A protocol for desalting oligonucleotide solutions specifies centrifugation of a 1,250 uL aliquot of solution at 3300 X g for 30 min. The rotor in your centrifuge has a maximum radius of 4.8 cm. What rpm should you use to centrifuge the solutions? Answer to the nearest whole number.

double the distance = divide strength by 4

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.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
