A 60g tennis ball moving with a speed of 7 m/s hits a wall at an angle of 55 ∘ with the wall. It bounces off the wall with the same speed at the same angle (but not directly backwards).

If the ball was in contact with the wall for 0.002s, what was the magnitude of the average force exerted by the wall on the ball?

Herbivores, carnivores, and omnivores are all types a. decomposers b. producers c. consumers d. biomes

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.

Which type of energy is transferred by convection currents?
