The temperature that the aluminum will have a resistivity that is three times the resistivity copper has at room temperature is 227°C.
<h3>How to calculate the temperature?</h3>
It should be noted that the temperature of resistivity is given as:
p(t) = p(20°C) (1 + (t - 20°C)
The resistivity at room temperature is illustrated as:
pCu(20°C) = 1.68 × 10^-8
pAl(20°C) = 2.65 × 10^-8
Therefore, the equation will be:
3 × 1.68 × 10^-8 = 2.65 × 10^-8(1 + 0.00435(t - 20°C)
0.902 = 0.00435(t - 20°C)
t = 20 + 207
t = 227°C
Therefore, the temperature is 227°C.

The electric potential at point b experienced by the charge cab be determined using the formulas given.
<h3>Electric potential</h3>
The electric potential of a point charge is the work done in moving the charge from infinity to certain point against the electric field.
V = Ed
V = (F/q)d
V = (Fd)/q
where;
- V is the electric potential
- F is electric force
- E is the electric field
- q is the charge
Thus, the electric potential at point b experienced by the charge cab be determined using the formulas given.

Kinetic friction, for example, generally turns energy into heat, and although we associate kinetic friction with energy loss, it really is just a way of transforming kinetic energy into thermal energy. The law of conservation of energy applies always, everywhere, in any situation. ?
This would be Newton's first law, which states that an object at rest will stay at rest and an object in motion will remain in motion unless acted on by an unbalanced force. Hope this helped.
