Abrave student is attempting to come to class in a car weighing 2,200 pounds and driving at 140 mph (the end of the speedometer) so he can be on time. calculate the wavelength of the car at the top speed of 140 mph. why would you not wish to use wave mechanics to describe the motion of a particle such as this?

Explanation:

Given

weight of car

Velocity of car

Energy conservation

where h=planck constant

Now wavelength

We do not use the wave mechanics because the size of the particle and wavelength are not comparable.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
