Answer:

3) they lose energy at a varying rate - is the correct answer.

Radioactive decay is defined as the process by which an unstable atomic nucleus loses its energy by emitting radiations. The decay is random and cannot be predicted earlier.

Answer:

1)  They release energy.

Explanation:

The radioactive decay of chemical elements is a phenomenon in which the unstable nucleus of an atom disintegrates becoming a more stable nucleus, but due to the decay, particles such as alpha and beta particles among others are released.

A Radioactive decays releases energy (it is important to remember that energy is not created or destroyed, only transformed), in order to move from a non-stable nucleus to a more stable one.

The radioactive decay has an exponential decay, which means that it is reduced steadily over time, and this depends on the element.

The statemente that best describes what happens to elements during radioactive decay is: 1)  They release energy.

if there are 500 people in a population, and 150 are homozygous HbA/hba, 150 are homozygous hbs/hbs, and 200 are heterozygous hb
sineoko [7]

Answer:

0.547

Explanation:

Given -

Total Population - 500

Individuals with homozygous HbA/hbA genotype - 150

Individuals with homozygous hbs/hbs genotype -150

Individuals with heterozygous hba/hbs genotype -  200

Let us assume the given population is in Hardy Weinberg' equilibrium

The frequency of individuals in the given population with homozygous HbA/hba genotype is equal to number of individuals with homozygous HbA/hba genotype divided by total population.

\frac{150}{500} \\= 0.3

The frequency of hba allele is equal to

\sqrt{0.3} \\= 0.5477

what is the force needed to move a boy and his wheelchair with a combined mass of 30kg at 0.4 meters per square second
vichka [17]

Answer:

The force needed to move a boy and his wheelchair with a combined mass of 30kg at 0.4 meters per square second is 12 newton.

Explanation:

  • According to Newton's second law based motion "the moving object's acceleration is based upon two terms - one is the total force acting upon that object and the other one is the net mass of the object."
  • In mathematical term, F=ma. where F= force, m= mass, a= acceleration.
  • So, by performing the calculation, \bold{\mathrm{F}=30 \times 0.4 \mathrm{N}=12 \mathrm{N}}
  • 12N force will move the boy along with the wheel chair.
