Answer:
The correct options are;
C. Alternating current and direct current
E. Electrolyte
Explanation:
Electricity is generated in either AC or DC depending on the source of the energy which aids the electricity generation;
The most common method through which electricity is generated and through which the principle of electric generation was discovered by Michael Faraday, is the rotation of a wire loop or coil between the North and South poles of a magnet to produce Alternating Current
Electricity is also generated in Direct Current by solar cells which convert sunlight into electric energy by photovoltaic effect.
20. Electrolysis is a chemical reaction that is brought about by the application or passing of a direct electric current through an electrolyte, which is an ion containing liquid.

Answer:
When the expenditure increased, then the consumer's expenditure is increased to Rs.150 and when the price falls of the good it becomes Rs.5. Then, Good X will be Rs.10.
last question:If the Good X falls by 20%, then, it will be Rs.2, and according to his demand 100 units will be equal to Rs.200.
cause if one unit=rs.2, then 100units=100×2=200.
Radio waves are radiated by charged particles when they are accelerated. They are produced artificially by time-varying electric currents, consisting of electrons flowing back and forth in a specially-shaped metal conductor called an antenna. ... Radio waves are received by another antenna attached to a radio receiver.
