With constant velocity the disc rotates at a constant speed?
Yes, when an object rotates at a constant velocity, it means that the speed of rotation remains the same. This implies that there is no change in the angular speed or magnitude of the rotation.
How does constant linear velocity and explain how it applies to CD standards?
Constant linear velocity (CLV) means that the disc rotates at a constant speed regardless of where you are on the disc. This is important for CDs because it ensures a consistent data transfer rate, allowing for smooth playback and accurate reading of data. CLV helps to optimize the performance of the CD drive and improve overall user experience with minimal errors or interruptions during playback.
Cd Angular speed?
Angular speed is a measure of how quickly an object rotates around a fixed point and is usually measured in radians per second (rad/s). It is calculated by dividing the angle through which an object rotates by the time taken to complete one full rotation. Angular speed is related to linear speed by the formula: angular speed = linear speed / radius.
A disc weighing 2 kg rolls without slipping over a horizontal plane with a velocity 4 ms1 Find the kinetic energy of the disc?
The kinetic energy of the disc can be calculated using the formula: KE = 0.5 * m * v^2, where KE is the kinetic energy, m is the mass of the disc, and v is the velocity. Plugging in the values: KE = 0.5 * 2 kg * (4 m/s)^2 = 16 J. So, the kinetic energy of the disc is 16 Joules.
What is angular velocity and radial velocity?
Angular velocity is the rate of change of an object's angular position with respect to time, measured in radians per second. It describes how fast an object is rotating around a fixed point. Radial velocity is the component of an object's velocity that is directed along the line of sight, either towards or away from an observer. It is commonly used in astronomy to measure the speed at which a celestial object is moving towards or away from Earth.

What is purpose of angular velocity?
In http://www.answers.com/topic/optical-storage, constant angular velocity (CAV) is a qualifier for the rated speed of an http://www.answers.com/topic/optical-disc-drive, and may also be applied to the writing speed of recordable http://www.answers.com/topic/optical-disc. A drive or disc operating in CAV mode maintains a constant http://www.answers.com/topic/angular-velocity, contrasted with a http://www.answers.com/topic/clv (CLV). When playing back music, a http://www.answers.com/topic/compact-disc (CD) employs CLV to maintain a constant data rate. The motor speed decreases from 495 to 212 rpm as the read head moves away from the center to keep the disc moving past the read head at a constant linear velocity. High speed CD and DVD drives use CAV. CAV was used in the LaserDisc format for interactive titles, as well as special editions of certain films. CAV allowed for perfect still frames, as well as random access to any given frame on a disc. Playing time, however, was cut in half from 60 minutes to 30 minutes. CAV is used with Nintendo GameCube Game Disc and Wii Optical
What is an abrasive disc?
An abrasive disc is a disc which rotates in a mechanical tool, such as a sander.
Define constant linear velocity and explain how it applies to CD standards?
Constant angular velocity of a rotating disk means that, given a stationary base reference line and a zero line on the disk, both extending from the center of rotation to the outside edge of the disk, the periodic change in angle between the two lines remains a constant. Such a disk will have constant angular velocity (CAV) if its rate of rotation or revolutions per minute (RPM) remains constant.While it would be technically possible to have the linear velocity of the disk remain constant by gradually decreasing the speed of rotation as the player head moves across the disk (because the outer paths are longer than the inner ones), this would make things more complicated both for the recording and playback machines, and therefore more expensive.The paths of information on a CD (or DVD) are analogous to the grooves on an LP recording. The recording and playback heads move across the disk (CD or LP) as it rotates. Actually, of course, there is only one spiral path or groove; on an LP, it goes from the outside edge toward the center; on a CD/DVD, it goes in the opposite direction. In deciding on the parameters for the LP and CD, engineers had to involve the amount of data to be recorded and the spacing required to record that data versus the size of the disk, the speed of rotation, the data capacity of the disk material, and the sensitivity of both the recording and playback heads. ---- The above answer defines Constant Angular Velocity (CAV), not Constant Linear Velocity. The following is the definition to Constant Linear Velocity (CLV): "Constant Linear Velocity (CLV) is a CD-ROM (Compact Disc - Read Only Memory) format in which the spacing of data is consistent on the CD, but the speed of the disc varies on whether the data being read is near the cent or the edge of the disc." During CLV, in order to create the effect of constant speed as the CD turns, the CD drive uses a mechanism that slows down the disc when the laser beam is near the center of the disc, and speeds up the disc when the laser beam is near the outer edge. Thus, the beam is over a sector for the same amount of time, no matter where the sector is.
Why disc in microwave oven rotates at slow speed?

A single speed CD-ROM drive transfersdata at what rate?
150 KB/s.Reference:The first generation of "single-speed" CD-ROM drives were based on the design of audio CD drives, employing constant linear velocity (CLV) technology to spin a disc at the same speed as an audio CD which, with error correction, meant 150 KBps.Source: http://www.pctechguide.com/32CD-ROM_CLV.htm
How do you define constant angular velocity?
Assuming you mean "Constant angular velocity", let's break it down. Constant, meaning "something that does not or cannot change or vary". Velocity is distance over time, or "speed". Angular velocity is the angular distance (such as "one rotation") An example of velocity would be 60 Miles per Hour (MPH). That would be that in one hour, an object would travel 60 miles. An example of angular velocity would be 45 Degrees per Hour. For a real world example, Earth turns 1 full revolution every day. "1 revolution per day" is an angular velocity. Lets convert this to a different unit. There are 360 degrees in 1 revolution. Therefor, we can say that Earth has an angular velocity of 360 degrees per day." We can convert this unit again. There are 24 hours in one day. 360 divided by 24 = 15 degrees per hour, which is another example of angular velocity. Simply put, angular velocity is the speed at which something is rotating. In computers, angular velocity is commonly used to describe a mechanical hard disk drive. Hard drive speeds are measured in Rotations per Minute (RPM) and are commonly 4200, 5200 or 7200 RPM. The faster the speed of the hard drive, the faster it can read and write data.
