two resistors are to be combined to form an equivalent resistance of 1000 ohm. the resistance are taken from available stock on hand as acquired over the years. readily are two common resistors rated at 500+/_50 ohm and two common resistors rated at 2000 ohm+/_5%. what combination of resistors (series or parallel ) would provide the smaller uncertainity in an equivalent 1000 ohm resistance?

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

dang that balls went far

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
