Answer:
It violates neither of them
Explanation:
first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another.
As we can see, 100MW work and temp of 500K was initial.
Now, the summation of output and lost work and temp = 70MW and 300k, do it doesn't violates first law.
The Second Law of Thermodynamics says that processes that involve the transfer or conversion of heat energy are irreversible, from the question, it is irreversible.
Answer:
Explanation:
The change in potential is then defined as the negative of the work done by that force. ... You can't have work done by gravity AND a change in gravitational potential energy. You have to do it one way or the other. This means that the most important step in solving work-energy problems is choosing a system.
the phenomenon is An object that has potential energy can transfer that energy into kinetic energy when the object begins to move, due to its mass or position. For example, a person jumping on a trampoline has potential energy when they reach the peak of a jump, and their force changes direction from upward to downward.
Answer:
1. False
2. True
3. True
Explanation:
1- False —> The relation between electric potential and electric field is given such that
Therefore, for a uniform E field, electric potential is linearly proportional to the distance.
2- True —> The electric field lines always cross the equipotential lines perpendicularly.
3- True —> In order to be a potential difference, one source of electric field is enough. The electric potential will decrease radially according to the following formula:
There is no test charge in the formula, only the source charge. Even when there is no test charge, the potential difference between points in space can exist.
10 cm
you can see the distance from peak to peak or the distance between the starting point to the end of the first whole wave
Quantum dots are crystals of a fluorescent semiconductor material with a diameter of as few as 10 to 100 atoms. They are used as labels for imaging molecules because of their very narrow fluorescence, brightness, and resistance to photobleaching.
This is the most recent information I could find.
I hope this helps:)
