On Monday while Johnny was getting ready for school, he was in the bathroom holding his comb when he got an itch on his head. Jo

hnny used the comb to rub his itch away and when he did his hair was a mess. He turned on the faucet so there was a small stream of water flowing and as he brought the comb near the water to dampen it, he noticed that the water was pulling towards the comb. Thinking he was seeing things, he pulled the comb back and the water was flowing straight down. He again moved the comb near the stream of water and the water again was pulling towards the comb. He repeated this process many times and the water continued to move towards the comb when the comb was near the water.
What do you think is happening to the stream of water flowing from the faucet?
Support you claim in Question 1, by explaining why you think it is happening.
Formulate your hypothesis for the problem.

A parallel RLC resonant circuit has a resistance of 200 Ω. If it is known that the bandwidth is 80 rad/s and the lower half-powe
d1i1m1o1n [39]

Answer:

L= 3.6mH

C =9.9 microfarad

Explanation:

Resonant frequency fr

fr = fl + 1/2 BW

fr = 800+ 1/2×80

=800+40

=840 rad/s

Bandwidth (BW)

BW = fr/Q

Q = quality factor

Q= fr/ BW

Q = 840/80

Q= 10.5

Quality factor = R/Xl

Xl = inductive reactance

Xl = R/Q

Xl = 200/10.5

Xl = 19.05 ohms

Xl =2πfL

L= Inductance

L = Xl /2πf

L =19.05/5278.56

L= 3.6mH

Capacitor C

1= fr^2 × 4π^2LC

C = 1/fr^24π^2L

C = 1/100307.5

C= 9.9microfarad
