An electric field of 3x10^16 n/c is needed to create a spark in the air. if the charged particles in the field are separated by a distance of 1mm how many coulombs of charge are needed for a spark (round to the nearest whole number)

option number c is the right answer.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
