<span>Whatever the focus of the experiment is, plus any others factors that might influence the outcome of the experiment. If you are testing a new cancer drug, the experimental group and the control group must both be people with the same type of cancer, and both be a representative distribution of the population, all races, genders, ages, etc. You want the only difference in the two groups to be what you are studying, i.e. the effects of the drug.</span>
Base on your diagram it is a Series-Parallel type of connections right? So based on my calculation and the rule in computing the resistance and voltage of a parallel and series. The total resistance is 1.25 and the total voltage is 2.04 V
Answer:
because if not then you wont be able to properly document the change happening in your experiment
Explanation:
The human population which grows by about 2 percent each year, is showing linear growth.
<h3>What is linear increment?</h3>
A linear increment occurs when a sequence increases gradually with a constant value.
If a population increases at the rate of 2%, the incremental rate or constant factor is 2%, thus, we can conclude that the human population which grows by about 2 percent each year, is showing linear growth.

The electric charge on surface is 2.66×10-⁹NC
<h3>What is an electric charge?</h3>
The electric charge is the property of subatomic particle that causes it to experience a force when placed in an electric and magnetic field.
We have given ,
Electric field= 1.5×10⁴N/C
Radius = 4cm = 0.04m
E = k× q/ r²
1.5×10⁴×16×10-⁴/9×10⁹=q
q= 2.66×10-⁹C
