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.

Answer:
Vf = 62.61 m/s
Explanation:
Since, the truck completely stops t highest point. Therefore, from conservation of energy principle:
Kinetic Energy Lost by Truck = Potential Energy Gained by Truck
(0.5)(m)(Vf² - Vi²) = mgh
(0.5)(Vf² - Vi²) = gh
where,
Vf = final velocity = 0 m/s (since, truck finally stops)
Vi = initial velocity = ?
g = acceleration due to gravity = - 9.8 m/s² (negative sign due to upward motion)
h = Height of Ramp = (Length)(Sin θ) = (400 m)(Sin 30°) = 200 m
Therefore,
(0.5)(0² m/s - Vf²) = (-9.8 m/s²)(200 m)
Vf² = (1960 m²/s²)/(0.5)
Vf = √(3920 m²/s²)
<u>Vf = 62.61 m/s</u>
