314. ## To Ms. Sue

Ms. Sue could you please read my essay and tell me if it's good? I don't have time to rewrite it, would just like to know your opinion about it.

315. ## physics

charging by induction creates charge by transferring charges from one object to another OR separates charges within an object

316. ## aims math<<<<need some one to check my answer

okay this problem is simple... well my answer im unsure the answers i get arent an option. the problem is: 37-3[5+4(3-7)]

317. ## physics

while many properties are similar, one important difference between electric and gravitational forces is that unlike gravity, electric charge: a)can be transferred b) objeys an inverse-square law
