A boy of mass 50 kg exerts a pressure of 25000 pa calculate the area
which the force acts A = 0.02m²

A = 0.02 m²

Explanation: Solution:

Pressure is expressed in the formula:

P = F / A       where F = mg

  = mg /A

  = 50 kg ( 9.8 m/s²) / 25000 Pa

  =  0.02 m²

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

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

= final temperature = ?

using the equation

no

explanation:

no i dont know how to solve this you should probably try to google the answer
