Answer:
Amperes WB =<em> </em>![200J](https://tex.z-dn.net/?f=200J)
Explanation:
Amperes will flow back to the negative terminal because both the positive terminal and negative terminal contain the equivalent amount of current that will flow and it works in the starter motor.

Answer:
The settlement that is expected is 1.043 meters.
Explanation:
Since the pre-consolidation stress of the layer is equal to the effective stress hence we conclude that the soil is normally consolidated soil
The settlement due to increase in the effective stress of a normally consolidated soil mass is given by the formula
![\Delta H=\frac{H_oC_c}{1+e_o}log(\frac{\bar{\sigma_o}+\Delta \bar{\sigma }}{\bar{\sigma_o}})](https://tex.z-dn.net/?f=%5CDelta%20H%3D%5Cfrac%7BH_oC_c%7D%7B1%2Be_o%7Dlog%28%5Cfrac%7B%5Cbar%7B%5Csigma_o%7D%2B%5CDelta%20%5Cbar%7B%5Csigma%20%7D%7D%7B%5Cbar%7B%5Csigma_o%7D%7D%29)
where
'H' is the initial depth of the layer
is the Compression index
is the inital void ratio
is the initial effective stress at the depth
is the change in the effective stress at the given depth
Applying the given values we get
![\Delta H=\frac{8\times 0.3}{1+0.87}log(\frac{154+28}{154})=1.04](https://tex.z-dn.net/?f=%5CDelta%20H%3D%5Cfrac%7B8%5Ctimes%200.3%7D%7B1%2B0.87%7Dlog%28%5Cfrac%7B154%2B28%7D%7B154%7D%29%3D1.04)
