Find the ratio of gears of your bicycle.
Count the number of teeth of the chain wheel and the number of teeth of the sprocket wheel.
{number of teeth of the chain wheel} : [number of teeth of Sprocket wheel)
This is called gear ratio. Write the number of times the Sprocket wheel turns for every time the chain wheel rotates.

Write the number of different sets of teeth.

A compound is formed by two elements M and N . The element N forms ccp and atoms of M occupy (1)/(3) rd of tetrahedral voids . What is the formula of the compound ? i) Find the number of tetrahedral voids as number of tetrahedral voids = 2 xx number of atoms present in the lattice . ii) Calculate the number of atoms (or ratio) of elements M and N as a chemical formula represents the number of atoms of different elements presents in a compound . iii) Derive the formula .

A spinner was spun 1000 times and the frequency of outcomes was recorded as in given table. Find (a) List the possible outcomes that you can see in the spinner (b) Compute the probability of each outcome. (c) Find the ratio of each outcome to the total number of times that the spinner spun (use the table)

A stationary wheel starts rotating about its own axis at constant angular acceleration. If the wheel completes 50 rotations in first 2 seconds, then the number of rotations made by itin next two seconds is

A wheel has a speed of 1200 rev/min and is made to slow down at a rate of 4 rads^(-2) . The number of revolutions it makes before coming to rest is
