An 800-kg elevator is lifted vertically by a strong rope. Find the acceleration of the elevator if the rope tension is (a) 9000 N, (b) 7840 N, and (c) 2000N.

Explanation:

Given that,

Mass of an elevator, m = 800 kg

It is lifted vertically by a strong rope

The equation of motion, when the elevator is lifted vertically up is :

T-mg = ma

a is the acceleration of the elevator

We need to find the acceleration of the elevator if the rope tension is :

(a) 9000 N

Put T = 9000 N,

T-mg = ma

(b) 7840 N

Put T = 7840 N,

T-mg = ma

(c) 2000 N

Put T = 2000 N,

T-mg = ma

Hence, this is the required solution.

your answer is, orbit around the nucleus

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
