Answer:
Because each color is refracted differently, each bends at a different angle, resulting in a fanning out and separation of white light into the colors of the spectrum.
Let me think about this........ correct me if I am wrong.......
Laws of thermodynamics
1) Energy cannot be created nor destroyed. It is transferred.
2) All spontaneous reactions will increased the entropy of the universe (More disorder)
3) The entropy of the crystal lattice structure at 0 K is zero
PE(coal) --> Steam(K.E) ................ This will increase entropy and also conversion of energy. So BOTH LAWS is my final answer.
Wait...... I would like to use a lifelines...... I want to phone my Physical chem professor.
*Ring Ring.........*
Me: Hello, I wanted to make sure if I got the correct answer.
Chem prof: You dont need my help, since you got the right answer.
Me: WOOT!!!!!!!
Answer:
B. A magnet being moved into or out of the coil
Explanation:
Faraday law of electromagnetic induction states that when there is change in flux , an emf is produced . Among the given instances , only in case of B , flux is changing . So current will be induced in the coil . We shall see how it takes place .
A wire carrying constant current will produce magnetic flux in nearby coil but there is no change in flux because current as well as position of wire with respect to coil are not changing .
Passing of magnetic field through a stationary coil produces flux in the coil but here too there is no change in flux so no current will be induced .
A magnet positioned near a coil creates magnetic flux in the coil but the magnitude of flux remains constant so no change in flux and no creation of induced current .
the ability to use an applied force to make an object move
Explanation:
The scientific definition of energy that relates it to work is the ability to use an applied force to make an object move.
- Energy is defined scientifically as the ability to do work.
- Work done is the force applied to make an object move in a specific direction.
Work done = Force x distance
- Since energy is the ability to do work, we are are correct to say energy is also the ability to use an applied force to make an object move.
