What are the to quantities needed in describing the speed of an moving object?
The two quantities needed to describe the speed of a moving object are distance traveled and time taken to cover that distance. Speed is calculated by dividing the distance by the time.
Why are area and speed derived quantities?
Area and speed are derived quantities because they are obtained by combining base quantities. Area is derived from multiplying two length measurements, while speed is derived from dividing a length measurement by a time measurement. These derived quantities are built upon the fundamental base quantities of length and time.
What are derived quantities?
All other quantities which described in terms of base quantities are called base quantities.
What is a pair of scalar quantities?
A pair of scalar quantities are two physical quantities that have only a magnitude or size with no direction. Examples include mass, temperature, and speed. Scalars can be added, subtracted, multiplied, and divided like regular numbers.
Which two measurements are needed in order to calculate the speed of an object in motion?
The two measurements needed to calculate the speed of an object in motion are distance traveled and the time taken to travel that distance. Speed is calculated as distance divided by time.
What are the to quantities needed in describing the speed of an moving object?
The two quantities needed to describe the speed of a moving object are distance traveled and time taken to cover that distance. Speed is calculated by dividing the distance by the time.
What two base quantities are used to measure speed?
Distance and time. Speed is defined as the distance an object travels per unit of time, so these two base quantities are essential for measuring speed.
What two quantities needed to calculate the speed of a car?
You need:* Distance Travelled * Time taken to travel that distance Speed = Distance / Time
What does the unit decibel measure?
The ratio between two quantities, usually quantities that somehow measure power, or intensity (power / area).
What is a ratio between two different quantities?
The ratio between two different quantities is the rate.Usually, the second unit is a measure of time.
Why are area and speed derived quantities?

Area is derived from multiplying two length measurements, while speed is derived from dividing a length measurement by a time measurement. These derived quantities are built upon the fundamental base quantities of length and time.
What two quantities do you need to measure in order to determine density of an object?
mass and volume
What two quantities do you need to measure in order to determine the density of the object?
mass and volume
Why do people developed standard measure?
It is so that two people can agree on the quantities that they are talking about.
What are derived quantities?
All other quantities which described in terms of base quantities are called base quantities.
What is a comparison between two quantities with different unit of measure?
an unknown quantity represented by a letter
What is an equation that relates two or more quantities?
A mathematical formula, such as Speed = Distance / Time for example.
