Answer:
The factors of production are resources that are the building blocks of the economy; they are what people use to produce goods and services. Economists divide the factors of production into four categories: land, labor, capital, and entrepreneurship
Differences:
An electrical motor converts electrical energy into mechanical energy,where as a generator converts mechanical energy into electrical energy.
The principle of a electric motor if there is a change of the magnetic field across a conductor electrons are forced to move in a direction perpendicular to the direction of the magnetic field,where as in a generator if a charge is moving in a magnetic field, a force acts on the charge in a direction perpendicular to both the velocity of the charge and the magnetic field.
similarities:
Both electric motor and generator work on the magnetic effects of electric current.
Both have the armatures to rotate the loop.
Answer:
Protium
Explanation: Protium is an isotope of hydrogen that is composed of one proton and one electron. It is the most abundant form of hydrogen.
As the source approaches you, the sound waves are compressed, so
the pitch of the sound is higher than what the source is actually emitting.
Then, after it passes you and begins moving away, the sound waves
are stretched, so the pitch of the sound is lower than what the source
is actually emitting.
