Answer:

Explanation:
From the question we are told that
Force of power 
Velocity of power 
Generally the equation for power is mathematically represented as


Generally the dot product of F and V is mathematically given as


Answer:
10 N to the left.
Explanation:
Since the forces are acting in opposite directions, you need to calculate the difference.
20 N - 10 N = 10 N
More force is being exerted to the left. Therefore, the net force is 10 N to the left.
48 M to get the answer add the area of the triangle and rectangle under the line
R=ρ
Where, R is resistance
ρ is resistivity,
L is length and
A is cross sectional area
Given, L= 3.5m
A=5.26 x 10⁻⁶ m²
ρ=1.68×10⁻⁸ ohms m
∴ R= 
⇒ R=1.11×10⁻² ohms
