The tension on the string = <u>12 N </u>and acceleration of the mass = <u>2.4 m/s² </u>of the two masses .

<h3>Tension of a string :</h3>

The tension of  a given strand of string or rope is a result of the forces pulling on the rope from other  end. As a reminder, force = mass × acceleration. Considering , the rope is stretched tightly, any change in acceleration or mass in objects the rope is supporting will cause a change in tension within the rope.

<h3>Evaluating the numerical :</h3>

m₁ = 3kg

m₂ =  5kg

F = 20 N Applied on 3 kg

F - T = m₁a

T = m₂a                        ( T = tension )

F - m₂a = m₁a                ( a = acceleration )

F = ( m₁ + m₂ )a

20 N = ( 3 kg + 5 kg )a

a = 2.4 m/s²

When F is applied on 3 kg block

      T = m₂a

       T = 5 × 2.4

T = 12 N

<h3>What is acceleration explain?</h3>

Acceleration, is defined as  rate at which velocity changes with time, in terms of both speed and direction. some extent or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated whether or not the speed is constant, because the direction is continually changing

C) W = - 190 J

Explanation:

Notation

Wf = work done by the friction force (unknown)

Ff = force of the friction

Whitepunk [10]

Air for a diver comes out of a high pressure tank at - Same- pressure compared to the water around the diver (metered by the regulator).

This means the lungs are inflated with - Highly pressurized- gas.

This does not adversely affect the diver when deep underwater, because the entire environment around the diver is at -Same - pressure.

If the diver suddenly surface, the air in the alveoli in the lungs will still be at - a higher - pressure compared to the air around the diver, which will be at - a lower - pressure.

The gas in the diver's lungs will - expand - and can damage the alveoli.
