1. The hearing range of a normal human ear is from 20 to 20000 Hz. If the speed of the sound in air is 340 m/s, what are the shortest and the longest wavelengths that the human ear can hear? 2. If the speed of wave in passing from medium A to medium B doubles while keeping the frequency constant, what happens to the wavelength? 3. Suppose that two-point charges, each with a charge of +1.00 Coulomb are separated by a distance of 1.00 meter. Determine the magnitude of the electrical force of repulsion between them.
