1) The pressure head is 3 m at point in a glacial till that is 2 meters below ground level. The bulk density of the till is 2000 kg/m3. What is the effective stress at this point? Express your answer in kPa to 2 significant figures (numeric answer only)

2) What pressure head will result in "quick conditions" at a point 2 meters below ground level (bulk density is 2000 kg/m^3). Recall that quick conditions occur when effective stress is equal to 0 kPa. Express your answer in meters to 1 significant figure (numeric answer only)
