Suppose a uniform electric field of 4 N/C is in the positive x direction. When a charge is placed at and fixed to the origin, the resulting electric field on the x axis at x = 2 m becomes zero. What is the magnitude of the electric field at x = 4 m on the x axis at this time?
A. 0 B. 1 N/C C. 2 N/C D. 4 N/C E. More information is needed to find the resulting field magnitude at this position.
As the average surface temperature of the Earth rises, the Northern hemisphere of the Earth is warming more rapidly than the Southern hemisphere because
A) the Northern hemisphere contains more landmass which more readily absorbs solar radiation B) during summer in the Northern hemisphere, the Earth is closer to the Sun C) there is less ice in Arctic regions compared to the Antarctic regions so less radiation is reflected out into space D) there are more clouds in the Southern hemisphere to reflect solar radiation out into space
