Suppose gravity of earth suddenly becomes zero, then in which direction will the moon begin to move if no other celeastial body affects it?

In the figure. The straight wire AB is fixed, while the loop is free to move under the influence of the electric currents flowing in them. In which direction doe the loop begin to move? Give reason for your answer.

A trolley of mass 200 kg moves with a uniform speed of 36 km//h on a frictionless track. A child of mass 20 kg runs on the trolley from one end to the other (10 m away) with a speed of 4 m s^-1 relative to the trolley in a direction opposite to the its motion, and jumps out of the trolley. What is the final speed of the trolley ? How much has the trolley moved from the time the child begins to run ?

An archer stretches her bow while taking aim at the target. She then releases the arrow, which begins to move towards the target .Based on this informaion, fill up the gaps in the following statements using the following terms. Muscular,contact,non -contact,gravity, friction,shape, attraction While the arrow moves towards its target, the forces acting on it are due to................ of air.
