The resistance of the wire is dependent on temperature, diameter and nature of the material.
<h3>What is resistance?</h3>
The term resistance refers to the opposition offered to the flow of current in a circuit. The resistance is obtained form Ohm's law which states that;
V = IR
Where;
V = voltage
I = current
R = resistance
Hence, the resistance is dependent on;
- temperature
- diameter
- material

Answer:
A decrease in temperature decreases
the number of collisions between molecules
. The reaction rate will decrease
Explanation:
The potential energy of the ball is 8 J.
<h3>What is mechanical energy?</h3>
Mechanical energy is given as the energy possessed by an object to do work. It is given as the sum of the kinetic energy and potential energy.
Mechanical energy = Kinetic energy + Potential energy
The given ball has:
- Mechanical energy = 25 J
- Kinetic energy = 17 J
The potential energy is given as;
25 J = 17 J + Potential energy
Potential energy = 25 J - 17 J
Potential energy = 8 J
The potential energy of the ball is 8 J.

If anything you would use a protractor but that’s not a answer.... so I would pick whatever relates to a protractor
