physical significance of's orbital

The significant figures are all those digits which we are absolutely sure of plus those digits that we are not sure of. However, the digits have a meaningful value. This also provides us with information about the extent of uncertainty in measurement. E.g., All the experiment..

Remote Sensing - The cameras used on Landsat satellites are extremely complex. They use a process called remote sensing, in which the cameras scan the earth to look for different patterns of radiation. The Landsat cameras view the earth both in visible light, and also in infrared radiations. A sing..

To land people on the moon and return them to earth, requires very powerful and reliable rockets. The US made use of Saturn-V rocket that gave the necessary boost for the Apollo spacecraft. Apollo spacecraft consists of three parts: the Lunar Module the Service Module the Command Module Assembly of..

Multiplication of Vectors by Real Numbers, i.e., Scalar Multiple of a Vector - The multiplication of a vector by a real number assumes a lot of significance in such statements as - velocity of car B is double the velocity of car A l . When a vector is multiplied by a real number, say l , ..

.e., facsimile of printed matter or pictures) use a similar mechanism. In the case of intercontinental telecommunication, two or more satellites are linked together. High frequency radio and submarine cable systems have been widely used for long- distance overseas telecommunications. The high frequ..

.I. Unit of Z is kg/coulomb (kg C -1 ). 2. When the same amount of charge is made to pass through any number of electrolytes, the masses of the substances liberated or deposited at the electrodes are proportional to their chemical equivalents. i.e., if m 1 and m 2 are the masses and E 1 and E 2 are..

The displacement takes place in time D t. The average velocity of the particle is given by The instantaneous velocity is given by The instantaneous velocity vector is always tangential to the trajectory at the point that locates the particle position. Next, let us understand the significance..

> How do infrared and g - rays differ in their (i) wavelength and (ii) penetrating power. Suggested Answer:- (i) g - rays have much shorter wavelengths of the order of 10 - 1 3 m while the infrared have longer wavelengths of the order of 10 - 6 or more. (ii) g - rays have a much higher penetrating ..

Uniform Circular Motion - The revolution of moon around the Earth and the revolution of an artificial satellite in a circular orbit round the Earth are examples of circular motion. Consider a particle moving with constant speed along the circumference of a circle of radius R in the anticl..

Polar orbits are used to watch the earth. They are the planes perpendicular to equatorial plane. Satellites in polar orbit are low enough to collect the information about earth in detail. Low earth orbit is the easiest and cheapest to reach, lying just above the atmo..
