A hard disk drive (HDD) stores data in magnetic form by magnetizing tiny areas on a spinning disk. It uses an electromagnetic read/write head to read and write data by detecting the magnetic orientation of the areas on the disk.

Are the zeros in 60 kg significant?

Yes, the zeros in 60 kg are considered significant because they indicate the magnitude of the measurement.


Give the rules in identifying significant figures?

1. All non zero digits are significant numbers... e.g 12345, 12 ,3576 and all...! 2. All zeros between two non-zero digits are significant e.g 2007 and 9008...! 3. For numbers less than one zeros directly after the decimal point are not significant e.g 0.001 and 0.057..! 4. A zero to the right of the decimal place and following a non-zero digit is significant e.g 1.725...! 5. All other zeros at the left of a number are NOT considered as significant numbers e.g 0023...!


What are the importance of zeros on a graph in physical science?

Zeros on a graph in physical science represent points where a quantity being measured is equal to zero. They can indicate important values such as equilibrium points, boundaries, or critical thresholds. Zeros can help to identify key features of a system and provide insights into its behavior and properties.


How does the speed of a photon compare to the speed of an EM wave?

Wave length of gamma rays is 10 raised to the power of minus 12. It means that you have 10 raised to 12 waves in case of gamma rays/ meter. Wave length of radio wave is 10 raised to 3. So there is difference of '12' zeros between both of them. But the speed of electromagnetic wave is about 300,000,000 meters/ second. It means that photon travels about 300,000,000 meters/second. So the actual distance traveled by photon in case of radio wave is little more than 300,000,000 meters. So in case of gamma rays the distance traveled by photon is 1,000,000,000,000 *1000 = 1000,000,000,000,000 times that of radio wave per second.


How many significant figures are in the measurement 230kg?

There are 2 significant figures in the measurement 230 kg. The zeros are not significant because they are placeholders.

Where does hard disk information stored?

In magnetic particles on the hard drive disk surface. The drive head reads the magnetic particles and interprets if they are ones or zeros. The head doesn't touch the disk surface but resides about .00005 thousands away from the surface. Just opening the drive housing in an unclean environment can render the drive unusable. It also voids the warranty
