Answer:
R2 = 10.31Ω
Explanation:
For two resistors in parallel you have that the equivalent resistance is:
(1)
R1 = 13 Ω
R2 = ?
The equivalent resistance of the circuit can also be calculated by using the Ohm's law:
(2)
V: emf source voltage = 23 V
I: current = 4 A
You calculate the Req by using the equation (2):
![R_{eq}=\frac{23V}{4A}=5.75\Omega](https://tex.z-dn.net/?f=R_%7Beq%7D%3D%5Cfrac%7B23V%7D%7B4A%7D%3D5.75%5COmega)
Now, you can calculate the unknown resistor R2 by using the equation (1):
![\frac{1}{R_2}=\frac{1}{R_{eq}}-\frac{1}{R_1}\\\\R_2=\frac{R_{eq}R_1}{R_1-R_{eq}}\\\\R_2=\frac{(5.75\Omega)(13\Omega)}{13\Omega-5.75\Omega}=10.31\Omega](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BR_2%7D%3D%5Cfrac%7B1%7D%7BR_%7Beq%7D%7D-%5Cfrac%7B1%7D%7BR_1%7D%5C%5C%5C%5CR_2%3D%5Cfrac%7BR_%7Beq%7DR_1%7D%7BR_1-R_%7Beq%7D%7D%5C%5C%5C%5CR_2%3D%5Cfrac%7B%285.75%5COmega%29%2813%5COmega%29%7D%7B13%5COmega-5.75%5COmega%7D%3D10.31%5COmega)
hence, the resistance of the unknown resistor is 10.31Ω
Answer:
Increases the greenhouse effect and increases the absorption of radiation
Explanation:
An increase in carbon dioxide increases the greenhouse effect and increases the absorption of radiation emitted from Earth's surface. Carbon dioxide has the ability to absorb radiation emitted from Earth's surface. This is because carbon dioxide is an effective heat trapping greenhouse gas.
