When the tucurui dam was constructed in northern brazil, the lake that was created covered a large forest of valuable hardwood trees. it was found that even after 15 years underwater the trees were perfectly preserved and underwater logging was started. during the logging process a tree is selected, trimmed, and anchored with ropes to prevent it from shooting to the surface like a missile when cut. assume that a typical large tree can be approximated as a truncated cone with a base diameter of 8 ft , a top diameter of 2 ft , and a height of 100 ft . determine the resultant vertical force that the ropes must resist when the completely submerged tree is cut. the specific gravity of the wood is approximately 0.6.

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?
