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.

When he bends he kinda off his feet and light but if it’s not i’m so sorry this is just my thinking.
centrifugal force is a fictitious force. What is happening is that since the earth itself is not a rigid body it will deform when under motion. Although gravity attempts to make the earth spherical, as it is rotating the earth deforms, in such away that it flattens to become an oblique spheroid. This happens as the material at the equator must have a net resultant centripetal force (not centrifugal) which causes its position of equilibrium from the center of the earth to be further away than at the poles as they do not have this force as they are not rotating around the center of mass.
because it deals with reaction
