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.

Answer:
Mass = 18.0 kg
Explanation:
From Hooke's law,
F = ke
where: F is the force, k is the spring constant and e is the extension.
But, F = mg
So that,
mg = ke
On the Earth, let the gravitational force be 10 m/.
3.0 x 10 = k x 5.0
30 = 5k
⇒ k = ................ 1
On the Moon, the gravitational force is of that on the Earth.
m x = k x 5.0
= 5k
⇒ k = ............. 2
Equating 1 and 2, we have;
=
m =
= 18.0
m = 18.0 kg
The mass required to produce the same extension on the Moon is 18 kg.
