Q1. A vertical scale on a spring balance reads from 0 to 205 N. The scale has a length of 10.0 cm from the 0 to 205 N reading. A fish hanging from the bottom of spring oscillates vertically at a frequency of 2.55 Hz. ignoring the mass of the spring, what is the mass of fish?
Q2. What is the largest wavelength that will give constructive interference at an observation point 171 from one source and 295 from the other source?
