    Answer:

    D) 1.5032 x 10^-10 J

    Explanation:

    The rest energy of a proton, E₀, follows the equation:

    E₀ = mp*rate²

    Where mass of proton, mp = 1.6726 x 10^-27kg

    rate = 2.9979 x 10^8 m/s (2.9979 x 10^9 m/s is not the speed light)

    E₀ = 1.6726 x 10^-27kg * (2.9979 x 10^8 m/s)²

    E₀ =1.5032 x 10^-10 J

    Right answer is:

    D) 1.5032 x 10^-10 J
