Answer:
DeBroglie wavelength is
Frequency is
Explanation:
Mass of electron = 9.10938356 × 10⁻³¹ kg
Planck's constant = h = 6.626 × 10⁻³⁴ m²kg/s
Speed of light = c = 3×10⁸ m/s
DeBroglie wavelength is
Frequency is
A fan may be used to model an atom because the fan blades form something similar to a electron cloud. But there is really nothing to model the neutrons and protons. Also the fan is flat like where an atom is more 3-D sphere-like.
hope this helps
Ur welcome

Answer:
39 miles
Explanation:
we will make your house to be the central point in the four cardinal points.
Please follow the diagram on the attachment to get the movement clearly.
First, you move to a dry cleaners 12miles east of your house, and then to a grocery store 15miles west of your house.
This means you must have moved back to your house before going to the grocery which is 15miles west of your house.
so to and fro from your house to dry cleaners = 12*2 = 24 miles.
Then the total distance you cover will be = 24 +15 = 39 miles
