In the experiment, you will determine whether adding nutrients to the soil changes the community of plants
growing there. This is done by looking at the habitat's
composition and structure. Write a scientific question that
you are answering by doing this lab. Write your question
in general terms, not in terms of specific plants.

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
