is 20 m/s in this case).

We know that the two stones meet at exactly 5s after their release. This means that the distance travelled by the stone thrown upwards from the ground is equal to the height of the building, i.e.,

y = h

We can substitute this equation into Equation 2 and rearrange it to solve for "t":

h = vt - (1/2)gt²

h = 20t - (1/2)gt²

t = (2h/g - 20)/(-1) (Equation 3)

Now we can substitute Equation 3 into Equation 1 and solve for "h":

h = (1/2)g((2h/g - 20)/(-1))²

h = (1/2)g(2h/g - 20)²

h = (1/2)g(4h²/g² - 80h/g + 400)

Simplifying this equation by multiplying everything by 2g and moving all the terms to one side, we get:

4h² - 160h - 400 = 0

Solving this quadratic equation using the quadratic formula, we get:

h = (160 ± sqrt(160² + 4(4)(400))) / (2(4))

h = (160 ± sqrt(32,000)) / 8

We can ignore the negative solution, so:

The vector A carries you 222.487 units to the right, vector B carries you 86.424 units to the left, and vector C carries you 42.324 units to the left in the x-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

For vector B:

The length of the adjacent side (x-component) is given by: cos(237°) = -0.7252 (since cosine is negative in the second and third quadrants)

The x-component of vector B is therefore: 120 x -0.7252 = -86.424

For vector C:

The length of the adjacent side (x-component) is given by: cos(188°) = -0.1997 (since cosine is negative in the second and third quadrants)

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.

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

Answers

J and V are different units of measurement and cannot be directly converted as they measure different quantities.

J is the unit of measurement for energy or work in the International System of Units (SI), while V is the unit of measurement for electrical potential difference or voltage.

To convert J (joules) to V (volts), you would need to know the amount of energy involved and the electrical charge involved in the process.

One formula that relates energy, charge, and voltage is:

V = E/Q

where V is voltage, E is energy, and Q is electric charge. If you know the values of E and Q, you can use this formula to calculate the voltage.

For example, if you have 1 joule of energy and 1 coulomb of electric charge, you can calculate the voltage using the formula:

V = 1 J / 1 C = 1 V

So, in this example, 1 joule of energy is equivalent to 1 volt of electrical potential difference when there is 1 coulomb of electric charge involved.

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.

Hope this helps!

a rubber ball bounces off of a wall with an initial speed v and reverses its direction so its speed is v right after the bounce. as a result of this bounce, which of the following quantities of the ball are conserved? (there could be more than one correct choice.) a) the momentum of the ball b) both the momentum and the kinetic energy of the ball c) the kinetic energy of the ball d) none of the above quantities are conserved.

Answers

Here, both the momentum and kinetic energy of he ball are conserved. There is no change in the magnitude of the speed thus, its kinetic energy is conserved.

What is kinetic energy ?

The kinetic energy of an object is the energy generated by virtue  of its motion. It is related to its mass and velocity by the expression written below:

Ke = 1/2 mv²

The momentum of an object is the product of its mass and velocity. For an elastic collision both momentum and kinetic energy is conserved. But in the case of an inelastic collision, there is some energy loss and the kinetic energy is not conserved but momentum is conserved.

Here, the ball bounces by colliding with the floor, where its direction is changing but not the magnitude of speed. Hence, both the momentum and kinetic energy are conserved.

what is the combined mass in grams of objects that have masses of 0.2000 kg, 80.0g, 524mg

Answers

The combined masses 0.2000kg * 1 g/0.001kg = 200 g, 524 mg * 1g/ 1000 mg = 0.524 g, 200g + 80.0 g + 0.524 g=280.524 g.

Mass is commonly referred to as the quantity of matter contained within an object. It is most usually assessed as inertial mass, which refers to an object's tension to acceleration given a given net force.

Matter, on the other hand, is defined somewhat loosely in science and cannot be strategically placed. In physics, mass is a statistical expression of inertia, which is a fundamental precept of all matter.

It is, in influence, the highly resistant that a cell of matter provides to a modification in its speed or placement when a force is applied to it. The smaller the start changing created by an applied force, the greater the mass of the body.
