(a) 
The change in potential energy of the electron is given by:
where
is the magnitude of the electron's charge
is the magnitude of the electric field
d = 520 m is the distance through which the electron has moved
Substituting into the equation, we find
(b) 78 kV
The potential difference the electron has moved through is given by
where
is the magnitude of the electric field
d = 520 m is the distance through which the electron has moved
Substituting into the equation, we find
The answer is kinetic energy
Answer:
1.52 * 10⁵ K
Explanation:
When the temperature of a blackbody radiator increases, the overall radiated energy increases and the peak of the radiation curve moves to shorter wavelengths. When the maximum is evaluated from the Planck radiation formula, the product of the peak wavelength and the temperature is found to be a constant.
By Wien's Law,
λ * T = 2.898 * 10⁻³ mK
∴ T = 2.898 * 10⁻³/λ
Given λ = 19 nm = 19 * 10⁻⁹
T = 2.898 * 10⁻³ / 19 * 10⁻⁹
=1.52 * 10⁵ K
