Answer:

6.6 Joules

Explanation:

Energy = power * time

= V*I*t

= 3.7 * 1.8

= 6.6 Joules

Answer:

E=23,976 J

Explanation:

Given that

I = 1.8 Ah

Voltage =  3.7 V

We know that 1 h = 3600 s

I = 1.8 x 3600 A.s

I=6480 A.s

The energy in Jules given as

E= V. I  

We know that unit of V.I is Watts ( J/s) and when multiple by seconds then we get Joules.

E=3.7 x 6480 Watt.s

E=23,976 J

Therefore the energy in joule will be 23,976 J.

What is the area enclosed by the cycle area of the Carnot cycle illustrating on a P-V diagram?
Inga [223]

Answer:

The work of the cycle.

Explanation:

The area enclosed by the cycle of the Pressure-Volume diagram of a Carnot engine represents the net work performed by the cycle.

The expansions yield work, and this is represented by the area under the curve all the way to the p=0 line. But the compressions consume work (or add negative work) and this is substracted fro the total work. Therefore the areas under the compressions are eliminated and you are left with only the enclosed area.
