Answer:

0.00479 volts

Explanation:

From Faraday's law of electromagnetic induction, the induced emf equals the change in magnitude flux (magnetic field strength multiplied by the area = BA) divided by the time change

Therefore we have the equation

EMF = BA÷t

Since area A = 2πr

EMF = Bπr²÷t

B = 5.5×10^(-5)

Velocity = 100km/h = 27.7778m/s

r = 1m, t = r÷V = 0.036

EMF = Bπr²÷t = (5.5×10^(-5) x π x (1)²)÷0.036 = 0.00479 Volts

What does it mean when the orbital eccentricity of a planet is close to 1?
ankoles [38]

We have that Zero signifies a perfect circle shape and 1 shows it maximum out of order shape.

From the question we are told

What does it mean when the orbital eccentricity of a planet is close to 1

Generally

Eccentricity

This in its simplest definition means to be eccentric which means to be a bit out of order or for the given subject at hand means to be a bit out of shape

Naturally the Eccentricity that an object possess is defined by two number 0(zero) to 1(one)

Where

Zero signifies a perfect circle shape and 1 shows it maximum out of order shape

How is the q of an rlc parallel resonant circuit calculated?
notka56 [123]

Answer:

It is calculated by dividing Resistance, R, by Inductive reactance, XL.

Explanation:

Q is called the Q factor of a resonance circuit. In a parallel resonance circuit, it is calculated by finding the ratio of the power stored in the circuit to the power distributed in the circuit. It is a way of measuring the quality of a circuit or how effective the circuit is.

Q factor is the inverse in the resonance series circuit.

Q factor of a resonance parallel circuit,

<h3>Q = R/XL</h3>

R = Resistance

XL = Inductive reactance
