Compare a bound electron that executes harmonic oscillations at an angular frequency of w 1015 rad/s with a 0.5 kg mass oscillating at a frequency of w/2π 1.0 hz. (a) what are the ground state energies in each case? express your answers in ev (electron volts) (b) compute the amplitude of oscillation in classical mechanics that gives the ground state energy in quantum mechanics. carry out the computation for each case in turn. comment on the physical significance of the results, e. g., in what way do the numbers you obtain make (or not make) physical sense?

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
