A sanitary landfill project needs an import soil for use as an impervious cap over the refuse. The following soils are available for this purpose: Soil 1: GC Soil 2: SC Soil 3: ML Soil 4: CLThe design engineer desires a soil with a high clay content because it will help keep water out of the landfill. Which of the available soils appears to be most promising? Why?

What is the normality of a sodium hydroxide solution that contains 250 mg/L NaOH in 2.3 L solution? What is the concentration in mole/L and mg/L as CaCO3. Na = 23, OH = 17
Let E be an unsorted set of n segments that are the edges of a convex polygon. Describe an O(nlogn) algorithm that computes from E a list containing all vertices of the polygon, sorted in clockwise order.
The acceleration of a particle along a straight line is defined by a=(2t-9)m/s^2, where t is in seconds.At t=0, s=1m, and v=10 m/s. When t=9s, determine the particles position, the total distance traveled, and the velocity.
