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?

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
