To solve any problem in math or physics, you collect all the formulas,
laws, rules, and equations that you know about the subject, then, along
with the given information, use them to find the missing information.
So the answer to "how" really depends on what information you're given.
Answer:
The wavelength is
Explanation:
Given that,
Speed
Mass of proton
We need to calculate the wavelength
Using formula of de Broglie wavelength
Put the value into the formula
Hence, The wavelength is
B, reduce the mass. hope this helps
Choice A ... I = V/R ... is a correct form of Ohm's Law.
