b
Explanation:
From the question we are told that
The speed of the spaceship is
Here c is the speed of light with value
The length is
The distance of the star for earth is
The speed is
Generally the from the length contraction equation we have that
Now the when at rest the length is
So
Considering b
Applying above equation
Here
So
Answer:
Detailed solution is given below
Answer
given,
D = 50 mm = 0.05 m
d = 10 mm = 0.01 m
Force to compress the spring
F = 3160 N
stress correction factor from stress correction curve is equal to 1.1
now, calculation of corrected stress
= 442.6 Mpa
The tensile strength of the steel material of ASTM A229 is equal to 1300 Mpa
now,
since corrected stress is less than the
hence, spring will return to its original shape.
