    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
