Answer:
A. It is made of tissues that can conduct electricity, a required function in a system.
Explanation:
The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.
Answer:
Cost to leave this circuit connected for 24 hours is $ 3.12.
Explanation:
We know that,

f = frequency (60 Hz)
c= capacitor (10 µF =
)

Substitute the given values



Given that, R = 200 Ω





X = 332.31 Ω


Current (I) = 0.361 amps
“Real power” is only consumed in the resistor,



In one hour 26 watt hours are used.
Energy used in 54 hours = 26 × 24 = 624 watt hours
E = 0.624 kilowatt hours
Cost = (5)(0.624) = 3.12
Answer:
The funda mental frequency of the original tube is 182Hz.
Explanation:
See the attachment for the calculation steps.
In order to calculate the fundamental frequency of the original closed tube we need to find the length of the tube which is equal to the sum of the lengths of the two new tubes.
For closed tubes
f = nv/4L (n = 1, 3, 5,...n)
f = nv/2L (n = 1, 2, 3,...n)
The details of calculation can be found below in the attachment.
Answer:
e. 400 Hz
Explanation:
In closed organ pipe, only odd harmonics of fundamental note is possible .
The fundamental frequency is 200 Hz . Then other overtones will be having following frequencies .
200 x 3 , 200 x 5 , 200 x 7 , 200 x 9 etc
600 Hz , 1000 Hz , 1400 Hz , 1800 Hz .
Frequency not possible is 400 Hz .
