Answer:
It is a type of map used to map out the geographical change over time. I believe
Explanation:
The frequency of a beam of light does not change as it passes from a medium to another, only its wavelength and speed are affected. The experimental speed of light in air is:
3 * 10^8 m/s
Therefore, the frequency of this beam of light is:
v = fλ; where v is speed, f is frequency, and λ is the wavelength. The frequency thus is:
3×10⁸ / (670 × 10⁻⁹) = 4.48 × 10¹⁴ Hz
The frequency will remain the same in the solid medium
The speed will then become:
4.48 × 10¹⁴ × 420 × 10⁻⁹ = 1.88 × 10⁸ meters per second
Answer:
1/8
Explanation:
17,100 years is 3 times the half-life of 5,700 years. After each half-life, half remains, so the amount remaining after 3 half-lives is ...
(1/2)(1/2)(1/2) = 1/8
1/8 of the sample remains after 17,100 years.
All electromagnetic waves travel at
299,792,458 meters per second
in vacuum.
Answer:
Right
Explanation:
Because of the Coriolis effect, surface ocean currents are deflected to the Right of their path of motion in the Northern Hemisphere.
Since the Earth is revolving on its axis, flowing air in the Northern Hemisphere are deflected to the right and in the Southern Hemisphere to the left. The consequence of Coriolis is called this deflection.
