If bara and barb are unit vectors and theta is the angle between them, show that frac(1)(2)[bara-barb] = sin frac(theta)(2)

The magnitudes, of the two vectors A and B are both not equal to zero but barA.barB=0Then the angle between the vectors is (in degrees).

If resultant of two vectors of equal magnitude is equal to the magnitude of either vector what is the angle between them?

Write the experimental procedure carried ouyt by Faraday, that relative motion between a bar magnet and a wiore loop produce current.

Double Bar Graph : A bar graph showing two sets of data simultaneously. It useful for the comparison of the data. What is the information given by the double bar graph?
