A circuit with an impedance of 5 ohms and a voltage of 100 volts has a current flow of 20 A.
The expression of an electronic component, circuit, or system's resistance to alternating and/or direct electric current is called impedance, indicated by the letter Z. Resistance and reactance are two distinct scalar (one-dimensional) phenomena that combine to form impedance, a vector (two-dimensional) variable.
=
(for a pure resistor where Z=R,preserving the form of the DC Ohm's law).
I = 20 A
Therefore, A circuit with an impedance of 5 ohms and a voltage of 100 volts has a current flow of 20 A.

The total mechanical energy is
Explanation:
The total mechanical energy (TME) of an object is equal to the sum of its gravitational potential energy (U) and its kinetic energy (K):
When the car is at rest 50 m above the ground, its speed is zero, therefore its kinetic energy is zero as well:
K = 0
This means that the TME is just equal to the gravitational potential energy:
where:
m is the mass of the car
is the acceleration of gravity
h is the height above the ground
For the car in the problem,
m = 575 kg
h = 50 m
Substituting,
