Meteor Showers and their. Relation to Comets. Meteors (or shooting stars) are very different from comets, although the two can be related. ... The dust and gas are pushed away from the Sun by the solar wind and radiation pressure, producing the comet's tail (which always points away from the Sun, by the way).
City B is at a higher temperature because as you go higher in altitude the boiling point of water becomes lower.
Answer : The current passing between the electrodes is, 
Explanation :
First we have to calculate the charge of sodium ion.

where,
q = charge of sodium ion
n = number of sodium ion = 
e = charge on electron = 
Now put all the given values in the above formula, we get:

Now we have to calculate the charge of chlorine ion.

where,
q' = charge of chlorine ion
n = number of chlorine ion = 
e = charge on electron = 
Now put all the given values in the above formula, we get:

Now we have to calculate the current passing between the electrodes.



Thus, the current passing between the electrodes is,
