    What is the SI unit of time?

    • Minutes

    • Hours

    • Seconds

    • Years

    Correct Answer
    A. Seconds
    Explanation
    The unit of time is seconds. Seconds are a commonly used unit of time in everyday life and scientific measurements. They are used to measure short durations or intervals, such as the time it takes for an event to occur or for an action to be completed. Other units of time, such as minutes, hours, and years, are derived from seconds and are used to measure longer durations. However, seconds are the fundamental unit of time and provide the most precise measurement for shorter intervals.

    What is the SI unit of length?

    • Inches

    • Meter

    • Centimeters

    • Millimeters

    Correct Answer
    A. Meter
    Explanation
    The unit of length is meter. Meter is the standard unit of length in the metric system, and it is used to measure distances and dimensions. It is a fundamental unit of measurement and is commonly used in scientific, engineering, and everyday applications. Meter is a larger unit compared to centimeters and millimeters, and it is equivalent to 100 centimeters or 1000 millimeters.

  • 4. 

    What is the SI unit of temperature called?

    • Volume

    • Fahrenheit

    • Kelvin

    • Celsius

    Correct Answer
    A. Kelvin
    Explanation
    The unit of temperature called Kelvin is used in the scientific community and is based on the absolute scale of temperature. It is commonly used in physics and other scientific disciplines where precise temperature measurements are required. Unlike Celsius and Fahrenheit, Kelvin does not have negative values and is based on the concept of absolute zero, which is the lowest possible temperature.

    The SI prefix meaning 1000 is called?

    • Deci-

    • Centi-

    • Milli-

    • Kilo-

    Correct Answer
    A. Kilo-
    Explanation
    The prefix "kilo-" is used to denote a factor of 1000. It is commonly used in the metric system to represent units that are larger than the base unit. For example, a kilogram is equal to 1000 grams. Therefore, "kilo-" is the correct answer to the question.

    Rate this question:

  • 6. 

    What is mass?

    • The amount of space something takes up.

    • An explanation based on observations and experimentation

    • Weight in pounds of an object

    • Amount of matter in an object

    Correct Answer
    A. Amount of matter in an object
    Explanation
    Mass is a fundamental property of matter that refers to the amount of matter an object contains. It is independent of the object's size or shape, and can be measured using a balance. Mass is different from weight, which is the force exerted on an object due to gravity. The correct answer, "Amount of matter in an object," accurately describes the concept of mass.

    Rate this question:

  • 7. 

    The prefix meaning .001 is

    • Milli-

    • Centi-

    • Deci-

    • Kilo-

    Correct Answer
    A. Milli-
    Explanation
    The prefix "milli-" is used to denote a factor of one thousandth, or 0.001. It is commonly used in the metric system to indicate a smaller unit of measurement. For example, one millimeter is equal to 0.001 meters, and one milligram is equal to 0.001 grams. Therefore, "milli-" is the correct prefix meaning 0.001.

    Rate this question:

  • 8. 

    What is the metric unit of temperature used on thermometers called?

    • Watt

    • Kg

    • Meters

    • Celcius

    Correct Answer
    A. Celcius
    Explanation
    Celsius, also known as degrees Celsius (°C), is the standard metric unit for measuring temperature. It is widely used around the world, except in a few countries like the United States where Fahrenheit is still commonly used. The Celsius scale sets the freezing point of water at 0°C and the boiling point at 100°C under standard atmospheric conditions.

    Rate this question:

  • 9. 

    The prefix meaning 0.1 is

    • Milli-

    • Deci-

    • Centi-

    • Kilo-

    Correct Answer
    A. Deci-
    Explanation
    The prefix "deci-" denotes a factor of 0.1. It is derived from the Latin word "decimus," meaning tenth. Therefore, when used as a prefix, "deci-" indicates a unit that is one-tenth of the base unit. In this case, "deci-" represents a factor of 0.1, making it the correct answer for the prefix meaning 0.1.

    Rate this question:

  • 10. 

    Density is

    • Volume times mass

    • Mass times volume

    • Volume divided by mass

    • Mass divided by volume

    Correct Answer
    A. Mass divided by volume
    Explanation
    Density is a measure of how much mass is contained in a given volume. It is calculated by dividing the mass of an object by its volume. Therefore, the correct answer is "mass divided by volume".
