Question

Problem 3. The Twins Paradox.

**Question 1. Which basic principle of Special Relativity
is used that makes the Theory appear to fatally contradict
itself?**

a. the laws of physics are the same for all non-accelerated observers

b. the speed of light in vacuum is a constant regardless of the motion of the observer or the source

c. the laws of physics are the same for all accelerated observers

d. a and b

**Question 2. What is the resolution of the paradox in
terms of what the spacefaring twin experiences that the Earthbound
twin does not.**

a. the spacefaring twin is moving while the Earthbound twin is not

b. the spacefaring twin exceeds the speed of light in vacuum

c. the spacefaring twin experiences acceleration that the Earthbound twin does not

d. the Earthbound twin experiences acceleration that the spacefaring twin does not

e. none of the above

**Question 3. The Special Theory of Relativity
covers:**

a. only nonaccelerated conditions

b. only accelerated conditions

c. both accelerated and nonaccelerated conditions

d. neither accelerated or nonaccelerated conditions

Answer #1

Question 1 Answer. Option a is correct. Laws of physics are invariant in all non-inertial frames.

In paradox taking the Earth as stationary frame, the spaceship is moving. So, the age of spaceship twin will be lowered than the Earth twin. But taking the space ship as stationary, now Earth is moving in opposite direction. So, age of the Earth twin is less than spaceship twin.

Question 2 Answer. Option C is correct.

Considering the ship as usual so,when ship is achieving speed it will be accelerated. But taking a hypothetical example that ship achieves it's speed in infinitesimal time or that is it is not accelerated, than option e is correct.

Question 3 Answer . Option a is correct.

Special relativity is only applicable to non-accelerated frames (non-inertial frames).

Question 6: Relativity
a. How does the speed of light in a vacuum change when observed
from a frame of reference that is accelerating versus a frame of
reference that is moving at a constant velocity?
b. Which frames of reference can be studied using special
relativity?
c. A stationary observer measures the lengths of two identical
objects that are traveling at nearly the speed of light. Write 2 –
3 sentences explaining how the measurements can be used to...

For each questions, please show me all your work and explain the
answer.
1. A rocket is moving at 1/4 c relative to Earth. At the center
of this rocket, a light source suddenly flashes. To an observer at
rest in the rocket
a. the light pulse will reach the front of the rocket at the
same instant that it reaches the back of the rocket.
b. the light pulse will reach the front of the rocket before it
reaches...
