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

where is the circuit diagram ?

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
