Newlands' Law
Newlands' Law of Octaves - John Alexander Reina Newland was a chemist as well as a lover of music. Newland arranged many of the known elements in the increasing order of their atomic masses. He started with the element having the lowest atomic mass (hydrogen) and ended at thorium which wa..

But, (acceleration) Hence, Therefore, F = Kma, where K is the constant of proportionality. It we choose the unit of force in such a way that it produces unit acceleration on unit mass, then 1 = K x 1 x 1 Therefore, K = 1 Therefore, F = ma Like velocity and acceleration, force is also a ve..

Expression for Acceleration due to Gravity
Expression for Acceleration due to Gravity - Consider an object of mass m lying on or near the surface of the Earth. Let M e be the mass of the Earth and R e be its radius i.e., R e is the distance between the object and the centre of the Earth. According to Newton's law of gravitation, t..

Formation of Images by Spherical Mirrors
Case I Concave Mirror - When an object is placed in front of a concave mirror, light rays from the object fall on the mirror and get reflected. The reflected rays produce an image at a point where they intersect or appear to intersect. Formation of an image by mirrors is usually shown by const..

Variation of Mass with Velocity - According to Newton's second law of motion, F = ma If a constant force 'F' is applied to a body for a very long interval of time, the velocity of the body will go on increasing due to the acceleration produced in the body. This velocity may beco..

Really liked thier styling of tutoring. Very helpful. they went step by step and had me work out the answer- Adad
i really understood it and this teachers left me amazed and opened my eyes to the real world of math! Thanks a lot ,i mean it - Alina
Better than great. That was the best 45 minutes i have spent on here. We got a lot done and i have a better understanding of the material. Thanks
It is a really good tutoring. The tutors are thoughtful, helpful, active to help students. A lot of ideas they have. Encouraging students too. -Riley
