Which statement best describes what used to be called the solar neutrino problem?
A) Theoretical models predict that neutrinos should be produced in the Sun, but no neutrinos had ever been observed to be coming from the Sun.
B) Solar neutrinos were detected in fewer numbers than predicted by theoretical models.
C) Theoretical models did not predict the production of neutrinos by the Sun, yet solar neutrinos were detected.
D) Theoretical models predicted that all solar neutrinos should be destroyed before they arrive at Earth, yet neutrinos were detected on Earth.
E) The neutrinos that were being detected from the Sun had much smaller masses than theoretical models could account for.
B) Solar neutrinos were detected in fewer numbers than predicted by theoretical models.

A long solenoid with closely spaced turns carries electric current. Each turn of wire exerts:
1.an attractive force on the next adjacent turn. 2.a repulsive force on the next adjacent turn. 3.zero force on the next adjacent turn. 4.either an attractive or a repulsive force on the next turn, depending on the direction of current in the solenoid.
Current that is typically 60 hertz is
A) direct current. B) alternating current. C) either of these D) neither of these
