Answer:
![2.1\times 10^{-12} c](https://tex.z-dn.net/?f=2.1%5Ctimes%2010%5E%7B-12%7D%20c)
Explanation:
We are given that
Surface area of membrane=![5.3\times 10^{-9} m^2](https://tex.z-dn.net/?f=5.3%5Ctimes%2010%5E%7B-9%7D%20m%5E2)
Thickness of membrane=![1.1\times 10^{-8} m](https://tex.z-dn.net/?f=1.1%5Ctimes%2010%5E%7B-8%7D%20m)
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
![C=\frac{k\epsilon_0 A}{d}](https://tex.z-dn.net/?f=C%3D%5Cfrac%7Bk%5Cepsilon_0%20A%7D%7Bd%7D)
Substitute the values then we get
Capacitance between parallel plate capacitor=![\frac{5.9\times 8.85\times 10^{-12}\times 5.3\times 10^{-9}}{1.1\times 10^{-8}}](https://tex.z-dn.net/?f=%5Cfrac%7B5.9%5Ctimes%208.85%5Ctimes%2010%5E%7B-12%7D%5Ctimes%205.3%5Ctimes%2010%5E%7B-9%7D%7D%7B1.1%5Ctimes%2010%5E%7B-8%7D%7D)
![C=0.25\times 10^{-12}F](https://tex.z-dn.net/?f=C%3D0.25%5Ctimes%2010%5E%7B-12%7DF)
V=![85.9 mV=85.9\times 10^{-3}](https://tex.z-dn.net/?f=85.9%20mV%3D85.9%5Ctimes%2010%5E%7B-3%7D)
![Q=CV](https://tex.z-dn.net/?f=Q%3DCV)
![Q=0.25\times 10^{-12}\times 85.9\times 10^{3}=2.1\times 10^{-12} c](https://tex.z-dn.net/?f=Q%3D0.25%5Ctimes%2010%5E%7B-12%7D%5Ctimes%2085.9%5Ctimes%2010%5E%7B3%7D%3D2.1%5Ctimes%2010%5E%7B-12%7D%20c)
Hence, the charge resides on the outer surface=![2.1\times 10^{-12} c](https://tex.z-dn.net/?f=2.1%5Ctimes%2010%5E%7B-12%7D%20c)
Disagree.
Fluoresce objects will only glow when put under actual Ultraviolet light. This is due to the molecules becoming excited by the ultraviolet radiation.
Microwaves give micro-waves that are present in another spectrum of wave length and will not be able to fluoresce the molecules. If it’s not “ultra violet “.... it’s not going to glow.
<span>The atom becomes positively charged.
When you add electrons to a neutral atom, it is no longer a neutral atom, it has a negative change and is an anion. When you take away electrons from a neutral atom, it is no longer a neutral atom- it becomes a positive atom, and is a cation.</span>
Answer:
EXplained
Explanation:
from conservation of energy
change in potential energy = gain in kinetic energy
so as all he balls are throws from the same height thus the change in potential energy is the same for all the balls thus the gain in kinetic energy is the same for all the balls and as they have the same initial velocity thus the final velocity is the same for all the balls.
