Answer:
2.80 MJ
Explanation:
(a) We want to calculate the energy U of the battery, where its voltage is E = 13.0V and the supplied current is I = 60 A. We can neglect the internal resistance, so the terminal voltage equals the emf of the battery V = 13.0V. The quantity of delivered energy is given by the rate at which energy is delivered to it in a certain time t. We could obtain the rate at which energy is transferred by using equation , where the rate represents the power P = IV. Therefore, the energy produced is given by
U = P*t (P = IV)
U = I*V*t (1)
Now we can plug our values for I, V and t into equation (1) to get the energy produced in time t = 1 h = 3600 s
U = I*V*t = (60 A)(13 V)(3600s) = 2.80 MJ
Answer
the concentration of electron/ volume (n) = 8.5 × 10²⁸ /m³
the drift velocity of electron
v = 2.615 × 10⁻⁴ m/s
time require is
t = 3231.35 s
Answer:
C)It would require more energy to change solid water into liquid water because there are more molecules in this larger piece of ice.
Explanation:
Total Resistance: 3+2 = 5 ohms
V=9V
Power = V²/R
=9²/5
=81/5
=16.2 W
Answer: 25 km
Explanation: If it travels 25 km in 1 hour it is going 25 km/h meaning if its speed doesn't change for the next hour it will go another 25 km.
