Assume that a hydrogen atom is a scale model" of the solar system, and that the electron orbits the proton in a circular orbit with a radius of 1 angstrom (1010 m). you may assume here that the proton is infinitely more massive than the electron. a) find the total energy (kinetic plus potential) of the electron in this orbit. b) using the larmor formula for power radiated by an accelerating electric charge: find the power radiated by the electron. based on your result, comment on the stability of this "classical" atom

An automobile of mass 2000 kg moving at 30 m/s is braked suddenly with a constant braking force of 10000 n. how far does the car travel before stopping?

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
