Explanation:

a.) Dry unit weight b.) Void ratio c.) Porosity d.) Degree of saturation Solution: a) γd= γ1+?= 17.611.108= 15.89 kN/m3b) γd= γ? ?1+15.89 = (2.67)(9.81)1+e = 0.65 c) n = e1+= 0.651.65= 0.39 d) Se = wGsS = (0.108)(2.67)0.65x 100% = 44.50% 3.2Refer to Problem 3.1. Determine the weight of water, in KN, to be added per cubic meter of soil for: a.) 80% DEGREE OF SATURATION b.) 100% DEGREE OF SATURATION Solution: a. ) S = v? ??∆S = 80 –44.50 = 35.5% n = v? ?; VT = 1m3 0.39 = v? 1Vv = 0.39 0.355 = v? 0.39; Vw = (0.355)(0.39) Vw = 0.140 m3 Ww = 0.140 x 9.81 = 1.37 Kn

What would have happened if the angle between the orbital planes of the earth and the moon remains 0°
UkoKoshka [18]

Answer: The Moon's orbit about the Earth lies in a plane which is tilted by about 5.15° with respect to the plane of the Earth's orbit about the Sun. (If this tilt was zero, we would have total solar and lunar eclipses every month!) ... For example, the Moon travels faster across the sky at perigee, and slower at apogee.
