The initial equivalent resistance of the circuit is
which means
Therefore the initial current in the circuit is
When the new resistor of
is added to the circuit in parallel, the new equivalent resistance of the circuit is
from which we find
This means that the equivalent resistance of the circuit has decreased, and the new current is
which means that the current in the circuit has increased.
Answer:
1. A. is louder or softer
2. B. Has a different speed
Explanation:
Sorry if any or both are wrong
Answer:
The jp2003parker guy is extremely wrong
So he says that the size wont matter and a physical change should occur, but how would the size change without having a physical change occur.
Explanation:
Answer:
The work required to cause this volume change is 2 x 10⁶ J
Explanation:
Given;
constant pressure of the gas, P = 100 kPa = 100,000 Pa
change in volume of the gas, ΔV = 20 m³
The work required to cause this volume change is calculated as;
W = PΔV
Substitute the given values and solve for the required work (W).
W = (100,000)(20)
W = 2 x 10⁶ J
Therefore, the work required to cause this volume change is 2 x 10⁶ J
