A spring is used to measure the centripetal force. Since a spring will exert a restoring force equal to the force applied to it, the centripetal force can be verified by measuring the amount of force need to stretch the spring a distance. We will assume a spring constant of 9m/N, That is it 1 N of force to move the spring 9 meters. For 6 different radius, covering the radius scale, calculate the force needed to stretch the spring.

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?
