Answer: 4.43*10^-21kg

Explanation:

this topic deals with electromagnetic wave radiation energy, that was first introduced by Max Planck which is mathematically, E = hf

Given

Speed of object, v= 185m/s

Wavelength, λ=0.810fm

Planck’s constant, h=6.63*10^-34Js

Mass of object, m=?

Solution….

1fm = 1 * 10^-15m

Therefore, 0.810fm = .810 * 1 * 10^-15

= 8.1 * 10^-16m

De Broglie states that λ=h/mu

m=h/λu

substituting the values in the equation, we have

m = (6.63*10^-34)/(8.1*10^-16 * 185)

m = 6.63*10^-34/1.5*10^-13

m = 4.43*10^-21kg

Below is an attachment containing the solution.
