You and a friend are spending the weekend making up missed lab experiments. you are on to second - semester material and are studying the electrostatic interaction of two charges. you notice that two charges are exerting a certain force on one another. if the distance between two electric charges doubles, then the force they exert on each other changes by how much?
2 times as large
4 times as large
1/4 as large
1/2 as large

Positive ions differ from neutral atoms in that

How is the acceleration of an object in uniform circular motion constant? a - in magnitude only b - in direction only c - in both magnitude and direction d - in magnitude, direction & orientation

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
