Momentum describes an object in motion and is determined by the product of two variables: mass and velocity. Mass -- the weight of an object -- is usually measured in kilograms or grams for momentum problems. Velocity is the measure of distance traveled over time and is normally reported in meters per second. Examining the possible changes in these two variables identifies the different effects momentum can have on an object in motion.

We think of the response of the circuit as the ratio of the maximum current to the maximum voltage provided. Explain why the rat

nexus9112 [7]

Answer:

Z = R, i = V/Z, w = √1 / LC

Explanation:

In an RLC circuit the impedance of the circuit is

Z = √[R² + ( $X_{L} - X_{C}$ )²

Where

$X_{L}$ = wL

X_{L} = 1 / wC

They are the reactances of the inductor and the capacitor, in this case the current advances to the voltage in the first and is delayed from the voltage in the second, so when the two values give the same reactance the current goes in phase with the voltage and the impedance is minimal

Z = R

V= i Z

i = V/Z

Therefore the current is maximum, this occurs when

w = √1 / LC

Saying that this is the resonant frequency

In comparing the Ptolemaic system to the Copernican system, neither is entirely correct since Ptolemy said the earth was at the center and Copernicus said <span>the planets had circular orbits. This is correct</span>
