Answer:
0.2s
force = change in momentum/ time
time = change in momentum/time
Explanation:
first, let's find the change in momentum
pf-pi
5×(-2) - 5× 2
-20kgm/s = 20kgm/s(by changing the direction of whole system)
time = change in momentum/time
20/100
<u> 0.2s</u>
F = ma
F = (1000 kg)•(5 m/s^2)
F = 5000 N
The sun's energy flow through the earth's system by it moving through the earth's atmosphere.
<h2>
Answer</h2>
The volume will be <u>increased</u>
<h2>
Explanation</h2>
Look at the formula

If the mass increase the density will be increased because of their direct relationship. But in the case of constant mass. The volume increase the density will decrease because there is an inverse relationship exists between them. In the inverse relationship, the two objects perform differently. for example, if you are going to inflate the balloon, its volume will increase but density decrease
