Answer:
The right solution is "28.45%".
Explanation:
The given values are:
and,
At 45,
⇒ 
At 
,
or,
then,
⇒ 
hence,
The isentropic efficiency of turbine will be:
⇒ 
(%)
The thermal efficiency of cycle will be:
⇒ 
(%)
I think it's false because the theory states that electrons flow from negative to positive. Since electrons are negatively charged, it follows that they are attracted by positively charged bodies and repelled by negatively charged bodies.
Answer:
A. voltage
Explanation:
The rate of heat transfer per unit area in a thermal circuit is equivalent to the voltage in an electrical circuit.
This is because, within an electrical circuit the voltage is supplied by a generator, which can be batteries, batteries, or others. The moment the electrical voltage acts within a circuit, it will consist of the gradient of electrical potential between two points, which will cause the electrons to move from the point with the highest concentration to the point with the lowest concentration (similar to the transfer of heat from the thermal circuit) generating the electric current.
