Question

magnitude definition in three marks​

Answer 1

$\huge\mathbb{\underline{Answer}}$

• The magnitude is a number that characterizes the relative size of an earthquake.
• Magnitude is based on measurement of the maximum motion recorded by a seismograph.
• All magnitude scales should yield approximately the same value for any given earthquake.

Answer 2

Answer:

Magnitude simply means “how much”. In physics, we use many kinds of numbers, two of which are scalars and vectors. A scalar is a number that only has a magnitude or an amount. For example:

6 bananas

23.5 kilograms

18 meters/second

67 kilometers

A vector is a number that has a magnitude and a direction. For example:

18 meters/second West

67 kilometers Up

12 miles at an angle of 35 degrees

Some scalars can be made into vectors by adding a direction, but only certain things can be vectors since it would make no sense to say 6 bananas down (unless you were using a banana as a ruler - weird!)

hope this will helps u.....
