Electrical energy is the starting and final energy of a battery
Answer:
As = 7.33 [m/s]
Explanation:
To solve this problem we must use the definition of the average speed, which is equal to the relationship between the distance over time.
As = x/t
where:
As = average speed [m/s]
x = distance = 132 [m]
t = time = 18 [s]
As = 132/18
As = 7.33 [m/s]
Answer:

Explanation:
The difference of pressure is given by gauge pressure:



In parallel, neither resistor knows about the other one, and they have no effect on each other.
Each resistor is connected straight to the battery terminals. If the battery is hefty enough, it supplies current to each resistor as if the other one weren't there.
Current through a resistor = (voltage across it) / (its resistance).
Current = (20 V) / (40 ohms)
Current = 1/2 Ampere.
