Explanation:
Cons
- Nuclear energy is very unsafe compared to other energy sources. A leakage or explosion can release dangerous radioactive elements from the plant causing lethal mutations on the organisms in the ecosystems.
- Nuclear energy use produces nuclear waste that needs to be stored safely to avoid contaminating the environment. Finding a safe place to store the waste and how to contain the waste over 1000s of years is very costly and challenging.
Pros
- Nuclear energy is very clean energy because it releases no greenhouse emissions into the atmosphere that may cause global warming.
- Its is a cheap form of energy because it releases a lot of energy relative to the investment.

Answer:
0.1 N
Explanation:
Considering the relationship between force,
spring constant and extension as defined by Hook's law
The force F=xk as from Hooke's law where F is the force of the spring, k is spring constant and x is extension or compression. Substituting 2 N/m for k and 5cm which is equivalent to 0.05 m for extention x then the force will be
F=2*0.05=0.1 N
After the second car starts out,
D = 30 + 110 H
360 = 30 + 110 H
330 = 110 H
H = 330/110
H = 3 hours after the second car leaves.
That's 3.5 hours after the first car leaves.
