Using the rule-of-1 approach, what is the proportional change in centripetal acceleration, ac, for an object in a circular path when the tangential velocity is doubled? 2ac (doubles) 2 A sub c, (doubles) ac2 (halves) the fraction with numerator A sub c and denominator 2, (halves) ac4 (quarters) the fraction with numerator A sub c and denominator 4, (quarters) 4ac (quadruples)

Sarah and michelle work at a tech company that designs exercise apps. sarah tells michelle she has heard that james, their supervisor, interviewed with a competitor and may be leaving the company, which would open up a management position. what kind of power is sarah exerting?

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
