Measures Of Quantitative Assessment (Metrics) Quiz

The base unit of the metric system for length is the meter. It is defined as the distance traveled by light in a vacuum in 1/299,792,458 of a second. The meter is used to measure small distances, such as the length of a pencil, as well as larger distances, such as the height of a building or the length of a road. It is a fundamental unit of measurement in the metric system and is widely used in scientific and everyday applications.

The liter is the base unit of the metric system for volume. It is a unit of measurement for liquid capacity and is equal to one cubic decimeter. It is commonly used for measuring the volume of liquids such as water, milk, and gasoline. Other units of volume in the metric system, such as milliliters and cubic meters, are derived from the liter.

The gram is the base unit of the metric system for mass. It is a unit of measurement used to quantify the amount of matter in an object. The metric system is based on powers of ten, and the gram is the fundamental unit for measuring mass in this system. It is smaller than a kilogram and is commonly used for measuring small amounts of mass in everyday situations.

The prefix "centi" represents a fraction of 1/100 or 0.01. In the metric system, prefixes are used to indicate multiples or fractions of the base unit. In this case, "centi" indicates a fraction of one hundredth, making it the correct prefix for 0.01.

The prefix for 1000.0 is "kilo". In the metric system, "kilo" represents a multiple of 1000. Therefore, when we say "kilogram," for example, we mean 1000 grams. In this case, "kilo" is the appropriate prefix for 1000.0.

The prefix for 0.000001 is micro. In the metric system, micro is the prefix that represents one millionth (1/1,000,000) of the base unit. Therefore, when we have a value of 0.000001, it can be expressed as 1 micro unit.

To convert kilometers to centimeters, you need to multiply the given value by 100,000. In this case, 0.21 km multiplied by 100,000 equals 21,000 cm.

To convert milliliters (ml) to liters (l), you divide the value in milliliters by 1000. In this case, 12.0 ml divided by 1000 equals 0.012 liters.

The relationship between ml, g, and cc is that 1 ml is equal to 1 g and 1 cc.

The correct answer is 1.3796 x 10e7. This is because scientific notation is used to express very large or very small numbers in a more concise form. In this case, 13,796,000 is converted to 1.3796 and the exponent is 7, indicating that the decimal point is moved 7 places to the right. This results in a number that is 10 million times larger than the original number.

The given number, 0.00023, can be expressed in scientific notation as 2.3 x 10^-4.

The given question asks to convert 10 ml to g and cc. The correct answer states that the conversion is 10 g and 10 cc. This is because the density of water is 1.00, which means that 1 ml of water weighs 1 g. Therefore, 10 ml of water would weigh 10 g. Additionally, 10 ml is equal to 10 cc, as 1 ml is equivalent to 1 cc.

To convert grams to milligrams, you need to multiply the given value by 1000 since there are 1000 milligrams in 1 gram. Therefore, 2.7 grams is equal to 2700 milligrams.

The relationship between volume and mass in the metric system is that 1 milliliter (ml) is equal to 1 gram (g). This means that the volume and mass of a substance are equivalent in the metric system.

The correct answer is 2.32 x 10. This is because when converting a number to scientific notation, we want to express it as a number between 1 and 10 multiplied by a power of 10. In this case, 23.2 can be written as 2.32 x 10, where the exponent is 1.
