An evacuated tube uses a potential difference of ΔV = 0.58 kV to accelerate electrons, which then hit a copper plate and produce X-rays.

Write an expression for the non-relativistic speed of these electrons v in terms of e, ΔV, and m, assuming the electrons start from rest.

Calculate the non-relativistic speed of these electrons v in m/s.

The temperature near the center of the Sun is thought to be about 15 million degrees Celsius, that is, 1.5 × 107 °C.

Through what voltage, in volts, must a singly charged ion be accelerated to have the same energy as the average kinetic energy of ions at this temperature? Assume the gas inside the sun is monatomic.
