Answer:
The wavelength of wave is 7.5 meter.
Given:
Speed of wave = 1500
Frequency of wave = 200 Hz
To find:
Wavelength of wave = ?
Formula used:
Where = wavelength of the wave
v = speed of wave
n = frequency of wave
Solution:
Wavelength of wave is given by,
Where = wavelength of the wave
v = speed of wave
n = frequency of wave
= 7.5 m
The wavelength of wave is 7.5 meter.
Mutation is the process by which the gene in the nucleotide suddenly changes its position
Any change in the structure of a gen or in the usual DNA sequence of a cell is called mutation. It can be caused by mistakes during cell division when the DNA is copied or by the exposure to DNA damaging agents in the environment like UV light or cigarette smoke, and may be transmitted to subsequent generations.
A mutation is a permanent alteration of the nucleotide sequence of an organism, virus or other genetic elements.
There are three types of mutations:
- Base substitutions
- Deletions
- Insertions
The Deoxyribonucleic acid, also called DNA, is the hereditary material that carries genetic information for the development and functioning of humans and almost all other organisms. DNA is made of nucleotides.

Answer:
External force on him will be 112 N
Explanation:
We have given the mass of the sprinter m =70 kg
Acceleration of the sprinter
We have to find the net external force
According to second law of motion force = mass ×acceleration
Force is dependent on the mass and acceleration
So
So external force will be 112 N
