Which of the following is an example of a scientific law?1.Experimental results that show that v = λf2.An explanation for why some electrons are affected when they are hit by photons and some electrons are not.3.A prediction that increasing the volume of an object will increase its ability to float in water4.None of the above

Answer 1

In general, a scientific law describes a phenomenon (or what phenomena will happen given specific circumstances) without explanations of the reasons. On the other hand, scientific theory aims to explain the reasons as to why phenomena occur.

Given this information, the most appropriate answer choice is:

3. A prediction that increasing the volume of an object will increase its ability to float in water
