The distance covered by an object accelerating uniformly in fifth and seventh second are respectively 38m and 48m find the initial velocity ,the acceleration and the distance covered in five second

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?
