Answer:

The acceleration of the elevator is 1.8 m/s².

Explanation:

Given that,

Mass of elevator = 625 kg

Tension = 7250 N

We need to calculate the acceleration

Using equation of balance

T-mg=ma

Where, T = tension

m = mass

a = acceleration

Put the value into the formula

7250-625\times9.8=625\times a

a=\dfrac{7250-625\times9.8}{625}

a=1.8\ m/s^2

Hence, The acceleration of the elevator is 1.8 m/s².

Explanation:

7250=625(g+a)

11.6=10+a

1.6=a

Water evaporates from the surface of the land and oceans, rises and cools, condenses into rain or snow, and falls again to the surface as precipitation. The water falling on land collects in rivers and lakes, soil, and porous layers of rock, and much of it flows back into the oceans. The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth. so that will be probs the best i can do
