Answer:
This question is asking to find the average speed during the dive. The answer is 22m/s.
Explanation:
Average speed of a substance can be calculated knowing it's distance over a particular amount of time.
The formula for average speed is:
Average speed (s) = Distance (d) / time (t)
In the case of this question where A peregrine falcon dives 176 meters through the air in 8 seconds, the distance of the falcon is 176m, while the time is 8s. Hence;
Average speed = 176/8
Average speed = 22
Therefore, the average speed of the falcon diver is 22m/s.
An atom has a net zero electric charge if the number of protons and electrons it contains are the same.

<u>Answer:</u>
<u>For a:</u> The wavelength of light is 
<u>For b:</u> The light is getting absorbed
<u>Explanation:</u>
To calculate the wavelength of light, we use Rydberg's Equation:

Where,
= Wavelength of radiation
= Rydberg's Constant = 
= Higher energy level = 7
= Lower energy level = 3
Putting the values in above equation, we get:

Hence, the wavelength of light is 
There are two ways in which electrons can transition between energy levels:
- <u>Absorption spectra:</u> This type of spectra is seen when an electron jumps from lower energy level to higher energy level. In this process, energy is absorbed.
- <u>Emission spectra:</u> This type of spectra is seen when an electron jumps from higher energy level to lower energy level. In this process, energy is released in the form of photons.
As, the electron jumps from lower energy level to higher energy level. The wavelength is getting absorbed.
Answer: Option (c) is the correct answer.
Explanation:
Backbone in a nucleic acids strand is made up of sugar molecules attached with phosphodiester bond.
This sugar-phosphate linkage helps in joining of nucleotides in a DNA sequence. Due to this backbone structural framework of nucleotides is formed. In DNA, the sugar is deoxyribose.
Thus, we can conclude that the backbone in a nucleic acids strand is called sugar backbone.
