Question

1) Fruite can easily be cut with a sharp knife.
2) The wall of a dam is broad at its base​

Answer 1

Answer:

1)

Why does it happe

While using a sharp knife, force exerted on the knife is acting on a very a narrow area of fruit. Pressure is inversely proportional to area where force is applied. So, a sharp knife can exert large pressure compared to a blunt knife for same force. Thus, fruits can easily be cut with a sharp knife.

2)This implies as the depth below the surface increases, the pressure of the fluid also increases. ... To withstand this pressure of the fluid, the wall of the dam is made broad at its base. Hence, the wall of a dam is broad at its base to withstand the pressure of the liquid.

Answer 2

Answer:

Yes ,became the pressure is low
