This mathematical model describes the changes that occur in a sample of water as its temperature increases. based on this model, how do you expect the motion of the molecules in ice to compare with the motion of molecules in water vapor?

a. i expect the molecules in ice to move more quickly than the molecules in water vapor.
b. this model does not provide enough data to answer the question.
c. i expect the motion to be very similar.
d. i expect the molecules n water vapor to move more quickly than the molecules in ice.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc

Which of the following is a true statement about the acceleration ~a of the pendulum bob ~a is equal to the acceleration due to gravity. ~a is perpendicular to the bob’s trajectory. ~a is equal to the instantaneous rate of change in velocity. ~a is tangent to the bob’s trajectory.

Aflute player hears four beats per second when she compares her note to a 523 hz tuning fork (the note c). she can match the frequency of the tuning fork by pulling out the “tuning join” to lengthen her flute slightly. what was her initial frequency?
