I believe that some are and some aren’t… sorry I’m not to well on this.
A warm copper wire will have more conductivity
yes because your mass doesn't change but your weight can
ex- if you travel to Saturn your weight would change but your mass would stay the same
The answer is 0.981 J
E = m · g · h<span>
E - energy
m - mass
g - gravitational acceleration
h - height
We know:
E = ?
m = 0.10 kg
g = 9.81 m/s</span>²
h = 1 m
E = 0.10 kg * 9.81 m/s² * 1 m = 0.981 J
