Your teacher is right. The moon can be seen early in the morning sometimes and late at night. Different phases are only visible on certain days as one day might be full quarter, the next full moon, the next first quarter, etc.
The answer to this question is B I think
Velocity = fλ
where f is frequency in Hz, and λ is wavelength in meters.
2.04 * 10⁸ m/s = 5.09 * 10¹⁴ Hz * λ
(2.04 * 10⁸ m/s) / (5.09 * 10¹⁴ Hz ) = λ
4.007*10⁻⁷ m = λ
The wavelength of the yellow light = 4.007*10⁻⁷ m
What are the answers to choose from
Answer:
Explanation:
Given:
Initial Velocity, u = 0 km/s (at rest)
Final Velocity, v = 16 km/s
Time taken, t = 3 sec
acceleration, a = (v - u)/t
= (16 - 0)/3
= 5.33 km/s^2
