What is the speed of a periodic wave with a frequency of 4.5 hz and a wavelength of 0.9m?

4.05 m/s

Explanation:

Frequency f and wavelength lambda are related to each other through the propagation speed v as shown below. That allows us to caclulate the speed when f and lambda are known:

The speed of the wave is 4.05 m/s.

scientific laws are the result of testing theories and proving them to be facts.

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.
