Answer:
Explanation:
Carnot cycle
Carnot cycle have four process
1. Iso thermal expansion
2.Reversible adiabatic expansion
3. Iso thermal compression
4.Reversible adiabatic compression
This is ideal cycle for all work producing devices.All devices have efficiency less than Carnot cycle. Because in Carnot cycle all process is reversible process.
Efficiency of Carnot cycle given as
But temperature must be in Kelvin
So

Answer:
Technician B
Explanation:
Both AWG and metric are sized by cross-sectional area.
Technician A is wrong: 12 gauge wire is larger diameter rated for 20 amps in free air. 18 awg is smaller diameter and typically used for speaker wiring, Class II or low voltage and sub-circuits within appliances.
Answer: A fly wheel having a mass of 30kg was allowed to swing as pendulum about a knife edge at inner side of the rim as shown in figure.

Answer:
False
Explanation:
When you're studying, you need to make sure that you can focus properly. This means that you shouldn't be hungry or too full and that you should be well-rested, in a quiet room with good lighting and no distractions. Noise is never good when you need to memorize something. Some people can partially ignore it as long as it isn't too loud, but it will begin to bother them eventually. That's why it's better to study in a quiet room.
