Q.4 State and define SI unit of pressure.

Q.5 How is pressure related to the thrust exerted on a surface?​

Answer 1

Answer:

thrust is force which is applied to an object when one pushes a body in same direction there is thrust large in opposite direction

b) an object will float if the buoyancy force exerted on it by the fluid balances it's weight

c) because it is more dense

d) pressure so unit is pascal it is defined as one Newton per square metre

e) force exerted by an object is perpendicular to the surface is thrust and pressure is force per unit area ..... . I hope it helps you☺
