Nuclear power refers to the application of nuclear reactions, which discharge nuclear energy to produce heat and is most generally utilized in steam turbines to generate electricity in a nuclear power plant. Nuclear energy can be obtained from nuclear decay, nuclear fission, and nuclear fusion reactions.
The controlled release of nuclear energy in a reactor is attained by controlling the fission without controlling a chain reaction. If a chain reaction occurs, then the amount of energy would increase exponentially, so in order to monitor the release of energy, fission must be controlled without controlling a chain reaction.

Explanation:
Sickle cell anaemia is a recessive disorder in which the blood of the person is not able to clot properly. For sickle cell to occur, both the alleles for the trait have to be recessive. A person who has a dominant and a recessive allele will be heterozygous, showing the dominant characteristics. But such a person will be a carrier for the disease. There will be chances for the offsprings of that person to actually have the disease.
Both have same structure. Eat the same, move the same.
Answer: 0.04metres
Explanation:
The wavelength of a wave is the distance covered by the wave after one complete cycle. It is measured in metres, and represented by the symbol λ
Recall that Velocity (V) = Frequency F x wavelength λ
V = F λ
Make λ the subject formula
λ = V / F
In this case Frequency = 0.4 kHz
Convert kilohertz to hertz by multiplying 0.4 by 1000 i.e (0.4 x 1000Hz) = 400Hz
Velocity of wave = 16 m/s
So, λ = V / F
λ = 16 m/s / 400Hz
λ = 0.04metres
Thus, the wavelength of a wave is 0.04metres
