To solve this problem we will apply the concepts related to load balancing. We will begin by defining what charges are acting inside and which charges are placed outside.
PART A)
The charge of the conducting shell is distributed only on its external surface. The point charge induces a negative charge on the inner surface of the conducting shell:
. This is the total charge on the inner surface of the conducting shell.
PART B)
The positive charge (of the same value) on the external surface of the conducting shell is:
![Q_{ext}=+Q_1=1.9*10^{-6} C](https://tex.z-dn.net/?f=Q_%7Bext%7D%3D%2BQ_1%3D1.9%2A10%5E%7B-6%7D%20C)
The driver's net load is distributed through its outer surface. When inducing the new load, the total external load will be given by,
![Q_{ext, Total}=Q_2+Q_{ext}](https://tex.z-dn.net/?f=Q_%7Bext%2C%20Total%7D%3DQ_2%2BQ_%7Bext%7D)
![Q_{ext, Total}=1.9+3.8](https://tex.z-dn.net/?f=Q_%7Bext%2C%20Total%7D%3D1.9%2B3.8)
![Q_{ext, Total}=5.7 \mu C](https://tex.z-dn.net/?f=Q_%7Bext%2C%20Total%7D%3D5.7%20%5Cmu%20C)
Answer:
See explanation
Explanation:
The degradation of the drug is a first order process;
Hence;
ln[A] = ln[A]o - kt
Where;
ln[A] = final concentration of the drug
ln[A]o= initial concentration of the drug = 5 gm/100
k= degradation constant = 0.05 day-1
t= time taken
When [A] =[ A]o - 0.5[A]o = 0.5[A]o
ln2.5 = ln5 - 0.05t
ln2.5- ln5 = - 0.05t
t= ln2.5- ln5/-0.05
t= 0.9162 - 1.6094/-0.05
t= 14 days
b) when [A] = [A]o - 0.9[A]o = 0.1[A]o
ln0.5 = ln5 -0.05t
t= ln0.5 - ln5/0.05
t= -0.693 - 1.6094/-0.05
t= 46 days
vf ^2 = kx^2/m = 56(0.75)^2 / 2.5 = 12.6
Therefore, v= 3.5 m/s.
Answer:
Kinetic Energy
Explanation:
Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. ... Kinetic energy can be transferred between objects and transformed into other kinds of energy. For example, a flying squirrel might collide with a stationary chipmunk.
Your answer would be true. Because if we didn't have those pieces of evidence, we wouldn't know about a lot of the ancient civilizations that we know today without that. Small pieces of evidence like that can help us to determine how they lived, or what they used to do, or even what they ate.
