Answer» In the figure shown below, coefficient of friction between the $3 kg$ block and ground varies with time as $μ = 0.02 t$ and the force acting on the block is given by $F = 5 t$ . Then, work done by the friction force on the $2 kg$ block up to $5 sec$ , from the frame of reference of the $3 kg$ block is: [Take $g = 10 {m/s}^{2}$ ]

Two speakers S1 and S2 are derived from the same amplifier and placed at the same distance from x-axis as shown in figure. The speakers vibrate in phase at 680 Hz. A man stands at a point on the x-axis at a very large distance from the origin and starts moving parallel to the y-axis. The speed of sound is 340 m/s. Then, at what angle θ with the x− axis will the intensity of sound drop to a minimum for the first time?
