When is your internal assessment on Modern Physics?
Tuesday 9 of June
Thursday 10 June
Thursday 9 of June
Never! I take no more quizzes because I'm lazy
2
Which of the following is true of proper time?
it is always larger than dilated time
it's measured by an observer at rest w/respect to 2 events
it's measured by an observer moving w/respect to 2 events
it is measured for an object at rest
3
From the perspective of the aliens (travelling at 0.5c), how will they see Sonny Bill Williams?
moving in fast motion
moving at a normal rate
moving in slow motion
as a hero
4
The alien ship flies horizontally at 0.5c. From Tom Brady's perspective, the ship will be:
the same height, but wider
the same height, but thinner
shorter and wider
shorter and thinner
5
A rugby field is 100m long. How long does an alien ship flying at 0.5c observe the field to be?
115.5 m
50 m
86.6 m
100 m
6
Satellites travel at a very high speed, so we (on Earth) measure satellite clocks to run:
fast
slow
backwards
normal... (by now you know it's not this one)
7
How fast must a spaceship travel if it is to become 30% as long as its rest length?
0.999c
0.84c
0.95c
0.30c
8
As an object increases its speed, its mass:
always decreases
remains the same
may increase or decrease
always increases
9
The Michelson-Morley experiment confirmed that:
The speed of light is the same for all observers
The speed of light is constant through the ether
the speed of light is not possible to measure experimentally
The speed of light is ... something
10
The speed of light...
is the same for all observers, regardless of their motion
depends on how fast the observer is moving
will be slower with respect to fast moving objects
is slowest through the vacuum of space
11
Which of the following is FALSE?
The speed of light is the same for all observers
every inertial reference frame is equally valid
In a vacuum, c varies slightly based on light frequency
The laws of physics are the same in all reference frames
12
Which of the following would be considered a non-inertial reference frame?
A man standing on a chair
A cat running down the stairs at constant speed
A volleyball that is in freefall toward Earth
An airplane banking, following a curved path
