Answer:
C. Theories
Explanation:
Theories basically explain why of research findings. By definition, theories help us understand, explain, and predict the occurrence of a phenomena. In research, theories support research findings by explaining how the variables involved influence each other not merely based on observation during this one experiment. It also helps validate the findings by relating it to theories of previous work.
Answer:
Explanation:
According to Coulomb's law, the magnitude of the electric force between two equals charges (q) is given by:
Here k is the coulomb constant and d is the distance between the charges. For two electrons we have:
Answer:
a) 1511 MW
b) 44%
Explanation:
The thermal power will be the electric power plus the heat taken away by the cooling water.
Qt = P + Qc
The heat taken away by the water will be:
Qc = G * Cp * (t1 - t0)
The Cp of water is 4180 J/(kg K)
The density of water is 1 kg/L
Then
G = 1.17 * 10^8 L/h * 1 kg/L * 1/3600 h/s = 32500 kg/s
Now we calculate Qc
Qc = 32500 * 4180 * (29.8 - 23.6) = 842*10^6 W = 842 MW
The total thermal power then is
Qt = 669 + 842 = 1511 MW
The efficiency is
η = P / Qt
η = 669 / 1511 = 44%
