charge = current * time
q = 15 * 300 [5 min = 300 sec ]
q = 4500 C
Answer AND Explanation:
Fossil fuels are a type of naturally non-renewable energy sources that are formed from the remains of living organisms. The non-renewable resources are those that are not regenerated in nature at rates equivalent to their use. Fossil fuels have been used by man on a small scale for a long time. The main forms of fossil fuels are petroleum oil, natural gas and coal. Coal forms the major bulk of the fossil fuel deposits.
To solve this problem we must resort to the Work Theorem, internal energy and Heat transfer. Summarized in the first law of thermodynamics.
Where,
Q = Heat
U = Internal Energy
By reference system and nomenclature we know that the work done ON the system is taken negative and the heat extracted is also considered negative, therefore
Work is done ON the system
Heat is extracted FROM the system
Therefore the value of the Work done on the system is -158.0J
Answer:
The correct option is B
Explanation:
Although, it is common knowledge that in an electric field, unlike charges attract and like charges repel. However, to build up an electric potential, a positive charge is brought close to another positive charge - this causes work done to be changed to electric potential energy and stored in the electric field.
It should however be noted that when a negative charge is moved away from a positive charge, the negative charge gains electric potential energy.
