Explanation:
Pressure of a liquid :
Liquids also exert pressure as that in case of solids. We can understand it as the fact that it is impossible to hammer a nail with liquid. That's why liquid exert pressure on its surface. The formula for the pressure in liquid is given by :
Where
= density of liquid
g = acceleration due to gravity
h = height
The SI init of pressure is Pascal and it is dented by Pa.
Answer: Velocity can best be described as, the speed in a given direction.
Explanation: To find the answer, we need to know more about the Velocity of a body.
<h3>What is Velocity of a body?</h3>
- Velocity is the rate of change of displacement.
- It's a vector quantity and is measured in m/s.
- It can be positive, negative or zero.
- A body is said to be in uniform motion, then its velocity remains constant.
- Change in velocity can be a change in speed.
- The magnitude of velocity is less than or equal to speed.
Thus, we can conclude that, the option C is best describing velocity.

Just a guess without asking Google, that without the sun's gravity holding us in orbit, we would end up drifting whatever direction we were headed as it disappeared?
Archimedes' principle states that a body immersed in a fluid is subjected to an upwards force equal to the weight of the displaced fluid. This is a first condition of equilibrium. We consider that the above force, called force of buoyancy, is located in the centre of the submerged hull that we call centre of buoyancy.
