Code generation can be speeded uo a bit, using macros and proper coding scheme.

Surprisingly, we are not always aware of things available to us. MS Word, for example, has the capability to reproduce a chunk of text with a stroke of key combination. This appears a great facility, particularly for speeding up writing any mark up codes, including MathML. This facility, though available all the time, is hardly ever used in normal text editing session with MS Word.

Using the facility to create macros in MS Word is simple. Matter of fact, this is one of the reasons for recommending an advanced text editing software like MS Word as against bare editors like Notepad for writing plane text MathML code lines.

We need to create macros for writing a set of code lines for the basic coding forms for most of the frequently used element and assign the same to a keyboard combination like ALT a, ALT b etc. Subsequently, when we need to write the code lines for MathML element in the basic form, we shall require to simply use the key combination and the code lines will be reproduced. It is warned that we must provide sufficient space between existing code or text lines so that the reproduced text by macros do not mix up. This techniques, involving macros, has the advantage that once a correct format is recorded, it is less likely that there would be any syntax error.

Creating macros for mathml basic forms of elements

In this section, the exact steps to create a macro with few code lines involving “mfrac” element are given. Before we proceed, we must realize that choosing a particular size and font to write the codes in macros is extremely important. The renderer accepts MathML in mono font for the code lines. What it means that we should encode our markups in one font only. A mix of many fonts results from “copy” and “paste” operations from different sources. We must avoid font mixing so that the renderer does not report error, while displaying the content.

Now, follow the steps to create a macro for the basic form of “mfrac” element :

Step 1: Open MS Word. Create a new document. Save the document as “test.doc”, ensuring that “save as type” is a word document. Note that we can not recordand store macros in plane format, which is used for encoding MathML.

Step 2: Select “Courier New” from the font drop down as shown here :

Font selection

Select font size 12 from the adjacent drop down.

Step 3 : Write code lines for the basic form of the “mfrac” element as shown here :

<m:mfrac> <m:mi> x </m:mi> <m:mi> y </m:mi> </m:mfrac>

Step 4 : Select “Tools” from the top tool bar of MS Word and choose “Record New Macro” as shown below :

Recording macros

Step 5 : “Record macro” dialog box appears. In the “Macro name” give the name of macro, say “mfrac”. In the “Store macro in” select the name of document “test document” or the name of the document in which you are recording macro.

Setting macros

Step 6 : Press “keyboard” button. The “Customize Keyboard” dialog box appears. Put the cursor in the “Press new shortcut key” box (if not placed automatically). Press “Alt and f” to record the desired key combination to run the macro for “mfrac” code lines. Note that “Alt + F” text with capital “F” is automatically placed inside the box. In the “unassigned” box, select “test”.

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.

Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
