Answer: Option (a) is the correct answer.
Explanation:
Photosynthesis is defined as a chemical process in which plants tend to make their own food in the presence of sunlight, water and carbon dioxide.
During this process, product formed by the plants is glucose and oxygen.
The chemical reaction equation for photosynthesis is as follows.
Therefore, we can conclude that out of the given options the correct equation is as follows.
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):
Now, you can calculate the unknown resistor R2 by using the equation (1):
hence, the resistance of the unknown resistor is 10.31Ω
