30 degrees downward form the horizontal. Find the work done by the shopper on the
cart as he moves down a 15 m aisle to the tofu section.

If the mass of the cart (24kg), from problem 1, and we neglect friction, how fast will the cart
be moving when it reaches the tofu section if it started from rest?

The shopper brings the cart to rest is 2.7 s when he reaches the tofu. What power
does he exert in stopping the cart?

You take the bus with your bike to the top of Twin Peaks in San Francisco. You are

A 1500 kg car starts at rest and speeds up to 3 m/s with a constant acceleration. If the
car reaches its final speed in 1.2 s, what is its acceleration?

How far does the car travel in that time?
• What is the car's gain in kinetic energy?
• What power is exerted by the engine?

Answers

Answer 1

Answer:

Work done by the shopper on the cart: The force of 40 N at an angle of 30 degrees downward from the horizontal can be resolved into its horizontal and vertical components. The horizontal component of the force is:F_horizontal = F * cos(theta) = 40 N * cos(30) = 34.64 N


The work done by the shopper on the cart is equal to the force applied multiplied by the distance moved, multiplied by the cosine of the angle between the force and the displacement. In this case, the displacement is 15 m, and the angle between the force and the displacement is 30 degrees. Therefore:Work = F * d * cos(theta) = 34.64 N * 15 m * cos(30) = 448.5 J


Speed of the cart at the tofu section: The initial potential energy of the cart and shopper is equal to their combined mass (85 kg) multiplied by the acceleration due to gravity (9.81 m/s^2) multiplied by the height of Twin Peaks (600 m). 

Therefore: Potential energy = m * g * h = 85 kg * 9.81 m/s^2 * 600 m = 498,690 J


Since the shopper neglects friction, all of the potential energy is converted into kinetic energy at the bottom of the hill. The kinetic energy of the cart and shopper can be found using the formula:


Kinetic energy = 0.5 * m * v^2

where m is the mass of the cart and shopper, and v is their speed.

Therefore:Kinetic energy = 0.5 * 85 kg * v^2 Since the potential and kinetic energies are equal, we can set them equal to each other and solve for the speed v: Potential energy = Kinetic energym * g * h = 0.5 * m * v^2v = sqrt(2 * g * h) = sqrt(2 * 9.81 m/s^2 * 600 m) = 109.43 m/s


Power exerted by the shopper in stopping the cart:The shopper brings the cart to rest over a distance of 15 m in a time of 2.7 s. The average force exerted by the shopper on the cart can be found using Newton's second law: F = m * a = m * (v_f - v_i) / twhere m is the mass of the cart, v_i is the initial speed of the cart (which is zero), v_f is the final speed of the cart, and t is the time taken to stop the cart. Solving for F gives:F = m * (v_f / t)The work done by the shopper in stopping the cart is equal to the force applied multiplied by the distance moved, which is 15 m. Therefore:Work = F * d = m * (v_f / t) * d = 24 kg * (0 - 0) / 2.7 s * 15 m = 0 JSince no work is done in bringing the cart to rest, the power exerted by the shopper is zero.Acceleration due to gravity on the unknown planet:The final speed of the 4 kg ball is 12 m/s, and it falls a distance of 60 m. The initial speed is zero, so the final velocity is equal to the velocity acquired due to gravity. The final velocity can be found using the formula:v_f^2 = v_i^2 + 2 * g * hwhere v_i is the initial velocity (which is zero), h is the height fallen, and g is the acceleration due to gravity.

how distance will it take to safely pass another car, traveling at 45 mph?

Answers

It would require at least 732 feet of clear, straight road to pass the other car safely while traveling at 45 mph, assuming a 2-second following distance and 10 seconds to complete the passing maneuver.

The distance required to safely pass another car while traveling at 45 mph depends on several factors, including the speed of the other car, the speed of the passing car, and the time required to complete the passing maneuver.

The general rule of thumb for passing another car safely is to allow at least a 2-second following distance between your car and the car in front of you, and then add additional distance to account for the time required to complete the passing maneuver. This means that if the other car is traveling at 45 mph, you should be at least 2 seconds behind them before attempting to pass.

Assuming that your car is also traveling at 45 mph and you need 10 seconds to complete the passing maneuver, the total distance required to pass the other car safely would be:

Distance = (2 seconds following distance) x (45 miles/hour) + (distance traveled during passing maneuver)

The distance traveled during the passing maneuver depends on the speed of your car and the length of time required to complete the pass. If you are traveling at 60 mph during the passing maneuver, the distance traveled would be:

Distance traveled during passing maneuver = (60 miles/hour) x (10 seconds) = 600 feet

Substituting this value into the equation, we get:

Distance = (2 seconds) x (45 miles/hour) + 600 feet = 132 feet + 600 feet = 732 feet

A copper wire is stretched so that its length increases and its diameter decreases. As a result, a) both the wire resistance and resistivity increase. b) the wire resistance increases but its resistivity stays the same. c) the wire resistance increases and its resistivity decreases. d) the wire resistance decreases but its resistivity stays the same. e) both the wire resistance and resistivity decrease.

Answers

Answer:

C. The wire resistance increases and its resistivity decreases. When a copper wire is stretched so that its length increases and its diameter decreases, the increase in length makes the wire more resistant to electrical current. Since resistivity takes into account the wire's cross-sectional area, the decrease in diameter causes its resistivity to decrease as well.

Answer:

The correct answer is (b) the wire resistance increases but its resistivity stays the same.

Explanation:

The electrical resistance of a wire is given by the formula R = (ρL)/A,

(where R is resistance,

ρ is resistivity,

L is length,

A is the cross-sectional area of the wire)

When we stretched the copper wire so that its length increases and its diameter decreases, both the length and area of the cross-section of the wire changes. The length increases, which means the resistance will increase. The cross-sectional area decreases, which means the resistance will also increase.

Since the resistivity of copper is a constant that depends on the material, it will not change as a result of stretching the wire. Therefore, the correct answer is (b) the wire resistance increases but its resistivity stays the same.

two charges, -2q and q, are located on the x-axis, as shown above. point p, at a distance of 3d from the origin o, is one of two points on the positive x-axis at which the electric potential is zero. how far from the origin o is the other point?

Answers

The distance from the origin to the other point  is 7d.

To find the distance of the other point on the positive x-axis where the electric potential is zero, we can use the principle of conservation of energy. The electric potential energy at any point P on the x-axis is given by the equation:

                               V = k(2q/q)d - k(2q/q)(4d) + k(q/q)(x - 3d)

where,

k is Coulomb's constant and

x is the distance of point P from the origin O.

At the two points on the positive x-axis where the electric potential is zero, the electric potential energy is equal to zero. Therefore, we can set V equal to zero and solve for x to find the two points.

                            0 = k(2q/q)d - k(2q/q)(4d) + k(q/q)(x - 3d)

Simplifying and solving for x, we get:

x = 7d

relative humidity can range from ____________ and is used by meteorologists to calculate ____________ .

Answers

Relative humidity is a crucial weather parameter that can range from 0% to 100% and is used by meteorologists to calculate various weather conditions like dew point, heat index, and precipitation.

Relative humidity is a measure of the amount of water vapor present in the air, expressed as a percentage of the maximum amount of water vapor that the air could hold at a given temperature. The range of relative humidity can vary widely depending on location, season, and weather conditions. Generally, relative humidity can range from as low as 0% in very dry environments to as high as 100% in extremely humid conditions.

Meteorologists use relative humidity as a key parameter to calculate several weather conditions such as dew point, heat index, and precipitation. The dew point is the temperature at which the air becomes saturated with water vapor, resulting in the formation of dew or fog. Heat index is a measure of how hot it feels. Precipitation is influenced by relative humidity as it determines how much moisture is present in the air that can condense and fall as rain or snow.

To convert Pascal (Pa) to Kilopascal (kPa), you can use the following formula:1 kPa = 1000 Pa and 1 Pa = 0.001 kPa

Pascal's theory refers to the scientific contributions of Blaise Pascal, a French mathematician, physicist, and philosopher who lived in the 17th century. Pascal's work made significant contributions to several areas of science, including mathematics, physics, and hydrodynamics.

One of Pascal's most famous contributions to science is his work on hydrostatics, the study of fluids at rest. He discovered that the pressure exerted by a fluid at rest is the same in all directions, a principle known as Pascal's law. This law has important applications in many fields, including hydraulic systems, which rely on the transfer of pressure through fluids to power machines.

Pascal also made contributions to the study of probability theory, including the development of a mathematical theory of probability and the use of probability to solve problems in gambling. He also made important contributions to the development of the mechanical calculator, a precursor to modern computers.

Therefore, to convert Pa to kPa, you can divide the value in Pa by 1000. For example, if you have a pressure of 5000 Pa and want to convert it to kPa, you can divide 5000 by 1000 to get:

This is the mean elevation of the ocean's surface. The accumulation of water from melting land-based glaciers and glaciers, as well as the augmentation of seawater as it warms, are the primary causes of global mean sea level rise.

The Kanchenjunga peak has been India's tallest mountain, rising over 8.5 thousand meters above sea level. It has five peaks and borders Nepal and India. This one was preceded by Nanda Devi, who stood at approximately 7.8 thousand meters.

MSL is an abbreviation for mean sea level. It is used as one of many altitude determinants by both aircraft and drone pilots. It is, however, not a standard measure that defines the space above.

To accelerate to high speeds quickly, a racing car is built with a very powerful engine and a body with very little mass. Which newtons laws is used and explain please

Answers

The situation described in the question can be explained by Newton's Second Law of Motion, which states that the acceleration of an object is directly proportional to the force applied to the object, and inversely proportional to its mass. This law is expressed by the following equation:

F = ma

where F is the net force applied to an object, m is the mass of the object, and a is the resulting acceleration.

In the case of the racing car, a powerful engine produces a large net force that is applied to the car. Because the mass of the car is very small, the acceleration produced by this force is correspondingly very large. This allows the car to accelerate very quickly to high speeds.

This is also related to Newton's First Law of Motion, which states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity, unless acted upon by an external force. In the case of the racing car, the powerful engine provides the external force needed to overcome the car's inertia and get it moving. Once the car is in motion, it will continue to move at a constant velocity unless another force, such as friction or air resistance, acts to slow it down.
