Answer and see the solution →Give two changes that would increase the pressure exerted by a person standing on the ground.
Question 8
2 marks · Easy
Answer and see the solution →A student places a brick weighing 60 N flat on the ground.
(a)[1 mark]The area of contact is 0.15 m². Calculate the pressure exerted by the brick on the ground.
(b)[1 mark]If the student stands the brick on its end, the area of contact becomes 0.05 m², but the weight is unchanged. Explain what happens to the pressure and why.
