You are in a room in a basement with a smooth concrete floor (friction force equals 40 n) and a nice rug (friction force equals 55 n) that is 3 m by 4 m. however, you have to push a very heavy box from one corner of the rug to the opposite corner of the rug. will you do more work against friction going around the floor or across the rug, and how much extra?

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?
