are composed of ionized gas trapped in a magnetic arch rising above the surface of the Sun. When seen along the edge of the Sun, they appear pink in color. However, when seen against the Sun's bright surface they appear as dark.

Phase changes are chemical changes. true or false

Acar moves at 12m/s and coasts up a hill with a uniform acceleration of -1.6m/s2. how far has it traveled after 6.0s?

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j
