The resulant/net force two forces p and q is 7 n which of the following is the maginitude of force q if force p is equal to 3n? a. 2n b. 3n c. 8n d 13n

Think of this as a triangle. There is no way you could make p and q fit together if one of them is 2 or 3 and the other is given as 3. The most those two would be 6 which is less than 7. 

8 would work. You'd get a triangle where 3 went up and 7 was horizontal. You could make 8 work. 

13 is too big. Your answer must be less than 10

This is a tricky question. Thanks for posting.

Honestly "global warming" may be a slight possiblity, however they called it "climate change" because its not real, in fact we had one of our coldest days here not too long ago, and the "issues" with this subject is a blindfold for actual problems.
