Question

A brick of mass of 3kg has a base area of 600square cm when on one end and of 800square cm when lying flat.Calculate the pressure in each case.

Answer 1

Answer:

Q1)what force will exert a pressure of 50000 pascals on an area of 0.5 meter square ?

Q2)find out the area of a body which experiences a pressure of 500 pascals by a force of 100 N

Q3)calculate the pressure exerted by a force of 300N(newton) acting on an area of 30cm square

Q4)what will be force required to exert a pressure of 20000 pascal on an area of 1 cm square ?

so these are the questions to be answered ... referring to the answers you can give the solutions :) plzzzz help me out with this its urgent . it is to be submitted by tomorrow itself!!!

Answers for the above questions are :(Q1) 25000N (Q2) 0.2 meter square (Q3) 10 N cm-square = 100,000 pascal (Q4) 2 N

Answer 2

Explanation:

Pressure = force/area,. g=10 m/s^2

force=m×g = 3×10= 30N

Case 1. area = 600/10000 metre sq.

pressure = 30/0.06 = 500 N/m^2

Case 2. area = 800/10000 metre sq.

pressure = 30/0.08 = 375 N/m^2
