Answer:
<em>The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.</em>
We know that the Pythagorean theorem applies only to right triangles, therefore the original vectors must be parallel to the legs of a right triangle.
In other words, they must be orthogonal (i.e. perpendicular to each other) in order that the Pythagorean theorem applies.
The current density of the copper wire is determined as (7.059 x 10⁸ A/m²)/L
<h3>Current density of the copper wire</h3>
The current density of the copper wire is calculated as follows;
J =1/ρ(E) = 1/ρ(V/L)
where;
- E is electric field
- V is voltage
- L is length of the wire
<h3>Current density the wire</h3>
J =1/ρ(E) = 1/ρ(V/L)
J = (1/1.7 x 10⁻⁸) x (12)/L
J = (7.059 x 10⁸ A/m²)/L

Answer: B
Explanation:
A - No, because this has nothing to do with curves
B - Yes, because it explains gravity and it it forced down by gravity
C - No, because this has nothing to do with a rocket ship an dhow much it can travel per #.
D - No, because This has nothing to do with a boat on water and it explain nothing about gravity or how fast it is.
