Answer:
1.63103 seconds
Explanation:
= Actual period of clock = 1 second
v = Speed at which the observer is moving = 0.79 c
c = Speed of light =
Time dilation is given by
The period is 1.63103 seconds

a)
The volume of the sports hall can be calculated using the equation
where
a, b, c are the measures of the sizes of the hall
For the sport hall in this problem, we have
a = 80 m
b = 40 m
c = 15 m
Substituting into the equation, we find
b)
Being a gas, the air fills the whole sport halls, therefore its volume is equal to the volume of the sports hall.
The relationship between the mass, the volume and the density of the air is
where
is the density
m is the mass
V is the volume
Here we have:
Solving for m, we find the mass of air:
Answer:
61578948 m/s
Explanation:
λ = λ
687 = 570
= 61578948 m/s
So Slick Willy was travelling at a speed of 61578948 m/s to observe this.
