g A planar loop of wire (i. e. the object would lie flat on a page) with areaAis oriented so it is parallel tothex−yplane. It is released from rest at a heightz=h >0 and accelerated downwards with constantaccelerationa. The loop has resistanceRand is exposed to a magnetic field~B= (h−z)2ˆz. a) Find how much current runs though the wire, include the direction when seen looking down from abovethe loop. b) How much energy was consumed by the loop since being released when it reaches the ground atz= 0

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.
