Answer:
Voltage across 2 cm² wire = 29.5 V
Explanation:
We equation for resistance,

Where ρ is resistivity, L is length and A is area.
Here for the four wires ρ and L is same, only area is different.
So we have

Here total voltage is given as 120 V,
In series connection voltage divides in the ratio of resistances
That is


Voltage across 2 cm² wire 
Voltage across 2 cm² wire = 29.5 V
Distance is how far something moves in a specific amount of time.
C. Generally, gravity is the only force acting on a projectile (causing it to fall down towards the earth). If you took this away, it would have no forces acting on it and, according to Newton's 1st law of inertia, it would continue moving indefinitely
Answer:
35.792 N
Explanation:
d = Diameter of rod = 2.7 cm
h = Length of rod = 81.7 cm
= Density of rod = 7800 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
Volume of rod

Mass is given by

Weight is given by

The weight of the rod is 35.792 N
