Q5. How can you change the frame rate with the help of code, with and without using the stage property?

Q6. Why do we need to embed fonts to a dynamic text field?

Q7. How are _root and _level different?

Q8. How are _root and parent different?
Ans: "_root" is the main timeline of the currently active movie. "parent" is the container movie of the currently active movie clip.

Q9. Write a code sample to draw line between the given two points?
Ans: We use the "lineTo(x,y)" API. Here is the example code:

    var mc:Sprite = new Sprite();
    mc.x = 50;
    mc.y = 50;
    this.addChild(mc);
    mc.graphics.lineTo(100,100);

This sample code defines a movie clip at (50,50), and draws a line from this point to (100,100). Now line is the mc. We can further draw more lines to other points also.

Q10. How do you add listener to a particular display object? What are the arguments that you need to pass to the listener?
Ans: Refer to the post: http://bashwithflash.blogspot.com/2011/01/capturing-events-in-flash-as3-part-ii.html
