Question

A long, narrow stick that is moving with a velocity that is perpendicular to its length

is shorter than a similar stick that appears stationary
is longer than a similar stick that appears stationary
is the same length as a similar stick that appears stationary
may be longer or shorter than a similar stick that appears stationary depending on the diretion of travel.
2) A long, narrow stick that is moving with a velocity that is parallel to its length

is shorter than a similar stick that appears stationary
is longer than a similar stick that appears stationary
is the same length as a similar stick that appears stationary
may be longer or shorter than a similar stick that appears stationary depending on the diretion of travel.
3) If two events appear at the same place and time in in a moving reference frame

the events must appear at different places in a reference frame at rest.
the events must appear at different times in a reference frame at rest.
the events must appear at both different times and different places in a reference frame at rest.
the events must appear at the same place and time in a reference frame at rest.
4) In Example R-2 the author shows that the length of a railroad car that is 40m when stationary could be 24 m when moving. How fast would it have to be moving to have a length of 24m?

80cm/sec
80m/sec
80,000,000m/sec
200,000,000m/sec
240,000,000m/sec
320,000,000m/sec
800,000,000m/sec
5) An object has a mass of 1gram and a momentum of 240000.00 kg m/sec when calculated using the standard formula we learned in Chapter 8. What is the momentum of the object when relativity it taken into account?

536656.3 kg m/sec
666666.7 kg m/sec
400000.0 kg m/sec
320000.0 kg m/sec
6) At Fermilab, they collide protons and anti-protons together head on. The protons and anti-protons have the the same mass and the magnitudes of their momentum is the same but in opposite directions. What is the total mass of all of the particles that can result from this collisions?

1/2 the mass of the proton.
twice the mass of the proton.
four times the mass of the proton.
eight times the mass of the proton.
the possible mass is infinite.
7) We often see the formula written, E=mc2. For that formula to be true, it implies

the momentum of the particle involved is zero
the mass of the particle involved is zero
the particle must be moving at close to the speed of light.
the mass of the particle is much greater than the mass of a proton
8) Two wads of putty collide and stick together. The final mass of the combined wad of putty is

greater than the sum of the two individual masses.
less than the sum of the two individual masses.
equal to the sum of the two individual masses
can be either less than or greater than the sum of the two individual masses.
9) Absolute motion

can be determined by calculating the proper length.
can be determined by calculating the proper time.
can be determined by calculating the absolute mass.
can not be determined.
10) The proper time interval

is the smallest possible interval between two events.
is the largest possible interval between two events.
can not be determined.
is the same for all events withint a particular frame of refernce.

is longer than a similar stick that appears stationary
