A sound wave has a frequency of 1665 Hz and a pressure amplitude of 1.13 x 10^-3 Pa. What were (a) the displacement amplitude and (b) the intensity of the wave emitted by the ear? the equation i used for a is sm=delta(pm)/(vpw) where p is the density, sm is the displacement amplitude, pm...

Two sinusoidal waves of the same frequency are sent in the same direction along a taut string. One wave has an amplitude of 5.0 mm, the other 8.0 mm. (a) what phase difference between the two waves results in the smallest amplitude of the resultant wave? (b) what is that smallest amplitude? (c)...

Two particles execute simple harmonic motion of the same amplitude and frequency along close parallel lines. They pass each other moving in opposite directions each time their displacement is half their amplitude. What is their phase difference?

A projectile is shot directley away from Earth's surface. Neglect the rotation of Earth. What multiple of Earth's radius RE gives the radial distance a projectile reaches if (a) its initial is .500 of the escape speed from Earth and (b) its initial kinetic energy is .500 of the kinetic energy...
