Answer:
The wavelength the student should use is 700 nm.
Explanation:
Attached below you can find the diagram I found for this question elsewhere.
Because the idea is to minimize the interference of the Co⁺²(aq) species, we should <u>choose a wavelength in which its absorbance is minimum</u>.
At 400 nm Co⁺²(aq) shows no absorbance, however neither does Cu⁺²(aq). While at 700 nm Co⁺²(aq) shows no absorbance and Cu⁺²(aq) does.
Answer:
R = 12 ohms
Explanation:
It is given that,
Supply voltage is 12 V
Current in the circuit is 1 A
We need to find the resistance of the circuit. Ohm's law gives the relationship between current, voltage and resistance as follows :
V = IR
So, the resistance of the circuit R is 12 ohms.
