Two bar magnets are labeled a and b. the ends of each magnet are numbered 1 or 2, but the poles are not labeled. when a1 is brought near b1, the bars repel. which conclusion is best supported by the data? a) a1 is the north pole of a magnet, and b1 is the south pole of a magnet. b) a1 is the north pole of a magnet, and b1 is the north pole of a magnet. c) a1 and b1 are opposite poles, but there is not enough information to tell which ones. d) a1 and b1 are like poles, but there is not enough information to tell whether they are north poles or south poles.

D) A1 and B1 are like poles, but there is not enough information to tell whether they are north poles or south poles.

Explanation:

When A1 is brought near B1 the bars will repel each other

As we know by the properties of magnet that when two bars are of similar nature then they will repel each other

so here A1 and B1 are of same type

so correct option must be

D) A1 and B1 are like poles, but there is not enough information to tell whether they are north poles or south poles.

explanation:

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
