Question

Prove that p=dgh.
Difference between sinking and floating
​Pls someone help!

Answer 1

Step-by-step explanation:

Hey there!!

Here,

we have,

As per the definition of pressure,

`p = (f)/(a)`

Putting f = m.g and keeping a constant.

`p = (m.g)/(a)`

Keeping m = d×v.

`p = (d * v * g)/(a)`

Keep v= a.h

`p = (d(a.h)g)/(a)`

Cancelling a from numerator and denominator,

we get,

p = hdg

Proved.

Difference between sinking and floating are:

• A body sinks when a liquid density is lessor than that of an object. Whereas, A body floats when the density of water is equal to the density of an object.
• In sinking the condition is d1(of water) > d2(of an object). Whereas, in floating the condition is d1(of water) = d2(of an object).

Hope it helps....
