explain fully what is a satellite image and how it is taken
​

a satelite image helps researchers collect information on many things like how the atmosphere in the earth is changing and  shows what the land and terrain looks like. its also an accurate way to create maps.

they are taken by the cameras on satelites or certain aircrafts.

a is the answer i believe.

because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. so, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.
