Answer:
486.76 Hz ; 1460.29 Hz
Explanation:
Given that :
Length of vocal tract = 17cm
Velocity of sound in air = 331 m/s
The first and second formants of the voice ;
First formants :
F1 = V / 4L
V in m/s ; L in m
F1 = (331 m/s) / (4 * 17/100 m)
F1 = (331 m/s) / 0.68 m)
F1 = 486.76470 Hz
F1 = 486.76 Hz
Second Formants :
F2 = 3V / 4L
V in m/s ; L in m
F2 = (3 * 331 m/s) / (4 * 17/100 m)
F2 = (3 * 331 m/s) / 0.68 m)
F2 = 993 m/s / 0.68 m
F2 = 1460.2941 Hz
F2 = 1460.29 Hz
Answer:
-35 mV and +56 mV
Explanation:
The membrane potential is the energy that is needed to drive membrane changes across the phospholipid bi-layer membrane.
Ions can move in and out of the cell through protein channels. The movement of the ions is as a result of concentration that affect the operation of ion gates.
The reverse potential is given by the Nernst equation:

where, R = gas constant
T = temperature (Kelvin)
z = ion charge
F = Faraday's charge
The potential is calculated and the result is -35 mV and +56 mV respectively.

These are mutually exclusive - even though they just bought the company, the assets and equity are still going to decrease, at least for the time being.
