Write a script to plot function
$y=\frac{\sin x}{x}$ for
$\frac{\pi}{100}\le x\le 10\pi $ using increments of
$\frac{\pi}{100}$ . Publish your m-file to html.
The m-file content:
% This script plots a graph of Graph of y=sin(x)/x
clc % Clear screenx = pi/100:pi/100:10*pi; % Create a row vector
y = sin(x)./x; % Calculate y as function of xplot(x,y),title('Graph of y=sin(x)/x'),xlabel('x'),ylabel('y'),grid The html output:
A gas is expanded in an engine cylinder, following the law PV1.3=c. The initial pressure is 2550 kPa and the final pressure is 210 kPa. If the volume at the end of expansion is 0.75 m3, write a script to compute the work done by the gas and publish your solution to an html file.
This is the same problem as this Problem you have solved before.
The m-file content:
clc
disp('A gas is expanded in an engine cylinder, following the law PV^1.3=c')disp('The initial pressure is 2550 kPa and the final pressure is 210 kPa.')
disp('If the volume at the end of expansion is 0.75 m3,')disp('Compute the work done by the gas.')
disp(' ') % Display blank linen=1.3;
P_i=2550; % Initial pressureP_f=210; % Final pressure
V_f=.75; % Final volumeV_i=(P_f*(V_f^n)/P_i)^(1/n); % Initial volume
c=P_f*V_f^n;v=V_i:.001:V_f; % Creating a row vector for volume, v
p=c./(v.^n); % Computing pressure for volumeWorkDone=trapz(v,p) % Integrating p*dv The html output:
A force F acting on a body at a distance s from a fixed point is given by
F=3s+\frac{1}{s^{2}} . Write a script to compute the work done when the body moves from the position where s=1 to that where s=10 and and publish your solution to an html file. Include a table of contents in the output file.
This is the same problem as this Problem you have solved before.
The m-file content:
%% Work done
% This script computes the work done on an objectclc
disp('A force F acting on a body at a distance s from a fixed point is given by')disp('F=3*s+(1/(s^2)) where s is the distance in meters')
disp('Compute the total work done in moving')disp('From the position where s=1 to that where s=10.')
disp(' ') % Display blank line%% Create a row vector for distance, s

Questions & Answers
Is there any normative that regulates the use of silver nanoparticles?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Harper
Do you know which machine is used to that process?
