In a wire with a 1.35 1.35 mm2 cross-sectional area, 5.41 × 10 20 5.41×1020 electrons flow past any point during 2.19 2.19 s. What is the current in the wire?

The current in the wire = 39.53 A.

Explanation:

The given cross -sectional area of the wire  = 1.35 .

The number of electrons flowing in the wire at any point is  

= 5.41 electrons.

The charge of an electron is known to be  =

The electronics flow across the wire for a time of, t = 2.19 seconds.

The current in the wire  = (number of electrons) ×

                                       = 5.41 ×

                                       =  39.53 A.

The formula for current is actually, i =  .  

The (number of electrons )×(charge of an electron) will equal the total charge flowing through the wire in the given time  = 2.19 seconds.

The current in the wire = 39.53 A.

i was thinking more like reflects green light, just not sure

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.
