A magnetic domain is a region within a magnetic material in which the magnetization is in a uniform direction. This means that the individual magnetic moments of the atoms are aligned with one another and they point in the same direction.

A computer system consists of a computer case, a power supply unit, a motherboard, a central processing unit (CPU), main memory, and a hard disk drive.

Input devices include a keyboard, mouse, microphone, video camera, and image scanner.

Output devices include a monitor, speakers, and a printer.

A point has no dimension and a line has one dimension is the statement that best compares a line and a point.

The name given to the bond between water molecules is a hydrogen bond. These bonds occur between the slightly negative oxygen of one water molecule and the slightly positive hydrogen of another water molecule. Hydrogen bonding gives water special physical properties.

The differences in electronegativity between hydrogen and oxygen lead to an unequal sharing of electrons. Electronegativity measures how strongly an atom attracts electrons. Oxygen, with its higher electronegativity, pulls on the shared electrons more, giving the oxygen atom a partial net negative charge. The shared electrons spend less time with the hydrogen atoms; therefore, the hydrogen regions of water have partial positive charges.

A metalloid is any chemical element which has properties in between those of metals and nonmetals, or that has a mixture of them.

The six commonly recognised metalloids are

boron,

silicon,

germanium,

arsenic,

antimony, and

tellurium.

I am Keyboard.

A Keyboard has keys of letters, space button and enter button.

12% of 70,000

=> 12 x 70,000/100

=> 8400

Hence, 12% of 70,000 = 8,400

According to BODMAS rule,

After multiplication only, addition is done.

Hence,

5 + 2 x 10 = 5 + 20 = 25.
