Answer:
impedance Z = 416.66 ohm
voltage across inducance V = 346.99 V
power factor = 0.720
Explanation:
given data
resistor R = 300
voltage amplitude = 500 V
resistor = 216 W
to find out
impedance and amplitude of the voltage and power factor
solution
we apply here average power formula that is
average power = I²×R ............1
I = 
so
average power = ()²×R
Vrms = 
× Vmax
Z = V × 
Z = 500 × 
impedance Z = 416.66 ohm
and
we know voltage across inductor is here express as
V = I × X .............2
so here X will be by inductance
Z² = R² + (X)²
(X)² = 416.66² - 300²
X = 289.15 ohm
and I = 
I = 
I = 1.20 A
so from equation 2
V = 1.20 × 289.15
voltage across inducance V = 346.99 V
and
average power = Vmax × Imax × cos∅
tan∅ = 
tan∅ = 43.95°
so power factor is
power factor = cos43.95°
power factor = 0.720
Answer:
You never gave a paper I want to see the sheet pls then maybe I will see and help you did not explain it really well
Answer:
The type and length of a lunar eclipse depend on the Moon's proximity to either node of its orbit. ... A total lunar eclipse can last up to nearly 2 hours, while a total solar eclipse lasts only up to a few minutes at any given place, due to the smaller size of the Moon's shadow.

<h2>Hello!</h2>
The answer is: B. Kinetic energy
<h2>
Why?</h2>
Since the ball is falling, speed increases because the gravity acceleration is acting. When speed increases, the kinetic energy increases too, so the ball is gaining kinetic energy.
The gravity acceleration is equal to 
, it means that when falling, the ball will increase it's speed 9.81m every second.
We can calculate the kinetic energy by using the following formula:
