Why are icebergs often surrounded by fog? 1. The air is dryer near an iceberg. 2. The evaporation from an iceberg condenses into droplets (fog). 3. An iceberg attracts vapor from the surrounding air.

2. The evaporation from an iceberg condenses into droplets (fog).

Explanation:

Icebergs are often surrounded by the fog because icebergs that float barely to the surface of the water when the moist air passes over the region then it condenses in the region nearby due to the proximity of the cold air near the iceberg and hence there is foggy appearance of the condensed water droplets.

Icebergs are the large hill-like structures of the frozen water that barely float to the surface of the water bodies.

a and b sometimes have a positive value

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
