Billiard ball a of mass ma = 0.117 kg moving with speed va = 2.80 m/s strikes ball b, initially at rest, of mass mb = 0.141 kg . as a result of the collision, ball a is deflected off at an angle of θ′a = 30.0∘ with a speed v′a = 2.10 m/s, and ball b moves with a speed v′b at an angle of θ′b to original direction of motion of ball a.

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?
