The hypotenuse of a right triangle ABC is 12.0 centimeters. The angle 0 is 41.0 degrees. what is the length of the side opposite to angle 0

How much work is done lifting a 9.10 kg box straight up onto a shelf that is 1.80 m high?

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

Aleaky 10-kg bucket is lifted from the ground to a height of 15 m at a constant speed with a rope that weighs 0.7 kg/m. initially the bucket contains 45 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 15-m level. find the work done. (use 9.8 m/s2 for g.) show how to approximate the required work by a riemann sum. (let x be the height in meters above the ground. enter xi* as xi.) lim n → ∞ n (9.8)(45−3 xi) i = 1 δx express the work as an integral. 0 dx evaluate the integral. (round your answer to the nearest integer.) j
