1.	A block of mass 1 kg is kept on incline plane inside lift as shown in figure. If lift starts accelerating up at 2 m/s2 from rest then work done by frictional force in 1 second is (in J)( g = 10 m/s2) Friction between block and plane is 0.8.
Answer» A block of mass 1 kg is kept on incline plane inside lift as shown in figure. If lift starts accelerating up at 2 m/ $s^{2}$ from rest then work done by frictional force in 1 second is (in J) ( g = 10 m/ $s^{2}$ ) Friction between block and plane is 0.8.

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?
