(a) 0.500c to 0.900c
Energy required is 0.582 MeV
(b) 0.900c to 0.990c
Energy required is 2.45 MeV

Answer:
Explanation:
From the question we are told that
Nucleus diameter
a 12C nucleus
Required kinetic energy
Generally initial speed of proton must be determined,applying the law of conservation of energy we have
where
=initial kinetic energy
=final kinetic energy
=initial electric potential
=final electric potential
mathematically
where
=distance b/w charges
=nucleus charge
=constant
=proton charge
Generally kinetic energy is know as
Therefore
Generally equation for radius is
Mathematically solving for radius of nucleus
Generally we can easily solving mathematically substitute into v_1
Therefore the proton must be fired out with a speed of
Answer: D) wavelength
Explanation:
The energy of an electromagnetc wave is given by the following formula:
(1)
Where:
is the Planck constant
is the frequency
Now, the frequency has an inverse relation with the wavelength :
(2)
Where is the speed of light in vacuum
Substituting (2) in (1) we have:
(3)
This means the amount of energy an electromagnetic wave carries depends on its wavelength (or its frequency), because the speed of light and are constant.
