Did you mean acceleration? “Average acceleration is the final velocity minus the initial velocity per time taken”
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.
Explanation:
Since the bottle of water was inside the refrigerator, it is cooler than the air outside the refrigerator.
There is water vapour in the air which gets cooled by the bottle and changes state from gas to liquid and settles on the bottle.
