Answers
Answer:
1.)The pressure will be less. the pressure will be less on a large area and high on a low area.
2.) zero
3.) opposite to the motion of the body
4.)The pressure exerted by a liquid is small just under the surface of the liquid. But as we go we deeper in a liquid the pressure of liquid increases.As the depth of liquid increases the weight of liquid column pushing down from above increases and hence the pressure also increases
5.)The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
6.)the use of skis helps a person to slide smoothly over snow because the skisthe area over which the weight of the person acts.
7.)Force used by the worker is muscular force. Force can be push or pull such as opening, hitting, pushing etc. The worker carrying a brick this force is coming from the action of the muscles in our body.
8.) Pascal [Pa]
