Answer:
hope this helped
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
B is your answer because there was very little wood in the area
From oldest to youngest: I, B, F, M, R, H.
Explanation:
On the picture we can see several layers of rock. Some of the layers have not been disturbed, so the principle of superposition can be applied to them. Some of the layer though have been disturbed by geological processes, so the layers are not at the same level because of it. On top of it, there is also an intrusion that has managed to further cause disturbance through all of the layers.
- The layer I is the oldest, and it is the basis of the others.
- Layer B has formed next, and after that layer F.
- These three layers have been influenced by the formation of fault, where one of their sides has been moving up relative to the other, while the other has been moving down relative to the other.
- Layer M is younger layer, and it can easily be seen as it totally covers the layer F below it.
- On top is layer R, which is the youngest of them all (the layers), and the one that comes out on the surface.
- Layer H is not really a layer, but it is an intrusion, which has formed after magma managed to cut through all the layers and later solidify. It is the youngest formation.
