The correct answer to your question and how to solve it is
The relation between wavelength (λ)and the frequency of electromagnetic oscillation (f) is described by the following expression: λ=c/f, where c–is the speed of light in vacuum = 3*10^8 m/s
Derive f from above: f = c/λ.How to Calculate: λ=890nm = 890*10^-9m = 8.9*10^-7m
f =3*10^8m/s Divided by 8.9*10^-7m = 0.34*10^15 s-1=3.4*10^14 s-1
So your Answer is: The frequency of radiation of wavelength 890 nm is 3.4*10^14s-1
Answer:
40 ms¯².
Explanation:
To solve this problem, we shall illustrate the question with a diagram.
The attached photo gives a better understanding of the question.
From the attached photo:
Velocity (v) = 160 ms¯¹
Time (t) = 4 secs.
Acceleration (a) =?
Acceleration (a) = Velocity (v) /time (t)
a = v/t
a = 160/4
a = 40 ms¯²
Therefore, the initial acceleration of the rocket is 40 ms¯².
The correct answer is: acceleration.
In fact, the slope of the graph of velocity versus time corresponds to the ratio between the variation of v and the variation of t:

But this is exactly the definition of acceleration:

, so acceleration is the correct answer.
A horseshoe magnet has north and south, so does a bar magnet, but with the horseshoe magnet, the whole thing is bent so both ends are the same way. <span />
Answer: well if it isnt moving, then there would not be any potentiol energy. Sothe answer is 0. I hope this helps :) Thank you. Plz mark brainliest.
