Avertical straight wire carrying an upward 24-a current exerts an attractive force per unit length of 88 x 104n/m on a second parallel wire 7.0 cm away. what current (magnitude and direction) flows in the second wire?

The current flows in the second wire is

Explanation:

Given that,

Upward current = 24 A

Force per unit length

Distance = 7.0 cm

We need to calculate the current in second wire

Using formula of magnetic force

Where,

=force per unit length

I₁= current in first wire

I₂=current in second wire

r = distance between the wires

Put the value into the formula

Hence, The current flows in the second wire is

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
