At resonance, what is impedance of a series RLC circuit? less than R It depends on many other considerations, such as the values

of L and C. larger than R equal to R Which of the following does the quality factor of the circuit depend on? (Select all that apply.)

3 0

Answer:

at resonance impedence is equal to resistance and quality factor is dependent on R L AND C all

Explanation:

we know that for series RLC circuit impedance is given by

Z=\sqrt{R^2+\left ( X_L-X_C \}right )^2

but we know that at resonance X_L=X_C  

putting  X_L=X_C in impedance formula , impedance will become

Z=R so at resonance impedance of series RLC is equal to resistance only

now quality factor of series resonance is given by

Q=\frac{\omega L}{R}=\frac{1}{\omega CR}=\frac{1}{R}\sqrt{\frac{L}{C}}  so from given expression it is clear that quality factor depends on R L and C

Which data set has the smallest standard deviation?
777dan777 [17]
The answer would be B.
<span>
Standard deviation basically measures how spread out the values are. Without solving, you can easily tell which one among your choices have a smaller deviation. The closer the values are to each other the smaller the standard deviation. The values of choice B are the closest together, so you can assume that they have the smallest standard deviation. </span>

True or false: Balanced forces can change an object's direction?
slava [35]

The statement is false.  Balanced forces can NOT change the speed OR direction of an object's motion.  (See Newton's #1 law of motion.)

In a race, you run 3000 meters east in 21 minutes. What is your velocity in km/min?
STALIN [3.7K]

velocity = distance / time      v= d/t          firstly you change 3000 m into km     distance  D = 3000/1000  = 3 km             secondly   time t = 21 min      using velocity formula v = d/t       = 3 km/21min       =0.142km/min
