An electromagnetic wave has a frequency of 2.90 10hz. what is the wavelength of the wave?

103.3410748MHz

Explanation:

F=(C/λ)

Therefore:

λ = (C/F)

where C = 299,792,458 m/s

=> λ = 299,792,458/2.9010

= 103.3410748MHz

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.
