The light a planet receives from the sun (per square meter of planet surface) decreases with the square of the distance from the sun. so a planet that is twice as far from the sun as earth receives (1/2)2 = 0.25 times (25%) as much light and a planet that is three times as far from the sun receives (1/3)2 = 0.11 times (11%) as much light. how much light is received by the moons of jupiter and saturn (compared to earth), worlds which orbit 5.2 and 9.5 times farther from the sun than earth?

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
