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
Power is the scientific term defined as the rate at which
work is accomplished. Power can be seen everywhere as it is applied to our
everyday living. Power is seen when one pushes a heavy cart. It could be seen
when a baseball hitter hits the ball.

F(g)= Gm1m2/ r^2
If mass is increased, so will the force of gravity because it is in direct relationship with the gravitational force, but if distance is increased, the force of gravity will decrease because it is indirectly related ( since it is on the bottom of the equation)
Rutherford's model of the atom (ESAAQ) Rutherford carried out some experiments which led to a change in ideas around the atom. His new model described the atom as a tiny, dense, positively charged core called a nucleus surrounded by lighter, negatively charged electrons.
Answer:
12 km/h
Explanation:
Average Speed = Distance / Time (or rate)
Pick a point on the graph for Ian and plug in values.
For example, 20 minutes -> 4km
Hence, Average speed = 4km ÷ 20 minutes = 0.2 km/min
0.2 km/min × 60 = 12 km/h
