As we know, exam time is most difficult for the student whether they study correctly or not. This time is also required mental preparation which comes through more than ten times revision and then memories...
Practical calculations need to be done using log tables. In order to do so, here are some important formulae. log(mn) = n log(m) log(m×n) = log(m) + log(n) log(m/n) = log(m) - log(n) The log...
If a particle moves in such a way that its distance from a fixed point remains constant to the path will be circular and its motion is called circular motion. If we whirl a stone tied with a string at...
