A dielectric material is inserted between the charged plates of a parallel-plate capacitor. Do the following quantities increase
2 answers:
Answer:
1. increase
2. remain the same
3. increases
4. decreases
5. remain the same
6. increases
7. decreases
8. remain the same
Explanation:
a. the formula for the capacitance of a capacitor relating the capacitor and the dielectric material is express as
........equation 1
also the capacitance and the charge is related as
Q=CV.......equation 2
from equation 1 as the dielectric material is introduced, the capacitance increases, the charge also increases
2. from the equation as the dielectric material is introduced, the capacitance increases, the electric potential also remain the same
3. from
........equation 1
we conclude that the capacitance increases
4. the voltage between the plates decreases
5. the charge remain the same because capacitance is constant
6. the capacitance increases
7. the electric potential decreases
8. remain the same

Answer:
1)
In this circuit (see attachment #1), we have:
- A voltage source: in this case, we choose a battery. A voltage source is a device producing an electromotive force (in a battery, this is done by means of a chemical reaction), which is responsible for "pushing" the electrons along the circuit and creating a current. The electromotive force (emf) of the battery is also called voltage, and it is indicated with the letter V.
- Four resistors: a resistor is a device which opposes to the flow of current. The property that describes by "how much" the resistor "opposes" to the flow of current is called "resistance", and it is indicated with the letter R.
- In this circuit, the 4 resistors are in series. Resistors are said to be in series when they are connected along the same branch of the circuit, so that the same current flow across each of them.
- For resistors in series, the equivalent resistance of the circuit is given by the sum of the individual resistances:
2)
In this circuit (see attachment #2), we have:
- A voltage source: as before, we have chosen a battery, providing an electromotive force to the circuit
- Three resistors wired in parallel. Resistors are said to be connected in parallel when they are connected along different branches, but with their terminals connected to the same point, so that each of them has the same potential difference across it.
- For resistors in parallel, the equivalent resistance of the circuit is calculated using the formula:
3)
In this circuit (see attachment #3), we have:
- A voltage source (again, we have choosen a battery)
- Three resistors, of which:
-- 2 of them are connected in parallel with each other
-- the 3rd one it is in series with the first two
If we call the resistances of the first 2 resistors in parallel, their equivalent resistance is:
Then, these two resistors are connected in series with resistor ; and so, the total resistance of this circuit will be:
4)
In this circuit (see attachment #4), we have:
- A voltage source (again, a battery)
- We have 6 resistors, which are arranged as follows:
-- Two branches each containing 3 resistors
-- The two branches are in parallel with each other
So, the total resistance of the two branches are:
And since the two branches are in parallel, their total resistance will be:
Kinematics : Study of motion
Fluid kinematics : study of how fluid flows and how to describe its motion.
There are two ways to describe fluid motion
one is Eulerian, where the variations are described at all fixed stations as a function of time.
the other is Lagrangian, in which one follows all fluid particles and describes the variations around each fluid particle along its trajectory.
<u>DIFFRENCE BETWEEN LAGRANGIAN AND EULERIAN:</u>
1.Both Lagrangian and Eulerian describes time variation.
2. Eulerian describes the rate of change in one point of space
Lagrangian descries rate of change of a property of material system.
