Rehman is making a wheel using spokes.He wants to fix equal spokes in such a way that the angles between any pair of consecutive spokes are equal.Help him by completing the following table:
.

Calculated the angle between a pair of consecutive spokes on a wheel with 15 spokes.

How many spoeks would be needed,if the angle between a pair of consecutive4 spokes is 40^@ .?

Are the number of spokes and the angles formed between the pairs of consecutive spokes in inverse proportion?

Just as precise measurements are necessary in science, it is equally important to be able to make rough estimates of quantities using rudimentary ideas and common observations. Think of ways by which you can estimate the following : (where an estimate is difficult to obtain, try to get an upper bound on the quantity). the mass of an elephant

Consider a pair of identical pendulums, which oscillate with equal amplitude independently such that when one pendulum is at its extreme position making angle of 2^@ to the right with the vertical, the other pendulum makes and angle of 1^@ to the left of the vertical. What is the phase difference between the pendulums?
