Answer:
The answer is a," their receptors are sensitive to chemical molecules."
Answer: you are the person in charge of building a nuclear power plant in Florida. your first choice is to select a site for building the power plant.
Explanation: To find the answer, we need to know more about the nuclear power plants and the criteria to select the site for power plant.
<h3>
What you mean by nuclear power plants?</h3>
- Nuclear power can be defined from the nuclear fission reaction.
- These power plants will heat the water to produce steam and this steam is used to spin large turbines and thus generates electricity.
<h3>How to select the site for nuclear power plant?</h3>
- We have to consider the following things,
- keep distance from populated area.
- distance from load center.
- Accessibility to site.
- Water availability and fuel availability.
- waste disposal.
Thus, we can conclude that, before building a nuclear power plant, our first choice should be to select a site.

Answer:
Revolutions made before attaining angular velocity of 30 rad/s:
θ = 3.92 revolutions
Explanation:
Given that:
L(final) = 10.7 kgm²/s
L(initial) = 0
time = 8s
<h3>
Find Torque:</h3>
Torque is the rate of change of angular momentum:
<h3>Find Angular Acceleration:</h3>
We know that
T = Iα
α = T/I
where I = moment of inertia = 2.2kgm²
α = 1.34/2.2
α = 0.61 rad/s²
<h3>
Find Time 't'</h3>
We know that angular equation of motion is:
ω²(final) = ω²(initial) +2αθ
(30 rad/s)² = 0 + 2(0.61 rad/s²)θ
θ = (30 rad/s)²/ 2(0.61 rad/s²)
θ = 24.6 radians
Convert it into revolutions:
θ = 24.6/ 2π
θ = 3.92 revolutions
Electricity moves so quickly that it can only be there for so long.
