Using the given charge-to-mass ratios for electrons and protons, and knowing the magnitudes of their charges are equal, what is the ratio of the proton's mass to the electron's? (Note that since the charge-to-mass ratios are given to only three-digit accuracy, your answer may differ from the accepted ratio in the fourth digit.)
The mass of a theoretical particle that may be associated with the uni?cation of the electroweak and strong forces is (a) How many proton masses is this? (b) How many electron masses is this? (This indicates how extremely relativistic the accelerator would have to be in order to make the particle, and how large the relativistic quantity (would have to be.)

Raymond Davis Jr.’s neutrino detector contained approximately 1030 chlorine atoms. During his experiment, he found that one neutrino reacted with a chlorine atom to produce one argon atom each day. A. How many days would he have to run the experiment for 1% of his tank to be filled with argon atoms? B. Convert your answer from A. into years. C. Compare this answer to the age of the universe, which is approximately 14 billion years (1.41010y) . D. What does this tell you about how frequently neutrinos interact with matter?
What is the Standard Model? Express your answer in terms of the four fundamental forces and exchange particles.
A 50.0-g piece of aluminum has a net charge of +4.20 C. Aluminum has an atomic mass of 27.0 g/mol, and its atomic number is 13. a. Calculate the number of electrons that were removed from the initially neutral aluminum to produce this charge. b. Determine what fraction of the original number of electrons this removed number represents. c. By how much did the original mass of the aluminum decrease after charging?

In the simple Bohr model of the ground state of the hydrogen atom, the electron travels in a circular orbit around a fixed proton. The radius of the orbit is 5.281011m , and the speed of the electron is 2.18106m/s . The mass of an electron is 9.111031kg . What is the force on the electron?
List all the possible values of s and msfor an electron. Are there particles for which these values are different? The same?
Nobel laureate Richard Feynman (19181088) once said that if two persons stood at arms length from each other and each person had 1% more electrons than protons, the force of repulsion between them would be enough to lift a weight equal to that of the entire Earth. Carry out an order-of-magnitude calculation to substantiate this assertion.
Models are particularly useful in relativity and quantum mechanics, where conditions are outside those normally encountered by humans. What is a model?
Suppose Earth and the Moon each carried a net negative charge Q . Approximate both bodies as point masses and point charges. (a) What value of Q is required to balance the gravitational attraction between Earth and the Moon? (b) Does the distance between Earth and the Moon affect your answer? Explain. (c) How many electrons would be needed to produce this charge?
