How To: Make clouds inside a bottle

Using a huge jar and with water colored with die in it you can make clouds. To do this set up the apparatus as shown in the video. Now open up the top valve and blow air into the jar. Now this causes the air inside to be compressed as we are pushing more air into the confined jar. This creates a high pressure inside the ball. To understand how clouds are formed you need to know two concepts. The first concept is that as pressurized gas expands it cools. The second thing is that warm gases can...

How To: Understand and find x and y intercepts

In this tutorial the author explains about the concept of X and Y intercepts in coordinate geometry. She uses a graph consisting of a line to explain the concept. She tells that Y intercept of a line is nothing but the value of Y coordinate where the line crosses the Y axis. Similarly she tells that X intercept is the x coordinate of the point where the line crosses the x axis. She demonstrates this example using a graph tool. In this video the tutor shows how to find the X intercept and Y in...

How To: Understand the Scale Line Width setting in Xara Xtreme

In this tutorial the author shows how to work with dimensions in the Xara Xtreme tool. This is basically a complex concept. Now open the tool, go to window and open dimensions. Make a square. You can see the details of the square on the tool bar which shows the width height and X,Y dimensions of the image. Here the image is straight forward. Now you can add the borders to the square and see the changes in the dimensions of it. This video shows the different changes that are taken place and al...

How To: Find the standard error of the mean

In this video the tutor explains about the standard error of the mean. He starts explaining by drawing the diagram of a distribution and now he takes ten samples from the distribution and starts plotting them. He says that in theory if we do it infinite times then we can obtain the sampling distribution of the sampling mean. For the example he takes the number of samples as 10. Now depending on these values of n we can get different sampling distributions. Now he intends to find the mean of t...

How To: Calculate circular velocity & acceleration

In this video the tutors explain about the concepts of Circular Velocity and Acceleration. She explains the concepts using a real world small experiments. She shows that the equation to calculate circular velocity is v = (2 * Pi * r) / T, where r is the radius of the circle the object moves in, and T being its time period. Now she takes the values from the experiment and calculates the velocity of the other tutor who is the object that runs around in the circle for the experiment. She even co...

How To: Solve the circumference of a circle using a cookie

In this video the instructor shows you the diameter, radius and also how to find the circumference of a circle using a cookie as an example. When you draw a line against the cookie passing through its center and touching its boundaries, it is a diameter of the circle. Radius of a circle is half the diameter of the circle. The length of the circle along the border of the circle is called circumference of the circle. The formula to compute the circumference of a circle is 2 * Pi * r, where r is...

How To: Draw a two point perspective concept

Miandza teaches you how to draw a two point perspective concept. You start with a horizontal line. Draw a vertical line in the middle and starting from that, create a rhombus. Add more vertical lines at equal distance from one another. Also create a smaller rhombus in the middle and add parallel lines to the diagonal ones. Start creating boxes when the lines intersect and use a darker color to make them visible. Continue to add parallel boxes in all directions, using the lines as help. In the...
