The acceleration due to gravity:
The motion of the centre of mass depends on:
In the arrangement, spring constant \(k=2\) N/m, masses \(M=3\) kg and \(m=1\) kg, friction coefficient 0.1. Amplitude is 10 cm. The time period of SHM will be
A cubical ball is taken to a depth of 200 m in sea. The decrease in volume observed is 0.1%. The bulk modulus of the ball is
In the relation \(y = r\sin(\omega t - kx)\), the dimensional formula of \(\dfrac{\omega}{k}\) is:
A wave motion has the function \( y = a_0 \sin(\omega t - kx) \). The graph in the figure shows how the displacement \(y\) at a fixed point varies with time \(t\). Which one of the labelled points shows a displacement equal to that at the position \(x = \dfrac{\pi}{2k}\) at time \(t = 0\)?
The frequency of a tuning fork P is $a%$ less than a standard fork A. The frequency of another fork Q is $b%$ greater than that of A. When P and Q are sounded together, $x$ beats are produced in one second. The frequency of the standard fork is (in Hz)
A metallic wire of density $d$ floats horizontally in water. The maximum radius of the wire so that the wire may not sink will be (surface tension of water = $T$)
