Need of drives in motor?
Drives - I assume you are referring to Variable frequency Drives. The drives are useful when a motor needs to rotate at different speeds when in operation with out stopping it.
Why does a day consist of 24 hours?
because that's how long it take for the earth to rotate once
Why does a year consist of 365 days?
thats how long it takes for the earth to rotate around the sun.
What is mean by biquartz?
it is a device which consist of two pieces of quartz of equal thickness which rotate the polarization of light in opposite direction
If a magnetic drive has four platters how many heads does it have?
Each platter on a hard drive has 2 heads.Every Additional Platter you can multiply x2Example:1 Platter x 2 = 2 Heads2 Platters x 2 = 4 Heads3 Platters x 2 = 6 Heads4 Platters x 2 = 8 Heads5 Platters x 2 = 10 HeadsETC...At least until some new hard drive Architecture comes into place.
Explain the working principle of the hard disk drive?
A hard disk uses platters, round discs that are coated with a special media that is designed to store data in magnetic patterns. These discs rotate so that heads, electromagnetic read/write devices, can either record data onto the platters or read what the platters already contain. Each platter has tracks which is then broken down into sectors which is where pieces of data is actually recorded.
Why are there no geometric isomers in non cyclic compounds containing single bonds?
Because atoms are free to rotate freely around a single bond.
The main secondary storage device of a PC a small case that contains magnetic coated platters that rotate at high speeds?
I just got this exact same question for homework in my CS course today, what a surprise. A floppy disk, magnetic coated and rotates.
What are racemic mixtures?
Mixtures containing equal amounts of levo- and dextro- forms of a compound and thus do not rotate the plane of polarized light passing through the mixture.
What drives the flow of water through a sponge?
the sponge absorbs water, and keeps it in. if you rotate or tilt it, the water will move because of gravity.
To turn on an axis?
It's rotate!
What kind of velocity causes a disc to rotate at a constant speed?
Uniform-Pertaining to computers-"Some later CD drives use CLV technology in combination with constant angular velocity (CAV). With CAV, the disc rotates at a constant speed, just as is done with hard drives."(pg 459, A+ Guide to Managing and Maintaining Your PC)
