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:
Explanation:
(a) The production schedule is 4000 hour per year, or 240,000 minutes. In that time, 133,333 1/3 parts can be produced. The production of 500,000 parts in a year will require the use of ...
.5 million/(.1333... million/machine) = 3.75 machines
The demand can be satisfied by 4 machines.
__
(b) If availability is 95% then 3.75/0.95 ≈ 3.95 machines will be required.
The demand can be satisfied by 4 machines.
Answer:
38 kJ
Explanation:
The solution is obtained using the energy balance:
ΔE=E_in-E_out
U_2-U_1=Q_in+W_in-Q_out
U_2=U_1+Q_in+W_in-Q_out
=38 kJ
B) the plates are in constant motion and as a result the boundaries are where they interact
