The strength of the gravitational force between two objects depends on two factors: mass and distance. Suppose that two objects attract each other with a gravitational force of 16 units. If the distance between the two objects is
doubled, then what is the new force of attraction between the two objects?
A)
4 units
B
8 units C- 16 units

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
