Speed
In an athletic meet different participants start running at the same time and cover the same distance. The person who takes the minimum time to cover the distance will be judged as the winner. Suppose Ram and Krishna take 20 minutes and 10 minutes respectively to cover a distance of 1000 m, who is ..

Ram and Krishna run in different races covering different distances. Ram takes 20 minutes to cover 1000 m and Krishna takes 10 minutes to cover 700 m. Who is faster? To find out who is faster we shall calculate the distance covered by them in one minute. Krishna covered more distance in unit..

The previous example does hold good only if we ignore the friction or resistance offered by the surface. The distance covered varies with time. For example, a rubber ball dropped from a height, on reaching the ground bounces off to a height less than the initial height and slowly the height decreas..

Relation Between Atomic Mass Unit and MeV (Mass Energy Relation)
The unit in which atomic and nuclear masses are measured is called atomic mass unit (a.m.u). 1 a.m.u is defined as 1/12 t h of the mass of an atom of 6 C 1 2 isotope. It can be shown that 1 a.m.u = 1.66 x 10 2 7 kg. According to Einstein, mass energy equivalence E = mc 2 Where m..

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 ..

Mass-energy equivalence
Albert Einstein, in the beginning of this century, showed that matter (whatever the form) was equivalent to energy. The energy associated with a mass 'm' (just because of its existence) is given by the famous formula of Einstein, E = mc 2 ------------ (1). where 'c' is the speed of ligh..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
This is very helpful and explains everything thoroughly. when asked to do problems slowly, tutors did them very thoroughly and even went extra mile to explain how and why with text - I just bow down to Turor Vista
Looking for More Help!
