Answer:
1. The length of the wire is halved.
the resistance of a conductor is directly proportional to it's length (L) as R - L. Thus doubling it's length will double it's resistance, while halving it's length would halve the resistance. Also the resistance of a conductor is inversely proportional to it's cross sectional area.
2. The area of cross-section of the conductor in increased.
On increasing the area of cross-section, resistance decreases. Thus is because resistance is inversely proportional to area.
3. The temperature of the conductor is increased.
With increasing temperature, the resistance of the wire increases as collisions within the wire increases and "slow" the flow of current... Since conductors typically display an increased resistivity with temperature increase, they have a positive temperature coefficient.

Answer:
I think the answer is B. Carbon atom but I'm not 100% sure. Sorry if it's incorrect.
Answer: 2116.8 seconds
Explanation:
0.0035 weeks × 7days/week × 24hrs/day × 60min/hr × 60sec/min
=2116.8 seconds
=2100 (if you are required to consider significant figures)
