Hint: It indicates the unit in the metric system which is based on a limited set of base units. In mathematical terms, the prefix mega can be defined in powers of ten such that mega denoted ten to the power of six.
Complete answer: First, let us understand the definition of mega in the metric system. Mega denotes a unit prefix that is used in the metric systems of units such that it denotes a ten to the power six i.e. (1,000,000). It implies that mega denotes a million times and is represented by the symbol ‘M’. We already know that most of the units used in science are metric units.
The most commonly used measurements are:
-the mole (amount),
-the liter (volume),
-the gram (weight),
-and the meter (which measures length or distance)
So, the smaller and larger units are just formed by adding prefixes to these units.
Additional information:
Some common usage of prefix mega are as follows:
-Camera: Megapixel is referred to as one million pixels in a digital camera
-In radio and television broadcast, megahertz is used to measure the frequency of electromagnetic radiation. 1MHz = 100,000 Hz.
-In power plants and electricity, Megawatt is used to measure the output of power plants, data centres, the power consumption of electric locomotives, and other purposes that heavily consume electricity.
Therefore, (A), a million times is the correct answer.
Note: In 1960, the prefix-mega was set for use in the International System of Units (SI). The SI unit is the abbreviation of the French name Le Systeme International d’Unites
