All forces must add up to zero. See pictures below.
Answer:
1.2 m/s
0.31 m
0.15 m
Explanation:
Time period is

Frequency is

Velocity is given by

The waves are traveling at 1.2 m/s
Amplitude is given by

Amplitude is 0.31 m
If d = 0.3 m

The amplitude would be 0.15 m. The speed would remain the same.
Answer:

Explanation:
We are given that
Surface area of membrane=
Thickness of membrane=
Assume that membrane behave like a parallel plate capacitor.
Dielectric constant=5.9
Potential difference between surfaces=85.9 mV
We have to find the charge resides on the outer surface of membrane.
Capacitance between parallel plate capacitor is given by

Substitute the values then we get
Capacitance between parallel plate capacitor=

V=


Hence, the charge resides on the outer surface=
