What is the spring constant of a bow and
arrow where the archer must apply 240 N of force to pulls the string back
0.45 m? (Show your work!)
What is the frequency of the pulses from
a light that blinks once every 40 ms? (Don’t forget to convert. Show
If microwaves have a frequency around 9.00
x 10^9 Hz and travel at the speed of light (3.00 x 10^8 m/s), what is their
wavelength? (Show your work!)
Look at this diagram:
______ How many wavelengths are there?
______ Is this a pulse wave? (Yes or No)
______ Is this a transverse or longitudinal wave?
Why is the velocity greatest at the equilibrium
Why not before it?
Why not beyond it?
What three things do we disregard when
talking about a pendulum?
For a pendulum in motion:
Where is the acceleration greatest? (At the equilibrium point or at the ends?)
Where is the velocity greatest? (At the
equilibrium point or at the ends?)
Why does an acrobat swing past the equilibrium
position when there is no force acting on her at that point?
If two waves, one with an amplitude of
0.55 m and the other with an amplitude of 0.30 m, are interacting in the
same medium, what would be the resulting amplitude if they constructively
interfered with one another?
If a 7.0 m long rope is stretched and vibrated,
what would be the wavelengths if the vibration resulted in the creation
of 4 nodes? (Include a diagram with your explanation and show your work.)
