what is the difference between the circle and disc?

Correctly speaking, a circle has no area (it is just the edge), but a disk does. But in practice people think of a circle as the edge or the enclosed space, or both. A disk is "closed" when it includes the bounding circle, and open if it does not. Also spelled "disc".

The main difference between these types of motion is that circular motion is a special case of rotational motion, where the distance between the body's centre of mass and the axis of rotation remains fixed. Rotational motion is based around the idea of rotation of a body about its center of mass.

DVD drives are not only able to play and write to DVD media, but also CDs. The main difference between CDs and DVDs is the size of available storage. With a CD, you'll get around 700MB at the most. A DVD, on the other hand, will be able to hold just shy of 5GB (4.7GB) worth of data.

There are two physical sizes: 12 cm (4.7 inches) and 8 cm (3.1 inches), both 1.2 mm thick. These are the same form factors as CD. A DVD disc can be single-sided or double-sided. ... For reference, a CD-ROM holds about 650 MB (megabytes), which is 0.64 GB (gigabytes) or 0.68 G bytes (billion bytes).

In Fig. 10.42,AB is a diameter of the circle,CD is a chord equal to the radius of the circle.AC and BD when extended intersect at point at E. Prove that ∠AEB = 60 degree . In Fig.

The bulged disc material is still contained within the annulus. But in some cases, the nucleus pushes completely through the annulus and squeezes out of the disc. This is called a disc herniation or protrusion. Herniation and protrusion are two words for the same thing.

Disc Dimensions DVD and Blu-ray discs have the same measurements as CDs. Discs are standardized and should not vary significantly between brands. Mini CDs are sometimes referred to as “Maxi CDs” in some countries. They hold up to 210MB of storage space and dimensions should not vary significantly between brands.

Difference Between Circle and Sphere. A circle is a closed curved line. Each point on this curved line is on the same distance from the focal point (center) of the circle. ... In simple terms – a circle is a round object in a plane, while a sphere is a round object in a space.

Answer. First know a sphere, it is 3 dimensional figure in round shape & half of this figure is hemisphere. A circle is a 2 dimensional round shaped figure, & half of this 2 D figure is known as semicircle.

Two disc are rotating about their axes,normal to the discs and passing through the centres of the discs. Disc D1 has 2kg mass and 0. 2m radius and initial angular velocity of 50rads−1.

The capacity is the biggest difference between CD and DVD. ... That means you can store CD-quality audio that can last for about 80 minutes or video lasting about 60 minutes. DVD, short for Digital Versatile Disc, is also an optical medium to store digital data. A standard DVD can hold 4.7 GB of data.

Because a circle is a flat, plane shape, it is a face. But because it is round around the outside, it does not form any edges or vertices. A cylinder has two circular faces but also no edges or vertices.

The main difference is that the DVD can store much more data than a CD-ROM, CD-R, or CD-RW. DVD+R is a recordable DVD format similar to CD-R. ... A DVD-R can only record data once, then the data becomes permanent on the disc. The disc cannot be recorded onto a second time.

The disk method is typically easier when evaluating revolutions around the x-axis, whereas the shell method is easier for revolutions around the y-axis---especially for which the final solid will have a hole in it (hence shell). Another main difference is the mentality going into each of these.

A circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.

Circular Functions. ... Whereas trigonometric functions consist of domains that are sets of angles and ranges that are real numbers, circular functions have domains that are sets of numbers that correspond to the angles of the trigonometric functions (in radians).
