An object moves in a circular orbit starting from rest. the orbit has a radius of 10 m. it takes 10 revolutions to reach its final speed of 10 m/s. a) how far did it travel from rest to its final speed (in meters)?
b) if it accelerated at a constant rate, what was its tangential accelerate during that time?
c) once it reaches its final speed, what is its centripetal acceleration?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
