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: 9.9KJ
Explanation: Q = U + W + losses
Q is heat transfered to the water
U is the change in energy of the system
W is work done by the system = 2J
Losses = 80J
Heat into system is 10kJ = 10000KJ
Therefore
U = Q - W - losses
U = 10000 - 2 - 80 = 9990J
= 9.9kJ
Answer:Yes,266.66 MPa
Explanation:
Given
Yield stress of material =140 MPa
Cross-section of 
Force(F)=8 MN
Therefore stress due to this Force(
)
Since induced stress is greater than Yield stress therefore Plastic deformation occurs
Answer: the correct answer is D
