The gravitational force may grow weaker if separation occurs with the distance.
hope i helped :)
You need to convert minutes to hours so
Answer:
a) E = V/L x^
b) R = ρL/A = ρL/π(d/2)^2 = 4ρL/πd^2
c) I = V/R x^ = V/(4ρL/πd^2) x^ = πd^2*V/4ρL x^
d) J = I/A = [πd^2*V/4ρL x^]/π(d/2)^2 = V/ρL x^
e) ρJ = ρ(V/ρL x^) = V/L x^ = E
