Force calculation

Force = mass x acceleration

A.) 160

B.) 160 N

C.) 10 N

D.) 10

When an object is totally immersed in water, it's weight is recorded as 3.1N if it's weight in air is 4.9N calculate the upthrust acting on this object

Harry has two types of materials of the same mass, one is a piece of paper, the other a copper ball. (a) explain why the copper ball hits the ground first when both are dropped near the surface of the earth even if they experience the same

Calculate the magnitude of the force the jumper must exert on the ground to produce an upward acceleration 4.00 times the acceleration due to gravity.

Which statement best describes the kinetic theory of matter? Matter is made up of compounds that are in constant motion and have energy. Matter is made up of particles that seldom move and do not possess energy.

Why can we see our breath on a cold winter day
