Question 1

The conversion of mass to energy is measurable only in

Accepted Answer

Nuclear reactions involve changes in the nucleus of an atom, where a small amount of mass is converted into a large amount of energy, as described by Einstein's equation E=mc².

Question 2

The conversion of energy to mass is only in

Accepted Answer

In nuclear reactions, energy can be converted to mass and vice versa, as described by Einstein's equation E=mc².

Question 3

If you add energy to an electron, you can get it to move faster. This can be done using electromagnetic fields. If an electron is given energy in the amount of 220,000 eV (an electron volt unit of energy)it can reach speeds of 2.70 × 10⁸ m/s. At this speed what would the mass of an electron be? An electron has a rest mass of 9.109 × 10^-28 g.

Accepted Answer

At high speeds, close to the speed of light, the relativistic mass of an electron increases. Using the relativistic mass formula, m = m0 / sqrt(1 - v^2/c^2), where m0 is the rest mass, v is the velocity, and c is the speed of light, the mass increases to approximately 2.10 × 10^-27 g.
