Two solenoids stand side-by-side. solenoid b differs from solenoid a in three respects. its total current is 2 times as great, it has 4 times as many coils, and it is 3 times as long. how do the magnetic fields inside the two solenoids compare? a.. a standing wave is generated.. b.. beats are produced.. c.. a traveling wave is generated.. d.. resonance occurs.. e.. the frequency of the resultant wave decreases.

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.

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)
