Wet haze can form when the relative humidity is as low as percent

The correct answer is - 75-80%.

The haze is a hazardous occurrence. It is a slight obscuration of the lower atmosphere, and the cause for its occurrence are the fine suspended particles. Thus we can conclude that the haze is actually caused by pollution of the air.

While the haze typically is a dry air phenomenon, it can also be a wet one if the conditions are right, though that happens relatively rarely. If the humidity in the air is 75-80% than the tiny aerosol particles of the dry haze start to act as condensation nuclei, resulting in a wet haze.

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5
