Answer:
Option B
Explanation:
The fundamental quantities are the basic quantities from which other quantities are derived.
There are a total of 7 fundamental quantities, namely Length, Mass, Time, Luminous Intensity, Amount of substance, Electric Current, Temperature.
From these 7 quantities, the other quantities are derived.
Weight is the product of its mass and the gravitational acceleration 'g' which acts on that mass.
Where mass is the fundamental quantity and 'g' is also derived and hence weight is a derived quantity.
Velocity = displacement / time
displacement = velocity × time
d = 29 ms⁻¹ ˣ 8.4 s
d = 243.6 m
Electrons are the right subatomic particle
Answer:
A
Explanation:
Kinetic energy is the energy of an object that is moving, so D is immediately out as it is potential energy. A baseball flying at 90 mph has the greatest amount of kinetic energy because it has a higher speed.
