If the magnitude of a vector is√8 .If it's x-component is 2 ,then it's y- component is

The answer is below

Explanation:

A vector quantity is a quantity that has both magnitude and direction. The magnitude of a vector is the length of that vector.

The magnitude of a vector a with a x component of x and y component of y is given by the formula:

Given that the vector has a magnitude of √8, the x component is 2 and the y component = y. Hence:

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
