Answer:
Since the maximum thermal efficiency is higher than 55 percent, there can be a power cycle with these reservoir temperature with an efficiency higher than 55 percent.
Explanation:
The maximum thermal efficiency is determined from the given temperature
nth Carnot = 1- TL/TH
Where TL= 17+273= 290k
TH= 627*273= 900K.
nth Carnot = 1- 290/900 = 0.68
0.68*100 = 68 percent
La respuesta es 3 ohmios
Resistencia total = (1/12 + 1/4) ⁻¹
= (1/3) ⁻¹
= 3 ohmios
Por ejemplo, dos resistencias, R1 y R2 están en serie, la resistencia combinada es R1 + R2.
Cuando se conecta en paralelo, la resistencia total es el recíproco de (1 / R1 + 1 / R2)
En este caso las resistencias están en paralelo
Espero que esto ayude, que tengas un día bendecido!
The answer is A. subduction
Power = (voltage) x (current)
If the camcorder is USING 14 watts of electrical power right now, then . . .
14 watts = (2 volts) x (current)
Divide each side by (2 volts):
Current = (14 watts) / (2 volts)
Current = (14 V-A) / (2 V)
<em>Current = 7 Amperes</em>
