Question

two predictions of special relativity are time
dilation and length contraction. describe each of these
effects

Answer #1

Answer each of the following questions in one paragraph.
If you want/need, you can supplement your written explanation with
diagrams or equations.
1. Provide an example of an inertial frame of reference and a
non-inertial frame of reference. Explain the difference.
2. Using the Michelson-Morley experiment as an example, explain
why classical mechanics was unable to explain natural
phenomena.
3. Using at least one of Einstein's "thought-experiments",
explain how special relativity addresses how it is possible for
observers in two...

Answer the following questions about Einstein's theory of
special relativity:
a) Describe the assumptions of this theory and ask me how I
can observe the time and space in a system that is uniform in
velocity (v). I'm at a standstill
b) If the car approaches me at a speed (v) while sending a
horn (vibrate f1) and a headlight (f2), find out the two
frequencies observed by me.

Derive the Lorentz-Fitzgerald contraction from the Principle of
Relativity by requiring the longitudinally oriented light clock
(where the light pulses travel in the direction of motion) to agree
with the transverse light . A clock’s rate should be independent of
orientation, otherwise there is a “special direction” in space.
Part of the Principle of Relativity is that all spatial directions
are equivalent in their properties. (Note if the two clocks
disagree, then one could detect one’s motion through the ether,...

It is fairly easy using basic special relativity to arrive at
the conclusion that the magnetic force effect on nearby charges of
wires carrying currents on nearby charges is only due to the length
contraction in certain inertial frames from the point of view of
charges, which gives rise to a perceived change in charge density.
However, we structure the (classical field) laws of
electromagnetism in Maxwell's laws using a B field.
My question is, is it possible to formulate...

Special Relativity:
A and B are initially a distance L apart, at rest with respect
to each other. At a given time, B accelerates toward A with
constant proper acceleration a. Assume aL << c^2.
a.) Working in A's frame, calculate the difference in readings
on A's and B's clocks when B reaches A.
b.) Do the same by working in B's frame, and show that the
result agrees (neglecting higher-order effects) with the result
from a.).

An athlete knows that if a time interval on a moving spacecraft
is measured from Earth the time will be greater than would be
measured on the spacecraft. They propose to set a world record 100
m dash time by having the time measured by an observer on a moving
spacecraft. (The race will still take place on Earth.) Will this
plan work? Provide a mathematical justification.

Describe the neuronal control of skeletal muscle contraction and
explain the effects of calcium channel blockers on blood pressure.

What is true in Einsteins SPECIAL RELATIVITY, choose one of the
three alternatives each for a) - d)
a) EVENTS (1. Are affected by our choice of reference frame - 2.
Defines spacetime - 3. Only has one set of coordinates in space and
time)
b) WRISTWATCH TIME MEANS (1. The time you measure in your own
reference frame - 2. The time measured by an observer for an
arbitrary object - 3. That relativistic affects only impacts
watches and...

Special Relativity: Consider a firecracker that after being
triggered explodes after 1 second. An observer A is standing some
distance away from observer B who is traveling with constant
velocity towards A with the firecracker. The velocity of B and
distance between A and B is such that B will reach A in 1 sec as
measured by A. At this instant B triggers the firecracker they are
holding. Which of following options is correct?
The firecracker explodes exactly when...

How much time does a meter stick moving at 0.100c relative to an
observer take to pass the observer? Assume the meter stick lies
parallel to its direction of motion and give an answer to at least
3 decimal places.
Reminder: c = 3 X 10^8 m/s, the speed of light
