Answer: 100 m
Explanation:
Initial speed(u) = 40 m/s
Final speed(v) = 0 m/s
Acceleration = v-u/t
=> 0-40/5
=> 8 m/s^2
Displacement= s
=> 2as = v^2-u^2
=> 2(-8)(s) = 0 - (40)^2
=> -16s = -1600
s = 100 m
We can say the vehicle move 100 meters before stopping.
Answer:
The angle of reflection is "60°".
Explanation:
The given values are:
Light from monochromatic source,
= 560 nm
Angle of incidence,
= 60°
Surface of fused quartz (n),
= 1.56
Whenever a light ray was indeed occurring at a flat surface, it should be the law or concept of reflection which contains this same rays of light, the reflected ray as well as the "normal" ray at either the mirror surface.
According to the above law,
⇒ 
then,
⇒ 
Relative time is the physical subdivision of the rocks found in the Earth's geology and the time and order of events they represent. Absolute time is the measurement taken from the same rocks to determine the amount of time that has expired
Explanation:
The uniform microwave radiation remaining from the Big Bang.
So, your body is always having background radiation and that means space!
