Lawrence is able to lift 100kg to a height of 1.5m in 0.75 seconds. how much power did lawrence use?

Power= 1306.67 Watt

Explanation:

Power

The concept of power is related to how long it takes to some agent to do work.  The work done by a force is

Where is the displacement. The operation is known as dot-product which results in a scalar equal to the magnitude of the projection of F by the distance.

The power can be computed by

In this case, the force Lawrence is applying is the necessary to lift the object and beat its weight, so

The power is:

answer: its c lololo

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

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

= final temperature = ?

using the equation
