Measurement Techniques Assessment

What is the standard unit for measuring length in the metric system?

• meter

• centimeter

• kilometer

• millimeter

How do you convert meters to centimeters?

• Divide the number of meters by 10.

• Subtract 100 from the number of meters.

• Add 100 to the number of meters.

• Multiply the number of meters by 100.

What instrument is commonly used to measure pressure?

• Manometer

• Altimeter

• Barometer

• Thermometer

What is the unit of pressure in the International System of Units (SI)?

• Torr (T)

• Pascal (Pa)

• Atmosphere (atm)

• Barometer (Bm)

How do you measure the length of a curved object?

• Measure the length using a ruler without considering the curve.

• Use a flexible measuring tape or string to follow the curve and measure its length.

• Estimate the length by comparing it to a straight object.

• Use a protractor to measure the angle of the curve.

What is the difference between absolute pressure and gauge pressure?

• Absolute pressure is always higher than gauge pressure.

• Gauge pressure is the total pressure exerted by a fluid.

• Absolute pressure is measured in a vacuum.

• Absolute pressure = Gauge pressure + Atmospheric pressure.

Which tool would you use to measure the height of a building?

• Tape measure

• Compass

• Protractor

• Theodolite or laser rangefinder

What is the formula for calculating pressure?

• P = F * A

• P = A/F

• P = F/A

• P = F + A

How can you measure the length of a liquid in a graduated cylinder?

• Use a ruler to measure the diameter of the cylinder.

• Estimate the volume based on the color of the liquid.

• Measure the height of the liquid from the top of the cylinder.

• Read the measurement at the bottom of the meniscus at eye level.

What is the significance of using a caliper for measuring length?

• The significance of using a caliper for measuring length is its ability to provide precise and accurate measurements of various dimensions.

• Calipers are only effective for measuring large objects.

• Calipers are primarily used for measuring weight.

• Calipers provide measurements that are always rounded to the nearest whole number.
