Earthquakes produce P and S waves. The P waves are fast and of a higher frequency than S waves. P waves reach a point first and can pass through liquid media while S waves reach after and the lose much of their energy while passing liquid media. This is because S-waves are shear waves and require rigid/inelastic media for transmission.
During an earthquake, there is usually a shadow zone (where there is no destruction because S-waves did not reach) formed right above the epicenter of the earthquake. This is due to the fact that the S-waves were unable to transit through the liquid inner core of the earth before reaching the earth's surface. Only P-waves are registered in this shadow zone.
Answer:
1. 
2. The equation to calculate Density is Mass / Volume. You are given that the density is 5.45 and the mass is 65; 5.45 = 65 / v. So v = 65 / 5.45; v = 11.93 mL (or if you want your answer to consider significant figures, v = 12 mL).
3.
m = 43.5 g
V = 50 mL
d = 43.5 g / 50 mL = 0.87 g/mL
Density of this cooking oil is 0.87 g/mL.

About a month
Explanation:
It takes 27 days, 7 hours, and 43 minutes for our Moon to complete one full orbit around Earth. The lunar cycle is measured by our Moon's position relative to distant “fixed” stars
