Answer: I think the answer is 3.) Krypton or Argon.
Explanation:
Answer:
17 ohms
Explanation:
Given that,
In a series circuit there are 17 light bulbs, each providing 1 ohm of resistance.
We need to find the total resistance of the circuit.
The equivalent resistance for series combination is given by :

For 17 light bulbs, the equivalent resistance is given by :

Hence, the total resistance is 17 ohms. Hence, the correct option is (d).
For what? what is your question
Physical. When you simply desolve something with water, to don't actually change it. This action can be undone.
An example of a chemical reaction is when the cells within completely change. You you burn wood, you can't go back in time and un-burn it. Does that make sense?
