A force of 2.5n is applied for 5.0s to a mass of 5.0kg. What is the change in momentum?

The number of revolutions of two pulleys is inversely proportional to their diameters. If a 24-inch diameter pulley making 400 revolutions per minute is belted to an 8-inch diameter pulley, find the number of revolutions per minute of the smaller

The primary colors for paints are different for those used in a television because A. Paints reflect light instead of emit light B. Paints take out light from what light is shined onto them C. Both of A and C

An electron is traveling through a uniform electric field. The field is constant and given by E⃗ = (2.00*10-11N/C) i^ - (1.20*10-11N/C) j^. At t=0, the electron is at the origin and traveling in the x direction with a speed of 2.10 m/s.

Block B has mass 6.00 kg and sits at rest on a horizontal, frictionless surface. Block A has mass 2.50 kg and sits at rest on top of block B. The coefficient of static friction between the two blocks is 0.400.

Why do electromagnetic waves not require a medium for travel?

A lorry with a mass of 5000kg accelerates to overtake a caravan on the motorway. Its acceleration is 1.5m/s². What force must the engine be providing? You can ignore the effects of friction and air resistance

Norma kicks a soccer ball with an initial velocity of 10.0 meters per second at an angle of 30.0% if the ball moves though the air for 3.2 seconds what's the horizontal distance traveled by the ball

Suppose s (t) is the position of an object moving along a line at time t is greater than or equal to 0. What is the average velocity between the times t=a and t=b? What is the instantaneous velocity at t=a?

Estimate how long it would take one person to mow a football field using an ordinary home lawn mower. suppose that the mower moves with a 1-km/h speed, has a 0.5-m width, and a field is 360 ft long and 160 ft wide. 1 m = 3.281 ft.

Badri makes the table below to review the factors that affect the electric force between objects. Which change will correct the error in Badri's table?
