Humid tropical climates are climates that have no winters.
In order to calculate the angle, we can use the formula below for a constructive interference (the interference is constructive because the fringe is bright):
Where d is the distance between the slits, m is the order of the interference and lambda is the wavelength.
So, using d = 8.25 * 10^-5, m = 2 and lambda = 4.5 * 10^-7, we have:
Therefore the correct option is the second one.
Explanation:
Below is an attachment containing the solution.
the electrons should be in the outer valence levels/shells.
Well, an equilibrium means that no force are changing an object's inertia (current state of motion).
