Laws of Magnetism
To find out about laws of magnetism you can perform the following simple experiment. Suspend a bar magnet as shown in figure, so that it can freely rotate. Allow it to come to rest. You will notice that it remains in north-south direction. Now bring N pole of second bar magnet near N pole..

The First Law of Thermodynamics - We have seen that heat is just a form of energy. A system can be given energy either by supplying heat to it (by placing it in contact with a hotter object) or by doing mechanical work on it. Consider an ideal gas in a cylindrical container, fit..

>A metal contains a large number of free electrons. They move at random within the metal with different velocities. But at ordinary temperatures, they cannot leave the surface due to attractive forces between the electrons and the positive ions. If the metal is heated, the kinetic energy ..
Expression for Work
Expression for Work - Let us take a ball that can slide along a frictionless wire, stretched along the horizontal X-axis. A constant force directed at an angle. f to the wire, accelerates the bead along the wire. According to Newton's second law F x = ma x ______(1) As the ball ..

Tutors are AMAZING, and They helped me understand every single part of the problem and because of the way they explained everything, i had no questions to ask. It was a learning experience to remember. :)
My daughter is in 9th grade and I was having a hard time helping her. I am finding TutorVista very helpful. I don't want my daughter to think she knows more than her Mom :-) Thank you all - Megan
Very good patient and encouraing than my school teacher. I would love to study with tutor vista rather than going to school.
It was fun! It showed me a easier way to do multiplication with bigger numbers,Thank you all - Christian
