How do warm ocean currents affect the weather? They make the equator warmer.
They make the tropical regions warmer.
They reduce precipitation in coastal areas.
They result in warmer air temperatures near the current.

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
