The graph below shows the force on an object of mass M as a function of time. For the time interval 0 to 4 s, the total change in the momentum of the object is -
-Change in p = 0kgm/s
-Change in p = -20kgm/s
-Indeterminable unless the mass is known
-Change in p = 40kgm/s

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?
