If the force between two 20.0 m-long parallel wires separated by 0.014 m, both carrying 6.6 A in the same direction is 0.0124, what will be the force when the distance between the wires is doubled

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
