Check out us at:http://physics.tutorvista.com/motion/vector.html Scalars and Vectors Vectors: A vector is a leaning quantity; it has magnitude and the direction. Velocity, force and displacement these are the examples for vectors. Vectors are represented using the arrow above the letters like Vec (a). Normally a vector needs two main things which are magnitude and direction. Scalars: Sca...

The degree of P (x) (polynomial) is less than or equal to one. Then let us consider 'a' is real number. If P(x) is divisible by the binomial (x-a) then the remainder is P (a).

Follow us at: https://plus.google.com/+tutorvista A chemical equation describes what happens in a chemical reaction. The equation identifies the reactants (starting materials) and products (resulting substance), the formulas of the participants, the phases of the participants (solid, liquid, gas), and the amount of each substance. Balancing a chemical equation refers to establishing the mathemat...
Follow us at: https://plus.google.com/+tutorvista The number of protons in the nucleus of an atom determines an element's atomic number. In other words, each element has a unique number that identifies how many protons are in one atom of that element. For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1. All carbon atoms, and only carbon ato...
