Question

Q: Which of the following are manifestations of solar magnetic activity?

sunspots
flares

prominences

all of the above

Q: How did the system of planets orbiting the Sun form?

he planets formed from the same materials as the Sun, assembled to current organization by gravity and angular momentum.

The planets and the Sun formed at the time of the Big Bang. The planets were captured by the Sun’s gravity.
The planets formed from the fusion of hydrogen in their cores.

Q: (T/F) ?? The Sun is in hydrostatic equilibrium, which points to a perfect balance between the force of gravity that pulls the star in, and the expanding gas- pressure force that attempts to expand the star outward.

Q: The solar neutrino problem was solved by:

improving detector efficiencies so more neutrinos were observed.

postulating that neutrinos had mass and oscillated between three different types.

lowering the percentage of helium in models of solar composition. adjusting the rates of hydrogen burning in solar models

Answer 1

1 all the above

2 second option, formed from hig bang and pulled by gravity of earth

3 true

4 option 2 that the neutrinos exist in different states
