The gravitational force between two objects is most affected by their

suppose you supply energy to a machine at a rate of 700 w and that the machine converts 560 j into heat every second. At what rate does the machine do work

You drop a 14-g ball from a height of 1.5 m and it only bounces back to a height of 0.85 m. what was the total impulse on the ball when it hit the floor? (ignore air resistance.)

Why are conductors and insulators both required to construct the electrical wiring in our home

A magnetic field line must a. go on forever. b. form a closed loop. c. have a north and south pole. d. be created by a permanent magnet.

A speeder passes a parked police car at a constant velocity of 30.0 m/s. The police car starts from rest with a uniform acceleration of 2.44 m/s^2.

Josh rolled a bowling ball down a lane in 2.5 seconds. The ball travelled at a constant acceleration of 1.8 m/s/s down the lane and was traveling at a speed of 7.6 m/s by the time it reached the pins at the end of the lane.

How many meters of the rock wall eroded between 1910 and 1927?

As air temperatures increase, evaporation increases. Warmer temperatures also increase the capacity to absorb water vapor. More water vapor in the atmosphere accelerates the greenhouse effect.

What is the speed of a 50 g rock if its de Broglie wavelength is 3.32 x 10?

The difference between newtons first law of motion and newtons third law of motion
