The radiation that was emitted is still "visible"
The universe is still expanding
Dark matter could only be crated by an atomic collapse big enough to create or destroy a universe
Answer:
He sees the light as 1c
Explanation:
According to relativity, the speed of light is the same in all inertial frame of reference.
If we were to add the velocities as applicable to a normal moving bodies, the relative speed of the light beam will exceed c which will break relativistic law since nothing can go past the speed of light.
Answer:
C. Try an element in the same group as lithium.
Explanation:
Answer:
6 km
Explanation:
speed of Aaron, v = 8 km/hr
speed of Sam, v' = 6 km/hr
time 15 min = 0.15 hr longer than the other
Let the distance covered by both of them is d.
Let the time taken by Aaron is t and the time taken by Sam is t + 0.25
use the formula of distance = speed x time
For Aaron:
d = 8 x t ..... (1)
For Sam:
d = 6 ( t + 0.25) ..... (2)
From (1) and (2)
8 x t = 6 (t + 0.25)
8 t = 6t + 1.5
2t = 1.5
t = 0.75 hour
So, the distance traveled by both is 8 x 0.75 = 6 km.
