A sled with a mass of 25.0 kg rests on a horizontal sheet of essentially frictionless ice. It is attached by a 5.00-m rope to a post set in the ice. once given a push, the sled revolves uniformly in a circle around the post. If the sled makes five complete revolutions every minute, find the F exerted on it by the rope.

The value is  

Explanation:

From the question we are told that

    The mass of the shed is  

    The length of the rope is  

    The angular speed of the shed is

Generally the force exerted on the shed is mathematically represented as

=>  

=>      

your answer is c! hope this : )

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

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

= final temperature = ?

using the equation
