Cases A and B are all correct.
In Case C, the GPE is incorrect.
(But then, the power and HP have been correctly calculated
from the incorrect value of GPE, so we can't gig you too bad.)
Answer:
The health hazard of directly going to these places to take direct readings and observations.
Explanation:
The Chernobyl accident was a catastrophic radioactive accidents, with an immediate fatal effect on some victims (mostly firemen and law enforcement officers). Scientists investigating the effects of the radiation left on the venues of the accident face a health risk if they intend to carry out a full scale on-field testing and experiment. Some of the relocated occupants of these places, that have long been relocated, have shown some health effect of the radiation. And scientist studying and working on these places for too long stand a risk of developing health complications if they are exposed to the radiations for too long.
dry ice is one example of this.
Answer: Find the answer in the explanation.
Explanation:
I.) A piece of wire at room temperature.
The resistance of a piece of wire at room temperature is independent of both current and the voltage because it is an Ohmic component.
II.) Filament bulb
The filament wire in the filament bulb does not obey Ohms law.
For very small currents and voltage, the graph is roughly a straight line. At higher voltages, the line starts to curve.
III.) A diode is any component that allows electric current in only one direction. The resistance of a diode depends on the potential difference across it. Therefore, it does not obey Ohms law. It is a non-Ohmic component.
