Q1. At sea level, at latitude where, the pendulum that takes 2.00s for a complete swing back and forth has a length of 0.993m. What is the value of g in m/s2 at the location where the length of such a pendulum is 0.970m?

Q2. Beats and Standing Waves Two loudspeakers are placed at either end of a gymnasium, both pointing toward the center of the gym and equidistant from it. The speakers emit 266 {rm Hz} sounds that are in phase. An observer at the center of the gym experiences constructive interference.

Assume the observer walks toward one speaker with a speed of 1.35 {rm m/s}.
