We must use two formulas of energy first how energy is related to wavelength:
Such that , c is the speed of light in a vacuum and h is Plank's constant.
And the second equation is how energy relates to voltage:
Such that q is the charge of the particle (in this case the electron) and V is voltage. By substituting the second equation into the first we have:
We know that:
And so:
Mantle I think idrk cuz of erosion
Answer:
D
Explanation:
heat is an energy that transfers from a hot body to cold body
2kg ball
A=f/m
Higher mass is less acceleration
