Answer:
4A
Explanation:
Current is charge per time. So if the second wire delivers twice as much charge in the same amount of time, it must have twice the current.
2 × 2A = 4A
It is because of the high specific heat of water.
Specific heat is the amount of heat needed to change the temperature of unit mass of a substance by one degree.
Specific heat of water is 4.186 kJ/kg K and that of air is 1 kJ/kg K. Thus, a given amount of heat will cause more change in the temperature of air than that of water.
