Answer:
Hello i hope this helps you! Potential and Kinetic EnergyHold the car at the top of the ramp, and release to demonstrate the two main kinds of energy. Potential energy is placed into the car when it's lifted from the floor, and that energy is released as the car rolls down the ramp.
Explanation:

The magnetic flux through an area A is given by
where
B is the magnitude of the magnetic field
A is the area
is the angle between the direction of B and the perpendicular to the surface A.
In our problem, the area lies in the x-y plane, while B is in the z direction, this means that B and the perpendicular to A are parallel, so
and
, so we can rewrite the formula as
We can calculate the area starting from the radius:
And then using the intensity of the magnetic field given by the problem,
, we find the magnetic flux:
Answer:
length of rope is 13.04 feet
Explanation:
Given data
high = 7 feet
from the bottom = 11 feet
to find out
length of rope
solution
we use here Pythagorean Theorem
we know length of rope is here hypotenuse
so h² = 7² + 11²
so h =
h =
h = 13.038 ft
so length of rope is 13.04 feet
