Answer:
chemical change through chemical process .
physical change means change in dimension.
The total current through the circuit is 0. 19A
<h3>How to determine the current</h3>
We have the formula for power to be;
Current, I = V/R
Voltage = 7. 7V
Resistance in parallel = R1R2/ R1 + r2
Resistance in parallel = = = 41. 40 Ohms
Current = = 0. 19 A
Thus, the total current through the circuit is 0. 19A

Answer:
Part A: 16.1 V
Part B: 20.5 V
Part C: 21.5%
Explanation:
The voltmeter is in parallel with the 4.5-kΩ resistor and the combination is in series with the 6.5-kΩ resistor. The equivalent resistance of the parallel combination is given as
Part A
The voltmeter reading is the potential difference across the parallel combination. This is found by using the voltage-divider rule.
Part B
Without the voltmeter, the potential difference across the 4.5-kΩ resistor is found using the same rule as above:
Part C
The error in % is given by
Answer:
Natural gas
Explanation:
Nuclear is from splitting atoms in a nuclear power plant and doesn't emit GHG.
Hydroelectric is a clean energy which powered by water currents in turn not emitting any GHG.
Geothermal is heat captured from underneath the surface and within Earth and doesn't have GHG once the contruction of putting pipes underground is done.
Natural gas once burned emits GHG.
I believe it is called the Greenhouse effect.
