General Considerations
Any tall or massive objects will obstruct space waves, since they travel close to the ground. Consequently, shadow zones and diffraction will result. This is the reason for the need in some areas for antennas higher than would be indicated by Equation (1). On the other hand, some areas receive such..
General Characteristics of Natural Radioactivity
It is a nuclear phenomenon. It is due to the instability of the nucleus. It is a spontaneous, continuous and irreversible process. It is independent of external factors such as pressure, temperature, state of substance, electrical field, magnetic field, catalyst etc. A radioactive ele..

General properties of non-contact forces
Forces at a distance Are equal and opposite. Depend upon the distance between the two objects. Depend upon the medium between the two objects for electrical and magnetic forces but not gravitational forces. Forces are described in different names. Some forces are shown in the following d..

If the resistors are connected in parallel, the reciprocal of the equivalent resistance is equal to the sum of the reciprocals of all the individual resistances. This result can be generalized for any n number of resistors. From the above derivations we find that if we want to increase th..

Laws of Refraction
Refraction of Light In general, if a ray of light is passing from medium 1 to medium 2, then If the medium 1 is air or vacuum, the refractive index of medium 2 is referred to as the absolute refractive index. The refractive index of a medium depends on the following factors: the nature of..

X-Ray Emission
V. When this electron hits the target, it loses its kinetic energy due to collision. Sometimes a part of its energy comes out as a photon and rest is given to the colliding particle of the target. If the electron has a left over kinetic energy it may lose it in the next collision. Sometimes the col..

This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor Vista tutor helped me understand and gave me some practices and showed me how to do them.
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! :)
Looking for More Help!
