What is the density of an object with a mass of 120g and a volume of 7ml

a book with the mass of 1 kg is sliding to the left on a table. if the frictional force on the book is 5 N, calculate the books acceleration. is it speeding up or slowing down

Two blocks are in contact on a frictionless, horizontal tabletop. An external force, F, is applied to block 1, and the two blocks are moving with a constant acceleration of 2.70 m/s2. Use M1 = 3.03 kg and M2 = 6.40 kg.

Mirages are due to: interference refraction reflection scattering

As you throw a ball, you exert a force on that ball of 4.2 N. You exert this force on the ball while the ball moves a distance of 0.50 m. The ball then leaves your hand and travels a horizontal distance of 8.5 m to your friend.
