During the formation of our solar system, the nebular dust began to cool and sections began to condense. Eventually, small grains stuck to one another via an electromagnetic force. As they grew, gravity helped to speed up the building process until planetesimals were formed. This process is called A) accretion.
B) expansion
C) orderly motion
D) angular momentum

What happens to an isotope during radioactive decay?

Since the energy was not raising the temperature of the water during these segments, what was the energy used to do instead? your answer must include an explanation of what is happening to the molecules.

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
