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

Skater begins to spend with arms held out at shoulder height. The skater wants to match the speed of the spin to the beat of the
Aleksandr [31]

Answer:

the moment of inertia with the arms extended is Io and when the arms are lowered the moment

I₀/I > 1    ⇒   w > w₀

Explanation:

The angular momentum is conserved if the external torques in the system are zero, this is achieved because the friction with the ice is very small,

           L₀ = L_f

           I₀ w₀ = I w

          w =\frac{I_o}{I} w₀

where we see that the angular velocity changes according to the relation of the angular moments, if we approximate the body as a cylinder with two point charges, weight of the arms

          I₀ = I_cylinder + 2 m r²

where r is the distance from the center of mass of the arms to the axis of rotation, the moment of inertia of the cylinder does not change, therefore changing the distance of the arms changes the moment of inertia.

If we say that the moment of inertia with the arms extended is Io and when the arms are lowered the moment will be

        I <I₀

        I₀/I > 1    ⇒   w > w₀

therefore the angular velocity (rotations) must increase

in this way the skater can adjust his spin speed to the musician.
