1.	Block A and B in the figure are connected by a bar of negligible weight. If A=B=170 kg and μA=0.2 and μB=0.4, where μA and μB are the coefficients of limiting friction between the blocks and the plane, calculate the contact force on the bar due to A (g=10 m/s2)
Answer» Block $A$ and $B$ in the figure are connected by a bar of negligible weight. If $A = B = 170 kg$ and $μ_{A} = 0.2$ and $μ_{B} = 0.4$ , where $μ_{A}$ and $μ_{B}$ are the coefficients of limiting friction between the blocks and the plane, calculate the contact force on the bar due to $A$ $(g = 10 {m/s}^{2})$

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?
