Answer:

1.68N

Explanation:

W=F*d

KE=1/2*M*V^2

M=32kg

V= 5.1m/s

D=50m

0.5(32)(5.1^2)= 416 J

Initial energy=500 J

final energy= 416 J

lost energy= 500-416

heat lost to friction=84 J

84=F*50

84/50=F*50/50

F=1.68N

What type of relationship exists between the length of a wire and the resistance, if all other factors remain the same?
jek_recluse [69]
Resistance of the wire can be calculated using the following rule:
R = (ρ*L) / A 
where:
R is the resistance
ρ is the resistivity of the material of the wire
L is the length of the wire
A is the area of the wire

From the above relation, we can deduce that:
The resistance of the wire is directly proportional to its length assuming all other factors are constant
