susie and Mark perform an experiment to determine how gravity affects falling object Susie uses a small ball in the spam at Walmart kisses a piece of Styrofoam that has the same mass as a ball Susie and Mark drop their objects at the same time from the same height but the ball reaches the ground press in theory since the objects have the same mass they should reach the ground at the same time so which of the following factors is affecting the force of gravity on the objects

Steam enters an adiabatic diffuser at 150 kpa and 1208c with a velocity of 550 m/s. determine the minimum velocity that the steam can have at the outlet when the outlet pressure is 300 kpa.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
