Setting up an integral of
rotation is used as a method of of calculating the volume of a 3D object formed
by a rotated area of a 2D space. Finding the volume is similar to finding the
area, but there is one additional component of rotating the area around a line
of symmetry.
<span>First the solid of revolution
should be defined. The general function
is y=f(x), on an interval [a,b].</span>
Then the curve is rotated
about a given axis to get the surface of the solid of revolution. That is the
integral of the function.
<span>It all depends of the
function f(x), which must be known in order to calculate the integral.</span>

Graph B represents the velocity of the sphere changes over time when falling with constant acceleration.
- Acceleration is the measure of how quickly a body's velocity varies with regard to time, and constant acceleration occurs when a body's velocity changes proportionately over a period of time, or at a constant rate. It measures in m/s2.
- It is claimed that a body has continual positive acceleration when it begins to move with an initial velocity of zero and gradually increases to a positive value over time.
- Constant positive acceleration is demonstrated by a ball falling freely in a vertical direction.

The amount of extra electrons present on the negative surface is
57.2 x 
.
Distance =1.6 cm
Side = 24 cm
Electric field = 18000 N/C
Calculating the capacitance in the metal plates is necessary.
Using the capacitance formula
Putting the value
C = 8.85 x 
x (24 x 
/1.6 x
C = 0.318 x 
F
<h3>Calculation of potential</h3>
V = Ed
V = 18000 x 1.6 x V
V = 288 V
<h3>Calculation of charge</h3>
Q = CV
Q = 0.318 x x 288
Q = 91.54 x C
Charge on the both the plates
Q = +91.54 x
Q = - 91.54 x
Calculation of excess electrons on the negative surface:
n = q/e
n = 91.54 x / 1.6 x 
n = 57.2 x electrons
Hence, the number of excess electrons on the negative surface is
57.2 x .
