A chemical symbol designates an element that belongs to the periodic table.
A chemical formula combines two or more symbols and it represents a chemical compound. We notice that the chemical symbols are followed oftenly by a subscript that represents the mole proprtions of next element.
Answer:
The correct option is (c).
Explanation:
Electromagnetic waves are created as an interaction of the electric field and a magnetic field.
The characteristics of a wave are amplitude, frequency, speed and wavelength. It term defines a wave.
All the electromagnetic wave moves with a common speed i.e. the speed of light.
Hence, all electromagnetic waves move at the same speed.
I think the answer would be the last option. The difference between the energy transformations in power plants and dams would be that dams are the ones who uses mechanical energy to produce electricity. It uses turbines to convert mechanical to electrical.
