The answer is C. Subduction.
The answer is
Longitudinal waves.
The particle displacement in a longitudinal wave is
parallel to the direction of wave propagation. The ground particles simply oscillate
back and forth their equilibrium positions unlike transverse waves that do not
move along with the waves but rather oscillate up and down their individual
equilibrium positions.
For consumers in the United States I think........... what are your choices?
So a 1st magnitude star is 2.512 times brighter than a 2nd magnitude star, and 2.5122=6.31 times brighter than a 3rd magnitude star so your answer would be a second-magnitude star is brighter than a third-magnitude star
