The molecules give off heat.
If we increase the length of the resistor, resistance will also increase and vice-versa.
It is given that in a wire simulation, we have to adjust only the length of the resistor.
It required to find the effect on resistor when adjust only the length of the resistor.
<h2>What happens to resistor when adjust only the length of the resistor?</h2>
As we know that the length is directly proportional to the resistance of the wire that means is we increase the size or length of the wire then it also increase the resistance present in the wire. On the other hand if we decrease the length of the wire, it will decrease the resistance. This can be represented as:
Resistance = resistivity × length/area
This is also because there is more collision of the flowing electrons in the wire to the metal ions present there.
Thus if we increase the length of the resistor, resistance will also increase and vice-versa.

Protons
electrons are negatively charged
neutrons are neutral
Answer:
20x120=2400m equivalent to 2km
15x120 =1800 m = 1.8km
2km +1.8 km = 3.8 km
