Q1. Two speakers, 6.00 m apart, are driven by the same audio oscillator so that each one produces a sound consisting of two distinct frequencies, 1000 Hz and 1360 Hz. The speed of sound in the room is 350 m/s.
Q2. A 3.5 kg fish swimming 4 m/s swallows an absent minded 2 kg fish swimming toward it at a velocity that brings both fish to a halt immediately after lunch. What is the velocity v of smaller fish before lunch?
