se aplica una fuerza de 35 N sobre una superficie de 2.2 m2 .Calcula la presion que esta ejerciendo dicha fuerza​

i think the answer is a, hope this : )

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
