Asmall, 2.00-mm-diameter circular loop with r = 1.00×10^−2 ω is at the center of a large 100-mm-diameter circular loop. both loops lie in the same plane. the current in the outer loop changes from +1.0a to −1.0a in 0.100 s . what is the induced current in the inner loop?

Part a constants huck finn walks at a speed of 0.60 m/s across his raft (that is, he walks perpendicular to the raft's motion what is huck's velocity (speed and direction) relative to the river bank? express your answer to three significant figures and include the appropriate units. relative to the shore)

Ahot-air balloonist, rising vertically with a constant speed of 5.00 m/s releases a sandbag at the instant the balloon is 40.0 m above the ground. after it is released, the sandbag encounters no appreciable air drag. compute the velocity of the sandbag at 0.250 s after its release.

Which of the following are guidelines to follow for obtaining accurate observations
