Awave has a frequency of 15,500 hz and a wavelength of 0.20 m. what is the
speed of the wave? use the equation v=f>

3100 m/s

Explanation:

The relationship between frequency and wavelength of a wave is given by the wave equation:

where

v is the speed of the wave

f is its frequency

is the wavelength

For the wave in this problem,

f = 15,500 Hz

Therefore, the wave speed is

lol

explanation:

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
