Answer:
The potential energy is
Explanation:
From the question we are told that
The inner radius is
The outer radius is
The common length is
The potential difference is
Generally the capacitance of the cylindrical capacitor is mathematically represented as
Where is the permitivity of free space with the values
and k is the dielectric constant of the dielectric material here the dielectric material is free space so k = 1
Substituting values
The potential energy stored is mathematically represented as
substituting values
Answer:
Explanation:
The rotation rate of the man is:
The resultant rotation rate of the system is computed from the Principle of Angular Momentum Conservation:
The final angular speed is:
First calculate the the force per kilogram(0.25 / 20 or 80N) so 80m/s^2
Answer:
the easy way to describe this is to use a light as an example.
Explanation:
Voltage is pretty much the loop used to help use a lightbulb to emit light. Without voltage, we would be unable to use lightbulbs. This applies to much more than a lightbulb, but it's the easiest way to describe how voltage works.
B, because the antacid will dissolve and become something new (something new is created) in the persons' stomach.
