Answer:
The maximum magnetic force is 2.637 x 10⁻¹² N
Explanation:
Given;
Power, P = 8.25 m W = 8.25 x 10⁻³ W
charge of the radiation, Q = 1.12 nC = 1.12 x 10⁻⁹ C
speed of the charge, v = 314 m/s
area of the conecntration, A = 1.23 mm² = 1.23 x 10⁻⁶ m²
The intensity of the radiation is calculated as;
The maximum magnetic field is calculated using the following intensity formula;
The maximum magnetic force is calculated as;
F₀ = qvB₀
F₀ = (1.12 x 10⁻⁹) x (314) x (7.497 x 10⁻⁶)
F₀ = 2.637 x 10⁻¹² N
Answer:
The main reason why the magnetic field lines do not cross each other is because of the resultant force (the single force) on a north or south pole at any one point on earth can only be in one direction...
Explanation:
This means that if you were to have a compass it needle cannot be showing two different directions. THIS MEANS THAT THE MAGNETIC FORCES ACTING FROM POLE TO POLE ACTS ONLY IN ONE DIRECTION, NOT 2

The law of conservation of energy supports climate change research because the energy we use is released into the atmosphere, creating loop of continual absorption and releasing of heat.
<h3>Law of conservation of energy</h3>
The law states that energy can neither be created nor destroyed but can always be converted from one form to another.
In light of this, any energy used by humans or natural processes is not destroyed. Instead, they are converted into another form or released into the atmosphere.
In the atmosphere, absorption and release of heat energy by greenhouse gases and irradiation create a loop. This loop causes a net heating or cooling of the planet, a phenomenon that affects the climate.

I believe the correct answer from the choices listed above is the second option. In a nuclear power plant, nuclear energy is first changed to thermal energy. Heat energy is first given off in this process. Hope this answers the question. Have a nice day.
