A) find the moon’s angular size at its minimum and maximum distances from earth.

Two large, flat, horizontally oriented plates are parallel to each other, a distance d apart. half way betwween the two plates the electric field has magnitude e. if the separation of the plates is reduced to d/2 what is the magnitude of the electric field half way between the plates?

What will a positive and a negative charge do if they are separated from each other?

Give one example to show that when substances are mixed,it may result in a chemical or a physical change depending on the conditions.
