The speed of a wave on a string is $150\, ms^{-1}$ when the tension is $120\, N$. The percentage increase in the tension in order to raise the wave speed by $20\%$ is

A 0.5 kg ball moving with a speed of 12 $ms^{-1}$ strikes a hard wall at an angle of 30$^{\circ}$ with the wall. It is reflected with the same speed and at the same angle. If the ball is in contact with the wall for 0.25 s, the average force acting on the wall is :-
