Disk rotation time can be calculated using the formula: Rotation time = (1 / RPM) * 60 seconds. RPM stands for revolutions per minute, which indicates how many times the disk spins in one minute. By taking the reciprocal of the RPM and multiplying it by 60 seconds, you can determine the time it takes for one complete rotation of the disk.

Explain why the material surrounding a young star forms a disk?
The prograde rotation of the collapsing cloud of gas and dust results in conservation of angular momentum, causing the material to flatten into a disk shape. This disk of material, known as a protoplanetary disk, is where planets are thought to form through the process of accretion and gravitational interactions.
Does an accretion disk spin?
Yes, an accretion disk does spin due to the conservation of angular momentum. Material in the accretion disk orbits around the central object, such as a black hole or a star, with velocities that result in rotation or spin.
In the hard disk o track is inner most or outer most?
The outermost track on a hard disk is located closest to the edge of the disk, while the innermost track is located closest to the center. The outer tracks have a higher data transfer rate compared to the inner tracks due to the higher linear velocity of the disk's rotation at the outer edge.
What is the role of rotation in the process of stellar birth?
Rotation plays a key role in the process of stellar birth by influencing the collapse of a molecular cloud into a protostar. As the cloud collapses, conservation of angular momentum causes it to spin faster, forming a protostellar disk. This disk is where material accumulates to fuel the growth of the protostar.
The is caused by the earths rotation?
Earth's rotation is slowing slightly with time; thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth's rotation.
What is gained by increasing the rotation speed of a disk or CD?
increase tranfer rate and decrease average access time
What measures the rotation of platters in the hard disk?
arc measure
What processes caused the formation of a disk around a young star?
Rotation
The current platter rotation rate of a modern hard disk drive is?
7200rpm
Why accessing of data in magnetic tape is slower than hard disk?
tape : seek time for a record requires moving the tape through the drive until the record's location is found, average seek time will be half the time needed to move the entire tape through the drive; a tape that takes 10 minutes to move all the way through the drive will have an average seek time of 5 minutes.disk : seek time for a record requires stepping to the track that holds the record then waiting no more than one disk rotation for the record, average seek time is the sum of the time to step halfway across the disk and the time for the disk to make half a rotation; a disk with 1000 tracks with a 2 ms step time that rotates 100 times per second (10 ms per rotation) has an average seek time of 500 * 2 ms + 5 ms = 1005 ms = 1.005 secondsThe above given numbers are for illustration only and do not correspond to any specific real device,
Does rotation and time have a connection?
Yes, the rotation of the earth does have a connection with time.
What happens to the rotation of a molecular cloud as it collapses to form a star?
The rotation of a molecular cloud tends to increase as it collapses to form a star due to the conservation of angular momentum. This rotation can lead to the formation of a protostellar disk around the young star, influencing the subsequent evolution of the star and potentially contributing to the formation of planetary systems.
How do the motions of the sun and planets reflect the disk shape of the solar nebula?
The motions of the Sun and the planets reflect to disk shape of the solar nebula because they follow the same rotation as this disk shape. The rotation of the Sun and the planets is not a perfect circle.
What is Jupiters rotation on its axis time?
What is planet Jupiter's rotation on axis time
What planet has the most rotation time planet has the most rotation time?
Venus
Hard disk has a rotation speed of 7200RPM then the latency time is?
it depends on more then rotational speed. The Rotational speed and latency time is related as follows: Latency time = (1/((Rotational Speed in RPM)/60)) * 0.5 * 1000 milli seconds
Can Xbox 360 GAME work in Xbox?
no they have different disk rotation speed and different hardware requirements
