Microwaves travel at the speed of light, 3.00×
108 m/s.
When the frequency of microwaves is 7.76×
109 Hz, what is their wavelength?
Answer in units of m.

need to see circuit to get time constant

where are the vectors ?

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
