Which of the following best summarizes the quantum model of atoms? a. electrons reside in known positions in fixed orbits around the nucleus. b. electrons are waves that travel in known paths around the protons. c. electrons display some properties of waves and while they reside outside of the nucleus, their positions cannot be known with certainty.

The energy produced as a result of this flow of electrons from atom to atom is called

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)

How do i solve this physics problem?
