Answer:
- Fundamental quantities are quantity whose definition does not depend on other quantities.
There are seven fundamental quantities in physics:
Length (measured in metres)
Mass (in kilograms)
Time (in seconds)
Electric current (in Ampere)
Temperature (in Kelvin)
Amount of substance (in moles)
Luminous intensity (in candela)
- On the other hand, derived quantities are quantities that are defined using the fundamental quantities.
For example, derived quantities are:
Velocity, which is the ratio between length and time
Acceleration, which is the ratio between velocity and time
Energy, which is a product of mass and velocity squared
And many others.
I'd Say B :) Your Welcome LOL!!!!!
Which is an example of a chemical change?
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding.
