Whenever the alternating current frequency in a series RLC circuit is halved,

Physics
1 answer:
Colt1911 [192]3 years ago
8 0

Answer:

The correct option is

a. The inductive reactance is doubled and the capacitive reactance is halved

Explanation:

For a series RLC circuit, is a resonant circuit such that the impedance, Z, is minimum at the resonance frequency

Also we have that the capacitive reactance X_C, is given as follows;

X_c = \dfrac{1}{\omega \cdot C}

Where;

ω = Angular frequency = 2πf

Where;

f = The frequency in the circuit

\therefore X_c = \dfrac{1}{2 \cdot \pi \cdot f \cdot C}

The inductive reactance is also given as follows;

X_L = \omega \cdot L =  2 \cdot \pi \cdot f \cdot L

Therefore, when the circuit frequency doubles, the inductive reactance doubles and the capacitive reactance halves

The efficiency of the scissor is 200%.

<u>Explanation:</u>

Efficiency is defined as the ratio of output of any instrument or device or machine to the input supplied to it. So the greater the output the greater will be the efficiency of the device.

As here the work done by us on the system is said to be 10 J so this will be equal to the input work done on the system. And the work done by the system i.e., the scissor is 20 J, so this will be the output work.

So, the efficiency is the ratio of output to input as shown below.

Efficiency = (\frac {20} {10} ) \times 100 = 200

So, the efficiency of the scissor is 200%.

State the relation between acceleration and momentum
vredina [299]

Answer:

Acceleration is the rate of change of velocity. Momentum is the mass times the velocity. So if you multiply the mass times the acceleration, you get the rate of change of momentum
