hi friend the earth spin at 1,000 in meters per hour
I hope it helped you
For the total internal reflection of a substance, we can express the relationship between the critical angle,
, and the indices of refraction as
(1) <span>
</span>
where
and
are the indices of refraction. And under polarization, we can express Snell's Law as
Rearranging this we have
(2)Substituting equations (1) into (2), we have
Substituting the value of the critical angle, we have
Answer: 33.79°
Answer:
105000km
Explanation:
Given parameters:
Speed of shuttle = 21000km/hr
Time of travel = 5hrs
Unknown:
The distance covered by the space shuttle;
Solution:
Distance is the length of the path traveled.
Distance = speed x time
Input the parameters and solve;
Distance = 21000km/hr x 5hrs
Distance = 105000km
Answer:
- Mirrors offer different levels of reflections for different wavelengths of light.
- For the use of ultra fast pulsed lasers.
- Light can be polarized or unpolarized.
Assuming that the collision is inelastic that is they are stuck together after the collision, momentum is conserved. We can determine the final velocity of the final mass as follows:
m1v1 + m2v2 = m3v3
100(4) + (200)(-3) = (300)v3
v3 = -0.6667 m/s
Therefore, the final mass moves at 0.6667 m/s to the left.
