applied dimensional analysis and modeling

It is often necessary to convert one set of units to another. This can be done in a systematic way by the method called dimensional analysis or the conversion factor method. Conversion factor is equal to the ratio of the magnitudes of the same quantity in the two units. To obta..

Limitations of Dimensional Analysis - Dimensional analysis has no information on dimensionless constants. If a quantity is dependent on trigonometric or exponential functions, this method cannot be used. In some cases, it is difficult to guess the factors whi..

Head-on Elastic Collision [One Dimensional Elastic Collision] - It is that elastic collision in which the colliding bodies move along the same straight line before and after the collision. Consider two bodies A and B of masses m 1 and m 2 respectively, moving along the same straight line,..

Victor observed that as the speed of the bus increases, it moves more distance before it stops after breaks are applied. The table shows the data for different speed x of the bus and the distance it moves before stopping. Choose the model and its equation which best fits the sit..

A father is 28 years older than his son. In 5 years, his age will be twice the age of his son. Choose a mathematical model to find their ages. => By using geometric or coordinate techniques or By using a linear equation or By applying a formula or None of the above..

Choose an appropriate mathematical model for the problem. The perimeter of a rectangular field is 280 m. If the length of the field is increased by 3 m and breadth decreased by 2 m, then the area is decreased by 56 sq.m. Find the length and breadth of the field. => Applying a fo..

Considering the three dimensional model of ethane, the single carbon atom and the three hydrogen atoms at the back are exactly covered by the those at the front. The atoms at the back are not visible. Hence the conformation is known as eclipsed conformatio..
