sphere change?
It has an excess of positive charge.
It has an excess of negative charge.

It has a positive charge inside of the sphere.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

that tool would be a compass

the correct answer would be d. hope this !

idk what is it? is this a question that you know the answer or u dont
