Answer:
A and B
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value 
Thus, the product of the wavelength and the frequency is constant and equal to
<u>Option A is correct.</u>
Given, Frequency = 
Thus, Wavelength is:
Also, 1 m = 
Å
So,
<u>Wavelength = 3.0 Å</u>
<u>Option B is correct.</u>
As stated above, the speed of electromagnetic radiation is constant. Hence, each radiation of the spectrum travels with same speed.
<u>Option C is incorrect.</u>
Answer:
Period of the signal.
Explanation:
So, this question is all about a concept in physics or astronomy which is called or known as Radiation Astronomy and Galactic Nuclei that are active. This concept talks most about Quasars; a powerful radiating object which derives its power from black holes.
When You take a look at Quasars, we get the to know that the more you think you can see, the more they move away from us.
Thus, when "You are observing the radiation from a distant active galaxy and you notice that the amplitude of the signal varies in strength regularly over a certain period. The maximum possible size for the source of this radiation can now be calculated from the "PERIOD OF THE SIGNAL.
NB: not the amplitude but the period.
200n because it's 2×5=10so maybe try solving the problem like that ok does that help
Answer:
Kinetic energy is energy an object has because of its motion. A ball held in the air, for example, has gravitational potential energy. If released, as the ball moves faster and faster toward the ground, the force of gravity will transfer the potential energy to kinetic energy.
Explanation:
there hope this helps
Answer:
A falling object will continue to accelerate to higher speeds until they encounter an amount of air resistance that is equal to their weight.
