If an electromagnetic wave has a frequency of 6 x 105 Hz, what is its wavelength? Use i=The speed of light is 3 x 108 m/s.
A. 2 x 103 m
B. 2 x 1012 m
C. 5 x 102 m
D. 5 x 1014 m

c)as speed changes, wavelength and frequency change.

everything changes!

iron would move it is magnetic there is a mag field around the current in the wire

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.
