Question

prove that; 1 .p=d g h 2 .V=u+at please answer

Answer 1

Answer:

(1)Let's finding the force at the bottom of the container.

Let,

mass of the container = m

Volume of the container = V

density of the container = d

Area of the bottom = A

Height of the container = h

F = mg

Now,

Pressure = Force / Area

P = F/A

P = m g / A

dividing h on denometer and numerator,

P = mgh / Ah

P = mgh / V ( V = Ah )

P = d g h ( d = m/V)

(2) I will provide you with two types of proofs. Among these two I like logical the most…

Let us begin with Mathematical proof which is that we know that acceleration of a body is change in velocity (v-u) per unit time. Mathematically it is:

a=(v−u)/t

Multiplying t on both sides we get:

at=(v−u)

Adding u on both sides we get:

at+u=(v−u)+u

at+u=v
