that would be the energy from the core. because of the fact that ht eearths core is producing 45mill killawhats and giggawats
Answer:
See the explanation below.
Explanation:
If you connect the three bulbs 20 W each will have a total power of 60W.
Now we need to understand to assign the meaning of the word gap, that is, if the circuit is open at that point or if there is no bulb connected at that point.
If the circuit is open at Point 2, there will be no current in the circuit, so the battery will drain faster with the three bulbs 20W.
In the second event, where gap means that there are no bulbs connected at that point, it means that you have two bulbs connected in series of 80W each.
In this case the bulbs will consume 160W thus drain the battery faster than the three 20W bulbs connected in series.
Answer: If mass remains constant and you double the force you will double the acceleration.
"Increase in internal energy = energy consumed by fan " as the room is perfectly insulated and sealed.
energy consumed by fan = power x time
power of fan = 4HP = 4 x 745.7 W = 2982.8 W
time = 1.5 hours = 1.5 x 60 x 60 = 5400 s
energy consumed by fan = 2982.8 x 5400 = 16107120 J = 1.61x10^7 J
Increase in internal energy is 1.61x10^7 J
