What is the wave speed of a wave that has a frequency of 50 Hz and a wavelength of 0.10 m? What is the frequency of a wave that has a wave speed of 20 m/s and a wavelength of 0.50 m?

a) What is the wave speed of a wave that has a frequency of 50 Hz and a wavelength of 0.10 m?

5m/s

b) What is the frequency of a wave that has a wave speed of 20 m/s and a wavelength of 0.50 m?

40Hz

Explanation:

a) What is the wave speed of a wave that has a frequency of 50 Hz and a wavelength of 0.10 m?

Wave speed(v) = Frequency(f) × Wavelength (λ)

= 50Hz × 0.10m

=5m/s

b) What is the frequency of a wave that has a wave speed of 20 m/s and a wavelength of 0.50 m?

The formula for Frequency when given wave speed and wave length = Wave speed/ wave length

f = v/λ

Frequency = 20m/s ÷ 0.50m

Frequency = 40Hz

the answer is 3.1 his answer is wrong mines is right

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.
