Answer:
85.62 m
168.75 years
101.04 years
Explanation:
= Length of ship = 143 m
v = Velocity of ship = 0.8c
c = Speed of light
s = Distance to Boralis orbit = 135 ly
Gamma value
Length contraction is given by
The length is 85.62 m
Time taken
Time taken from the perspective one Earth is 168.75 years
Time dilation is given by
The time taken from the perspective of the ship is 101.04 years
The weight of the automobile is 17,533.6 N.
<h3>
Weight of the automobile</h3>
The weight of the automobile is calculated as follows;
P = F / A
F = (W/4)
P = (W/4) / A
P = W/4A
W = 4AP
where;
W = (4)(217 x 10⁻⁴ m²)(2.02 x 10⁵ Pa)
W = 17,533.6 N
Thus, the weight of the automobile is 17,533.6 N.
