What is a meniscus in the context of measuring liquids?

Back

A meniscus is the curve at the surface of a liquid in a container, which is used to measure the volume of the liquid accurately. The reading should be taken at the bottom of the meniscus.

What is the base unit for time in the International System of Units (SI)?

Back

The base unit for time in the SI system is the second.

How do you calculate wavelength if you know the distance on the x-axis?

Back

Wavelength can be calculated by multiplying the x-axis interval by the number of cycles or waves.

Front

What does a local index trend represent in data analysis?

Back

A local index trend represents the relative change in a specific dataset over time, often used to analyze performance or growth.

Front

How do you determine the range of a data set?

Back

The range is determined by subtracting the smallest value from the largest value in the dataset.

Front

What is the formula for calculating speed?

Back

Speed is calculated using the formula: Speed = Distance / Time.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, measured in kilograms, while weight is the force exerted by gravity on that mass, measured in newtons.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the formula for calculating density?

Back

Density is calculated using the formula: Density = Mass / Volume.
