What effect can a very large volcanic eruption have on earth's climate
A it will warm the earths surface as more heat is trapped by the dust particles
B it will warm the earth's surface as more lava is released by the volcanic eruption
C it will cool the earth's surface as more snow will fall with the presence of more condensation nuclei
D it will cool the earth's surface as radiation from the sun is blocked from entering the atmosphere

Ajet plane has a sound level of 120 db at a distance of 60 m. what is the q23. sound level at a distance of 6.0 km? (60)2 (6000)? om solution 80db db, hint: 16x assume ultrasound waves travel through the body of an animal at 1540 q24. m/s. if a 30,000 hz signal were reflected off a portion of a heart which was moving toward the source at 3 m/s, what frequency signal would return to the stationary source? solution 30.117hz
