Answer:
mechanism of energy transfer in system is depend on Heat and Work:
Explanation:
Heat :Heat is described as the type of energy transmitted by a temperature difference between two structures (or a system and its environment).
Work:it is is an interaction of energy between a system and its environment. In the form of work it can cross the boundaries of a closed system. if energy crossing boundary of the system is not heat then it must be work..

Explanation:
Think of brushes as a sliding contact.
In an alternator the brushes provide power to the field coil which is physically mounted on the rotating shaft. They provide this direct current through two slip rings.
By controlling the power flow to the field, the power output of the alternator can be controlled. A regulator circuit is used to control the field so that the output voltage is maintained to about 13.5 to 14.5 VDC.
FUN FACT: Many brush holders have a small holes near the brush exit. When you assemble the alternator you physically push the brushes all the way into their holder and then thread a small wire through these hole. After the alternator is assembled you can pull the wire out and the brushes will snap into position.

Explanation:
Melt spinning is the economical process to manufacture synthetic fiber.
Major limitations of Melt spinning is
- only suitable for thermoplastic fiber
- High heat input
- Require periodic maintenance of machine
- Precise control of temperature is must.
Although it is very efficient method as it does not create any environment Pollution
