Answer:

Given Data:

V2 ?

V1 = 200 ml,

P1 = 500kpa and P2 = 2500kpa

From Boyels law (Ideal gas law) Where temperature remains constant, Pressure is inversely proportional to volume.

P1 .V1 = P2 . V2 ; T=Constant

V2 = (P1.V1) ÷ P2

= (500×200) ÷(250)

= 400 ml

The final volume of the gas is 400 ml.

Note: Increased pressure decreases the volume or decreased pressure increase the volume as they are inversely proportional. Here in our answer pressure decreases from 500 kpa to 250 kpa so volume increases from 200 ml to 400 ml.

Two people push on the same door from opposite sides as shown. A man pushes on a door from the left. A woman pushes on the door

AURORKA [14]

Answer:

The door will move when the forces exerted by each individual becomes unbalanced.

Explanation:

The Door will only move when the forces exerted by each of the individual is unbalanced i.e. when the Torque is unbalanced

This is because there will only be a reaction or movement of an object when the applied force > resistant force acting on the object.

example : An object at rest will only move when the applied force is greater than the frictional forces acting on the object at rest.

Two masses of size m and 4m are connected by a massless thread and are strung over a frictionless pulley of radius R and moment-

tekilochka [14]

Answer:

Total kinetic energy of entire system is 3 mgl

Explanation:

Given two masses: m and 4m.

Since the pulley is frictionless and the thread is massless, the energy here is linked to the two masses.

Total kinetic energy of entire system = decrease in gravitational potential energy of the system.

Therefore, we have :

ΔKE = Δp

ΔKE = 4mgl - mgl

= 3 mgl

Total kinetic energy of entire system is 3 mgl
