Ham radio operators often broadcast on the 6-meter band. The frequency of this electromagnetic radiation is MHz. [speed of light
Volgvan

Answer:

50 MHz

Explanation:

The relation between frequency and wavelength is shown below as:

c=frequency\times Wavelength

c is the speed of light having value 3\times 10^8\ m/s

Given, Wavelength = 6 m

Thus, Frequency is:

Frequency=\frac{c}{Wavelength}

Frequency=\frac{3\times 10^8}{6}\ Hz

Frequency=50\times 10^{6}\ Hz

Also,

Also, 1 Hz = 10^{-6} MHz

So,<u> Frequency = 50 MHz.</u>

Nucleotides are the organic molecules which serve as monomer units for the formation of nucleic acid polymers which are the deoxyribonucleic acid and the ribonucleic acid (RNA) and both are the essential biomolecules within the life on the Earth.

Nucleotides are building blocks of the nucleic acids. They are the molecules which are composed of three sub units which are:  

  • Nitrogenous base which is also called as nucleobase
  • Five-carbon sugar  which can be ribose or deoxyribose
  • At least one phosphate group which is attached to the sugar.

Each marking is for 1.

It is the most accuracy possible as there is no smaller marking.

Significant figures expresses the required amount of accuracy.

Thus the volume indicated from the diagram is 71 .
