Resistance of a wire is directly proportional to its length and inversely proportional to the square of its radius.
Thus, if the length is doubled, and the radius is halved:
R₂ = 2R₁/(1/2)²
R₂ = 8R₁
Therefore the resistance increases eight times.
...a nerve. These send signals from the body to the brain and vice versa.
Ke=1/2mv^2
Ke= 0.5*30*20^2
Ke= 6000joules
Heaviest one always have the most kinetic E. for example, Didier drogba was running then nobody can stop him cuz his heavyyyyyy
Force is equal to mass multiplied by acceleration. Hope this helps!
