What effect would decreasing the distance between objects have on their gravitational attraction to each other?
Lady_Fox [76]
Decreasing the distance between two objects having a considerable mass would increase the attraction on gravitation. The reverse is true that if you separate or inrease the objects distance would substantially decrease their gravitational attraction. Most object in our planet is held by its gravitational force towards it's center.

how much power is needed to lift a box with a force of 780 newtons over a distance of 2 meters in 45 seconds
-BARSIC- [3]

Answer:

<h2>34.67 W</h2>

Explanation:

Power is the rate at which work is done and can be found by using the formula

p =  \frac{w}{t}  \\

p is the power in Watts (W)

w is the workdone in joules

t is time in s

but workdone = force × distance

From the question

force = 780 N

distance = 2 m

workdone = 780 × 2 = 1560 N

Since we now have the value of workdone we can find the power

We have

p =  \frac{1560}{45}  = 34.6666666... \\

We have the final answer as

<h3>34.67 W</h3>

Hope this helps you
