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:
B. 85 V
Explanation:
E(rms) = E(peak-to-peak) / squareroot(2)
E(rms) = 120V / 1.414 = 84.9 V
(When rounded) = 85 V
Answer:
(B) 0.06W
Explanation:
power absorbed by the resistor is given by
Where V = voltage
R= resistance
I = current through the circuit
we have given V =12 Volt and resistance =2.4 K
current
power using voltage and resistance equation
=0.06W
using current equation = 0.06W
Answer:
The amplitude ( ) of a wave is the distance from the centre line (or the still position) to the top of a crest or to the bottom of a trough . Be careful with this quantity - the centre line is not always given in a diagram.
Explanation:
E = hf, and h is the Planck's constant. When larger frequency is needed, more energy will also be needed. Since the blue light has the higher frequency, it would be the<span> level X to Y's transition which is the one that has the highest energy difference.
