This is true (answer a), but also a very generic, vague statement. Creating a loop of some sort would be an example.
Answer:
200 Ω
Explanation:
Hi there!
Please see below for the circuit diagram.
<u>1) Find the total resistance of the resistors in parallel</u>
Total resistance in parallel equation: 
Both the resistors measure 200 Ω. Plug these into the equation as R₁ and R₂:
Therefore, the total resistance of the resistors in parallel is 100 Ω.
<u>2) Find the total resistance of the circuit</u>
Now, to find the total resistance of the circuit, we must add the 100 Ω we just solved for and the 100 Ω for the other resistor placed in series:
100 Ω + 100 Ω = 200 Ω
Therefore, the total resistance of the circuit is 200 Ω.
I hope this helps!
Answer: D)The pattern of blood vessels at the back of the eye.
Explanation: The retinal scan is the techniques which is used in the bio-metric mechanism.The scanning of the retina's blood vessel pattern is capture by the scanner is the unique technique which is used for bio-metric purpose.
Blood vessel pattern is capture because it is present in unique form for every person and will help in distinguishing a person from another person while scanning.
Other options are incorrect because light reflection or reaching near retina and light pattern are not the unique way for identification while scanning a person.Thus the correct option is option(D).
