BB101: Adding Forces as Vectors

How to add two forces acting onto a point but in a different  direction and plane?

As we know that forces are vector, so we cannot adding or subtracting them like the scalar magnitude, therefore we have to use the triangle law or parallelogram law to determine the resultant. Please watch the video below to enhance your knowledge.(This video is a copyright of Lucid Education)

BA202 : DOES INFINITY COUNTABLE?

Dear student,

Our last class we do a lot of discussion on a set of Numbers. All numbers are infinity...such as the Positive Integer I = {1,2,3,4....} and so with the Natural number N= {0,1,2,3....}. But both Integer and Natural Number can be listed so we call it the countable infinity.

In other hand, decimal number cannot be listed......even you try to list a decimal number from 0 to 1, therefore, we call that decimal numbers are uncountable infinity. So did you get the idea? try to find another set of number which can be classify as uncountable infinity....
