What do you think car designers do if the damage caused by a crash test is too severe?

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

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?
