Ostart the analysis of this circuit you must write energy conservation (loop) equations. each equation must involve a round-trip path that begins and ends at the same location. each segment of the path should go through a wire, a bulb, or a battery (not through the air). how many valid energy conservation (loop) equations is it possible to write for this circuit

Explain earth's motion, using the terms "precession" and "rotation" in your answer.

Two balls, each with a mass of 0.5 kg, collide on a pool table. is the law of conservation of momentum satisfied in the collision? explain why or why not

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
