what's the difference between work and power

Answers

Answer 1

Work is defined as the process of energy transfer to the motion of an object through the application of force. ... Power is defined as the amount of energy transferred in unit time. The SI unit of power is the watt.

You need to have power or energy, to be able to work. When you reach another lesson, you will learn about time, which is the flow of work you have done. You need more work than time for your work to count.

If you need more help, don't hesitate to ask!

May I please have brainliest?

Answer 2

WORK is the amount of energy used to get something done.

POWER is the RATE at which the energy is used and the work is done.

Do all the stars move in the sky ? Explain​

Answers

The earth rotates on its axis from west to east. Therefore, all the stars in the sky (except the pole star) seem to move from east to west. Pole star is located along the axis of rotation of the Earth in the north direction. Thus, it seems to remain stationary at a point in the sky and all other stars appear to move around the pole star.

Which is heavier , a kilogram of lead or a kilogram of a polystyrene beads ?​

Answers

Answer:

They weight the same, they're both 1 kilogram

The weight of the given objects is the same since they have equal mass.

Weight of object

The weight of an object is the gravitational pull of earth on the object. Weight is vector quantity because it varies from place to place due to difference in acceleration due to gravity.

The weight of 1 kg lead

W = mg

W = 1 x 9.8

W = 9.8 N

The weight of 1 kg polystyrene

W = mg

W = 1 x 9.8

W = 9.8 N

Thus, the weight of the given objects is the same since they have equal mass.

Answers

Complete question:

A 0.144 kg baseball approaches a batter with a speed of 20m/s . The batter lines the ball directly back to the pitcher with a speed of 30m/s . Find the impulse exerted on the ball . If the bat and ball were in contact for 0.012 sec , find the average force exerted on the ball by the bat

Answer:

(1) The impulse exerted by the ball is 7.2 kg.m/s

(2) The average force exerted on the ball by the bat is 600 N.

Explanation:

Given;

mass of the baseball, m = 0.144 kg

velocity of the baseball, v₁ = 20 m/s

velocity of the batter, v₂ = -30 m/s (opposite direction to the ball's speed)

The impulse exerted by the ball is calculated as follows;

J = ΔP = mv₁ - mv₂

ΔP = m(v₁ - v₂)

ΔP = 0.144 [20 - (-30)]

ΔP = 0.144 ( 20 + 30 )

ΔP = 0.144 (50)

ΔP = 7.2 kg.m/s

The average force exerted on the ball by the bat is calculated as;

[tex]F = \frac{\Delta P }{t} \\\\where; t \ is \ time \ of \ contact= 0.012 \ s\\\\F = \frac{7.2}{0.012} \\\\F = 600 \ N[/tex]

Denver, Colorado is located near the rocky mountains. Which list of controls below would have the strongest influence on the weather in Denver.

A ) Ocean currents, distance from large bodies of water, and altitudes
B ) Altitude, topography, and ocean currents.
C ) Latitude, altitude, and topography
D ) Topography, ocean currents, and latitude.

Answers

Answer:To understand the regional and local climates of Colorado, you must begin with a basic knowledge of Colorado's topography. Colorado lies astride the highest mountains of the Continental Divide. Nearly rectangular, its north and south boundaries are the 41° and 37° N. parallels, and the east and went boundaries are the 102° and 109° W. meridians. It is eighth in size among the 50 states, with an area of over 104,000 square miles. Although known for its mountains, nearly 40 percent of its area is taken up by the eastern high plains.

Of particular importance to the climate are Colorado's interior continental location in the middle latitudes, the high elevation of the entire region, and the mountains and ranges extending north and south approximately through the middle of the State. With an average altitude of about 6,800 feet above sea level, Colorado is the highest contiguous State in the Union. Roughly three-quarters of the Nation's land above 10,000 feet altitude lies within its borders. The State has 59 mountains 14,000 feet or higher, and about 830 mountains between 11,000 and 14,000 feet in elevation.

D. Friction and air resistance

Answers

Answer: B An action-reaction force pair

Explanation: Took the exam

The arrows in this photograph represent: An action-reaction force pair. Hence, option (B) is correct.

What is  action-reaction force pair?

When two bodies interact, they exert an equal and opposite force on one another in accordance with Newton's third law of motion. Action-reaction forces are made up of these forces.

"When one body exerts a force on the other body, the first body experiences a force that is equal in magnitude in the opposite direction of the force which is exerted," according to Newton's third law of motion.

According to the above assertion, there are always two forces operating on the objects involved in an interaction. The forces are of identical magnitude, but the direction of the force acting on the first object is different from the direction acting on the second.

Answers

Answer: A. An ice hockey player picks up a trophy as he slides past it

Explanation:

A PE X

The statement that best describes a perfectly inelastic collision is

C. A surfer falls off of his surfboard when a wave hits him.

What is collision?

A collision is the interaction between two bodies in such a way that the momentum and velocity of one body gets changed due to the presence of other body. There are three types of collision-

1. Elastic collision

2. Inelastic collision

3. Perfectly inelastic collision.

In all types of collision , the momentum of the system before collision and after collision always remains same or we can say that momentum is conserved in collisions

What is elastic collision

An elastic collision is the one in which kinetic energy is also conserved and coefficient of restitution is one. Both the bodies move separately with different velocities after elastic collision.

What is inelastic collision ?

In inelastic collision  there is a loss of kinetic energy and coefficient of restitution is less than one.

What is perfectly inelastic collision?

In perfectly inelastic collision there is maximum loss of kinetic energy and coefficient of restitution is zero. Both the bodies stick together after collision and move with same velocity

What is coefficient of restitution ?

Coefficient of restitution is the  ratio of  relative velocity of separation after collision to relative velocity of approach before collision.

A surfer falls of his surfboard when a wave hits him is an example of perfectly inelastic collision because in this when water hits the surfers he falls of and sticks to the water , and will also now move with the velocity of water .

So  when the surfer falls off his surfboard when a wave hits him is perfectly inelastic collision.
