For the following scenarios tell whether you think a refraction survey or a reflection survey would give better results and explain why. Also state how you think the geophone strands and seismic source should be set up (examples: refraction survey with shots at either end or both ends, or a reflection survey with a shot in the center)
1) You have been hired to do a survey to search for old tunnels that are rumored to be in the area, previously used to smuggle people across the US-Mexico border. The tunnels are not expected to be exceptionally deep underground.
2) You are doing a survey to contour the water table across a 2 mile stretch of land between a river and a farmer's field. He wont let observation wells be drilled in his field, but the water table data needs to be gathered.
3) A basalt flood plain covers what archaeologists believe to be the ruins of a stone castle and its surrounding farmland. When a rift erupted approximately 500 years ago the basalt flows covered the already demolished castle. The basalt layer is thick enough that it could conceal rubble from stone walls and foundations and would not be easy to dig through or see through with ground penetrating radar. Also, Do you think a seismic survey could locate the buried castle ruins in the middle of the buried farmland?
For each of the following transitions, draw E2,y2 on the specific energy chart and fully describe the reasoning. a. In a rectangular channel, there is a sudden drop in the channel bottom. Did the water depth increase or decrease
A two stage rocket with a total mass of 925kg is traveling at a speed of 6.6 10^3 m/s away from the earth . A predesigned explosion separates into two sections of equal mass that move with a speed of 2800m/s relative to each other along the original ..
A light bar AD is suspended from cableS and supports a 20 kg block at C. The extremities A and D of the bar are in contact with frictionless, vertical walls. Determine the tension in cable BE and the reactions A and D

The maximum specific growth rate of the organisms driving this reaction is 5.0 days -1 and the growth rate is 0.54 day-1. The activated sludge tank has a volume of 40 m3 and the flow rate into it is 400 m3/day.
What are minerals and sketch different types of mineral crystal forms and list different types of rock forming minerals. Describe with examples the importance of mineral identification in engineering applications.
An air-water vapor mixture at 0.1 MPa, 35 C and 70% relative humidity occupies a volume of 100 m^3 Determine the humidity ratio, the dew point, the mass of dry air in the volume and the mass of water vapor in the volume.
Determine the height, h, the water level will rise in the tank before remaining constant. Also, if initially the tank is empty, what amount of time will it take for the water level to rise to h? Be sure to justify all assumptions made.
Water occupies the bottom 0.8 m of a cylindrical tank.On top of the water is 0.3 m of kerosene, which is open to the atmosphere. If the temperature is 20 degrees C, what is the gage pressureat the bottom of the tank
For the free-falling patachutist with linear drag, assume a firstjumper is 70 kg and has a drag coefficient of of 12 kg/s. If a second jumper has a dragcoefficient of 15 kg/s and a mass of 75 kg, how long will it take him to reach the same velocity t..
A total of 13,610 kg/h of air at 1 atm abs pressure and 15.6C is to be heated by passing over a bank of tubes in which steam at 100C is condensing. The tubes are 12.7mm OD, 0.61 m long, and arranged in-line in a square pattern with Sp=Sn= 19.05mm.
