Question

Write the formulas to find :

a) Power

b) Work

c)Buoyant Force

Answer 1

hey friend.

we know that power is the rate of work done,

so. power(P) = work done/ time taken

P = W/t

or power is also equal to

Power(P) = Force × velocity

=) work is the product of force and displacement.

W = Force × displacement

Buoyant force is the force which we feel when we immersed in liquid.


Buoyant force = volume of part immersed × density of liquid × acceleration due to gravity.

Buoyant force = V dg

Answer 2

Formulas to find:-

a) Power:-

P = W ⁄ t

where,

P = power

W = work

t = time

b) Work:-

W = FS

where,

W = work

F = force

S = displacement

c) Bouyant Force:-

Fb = ρgV

where,

Fb or FB = bouyant force

ρ = density of the liquid

g = gravitational acceleration

V = volume of liquid displaced

Bouyant Force is equal to the weight (W) of the displaced fluid.
