Salwa is a researcher at the University of California, Berkley. She wants to develop an irrigation system for crops that could also provide hydroelectric power for farms to produce their own energy in an entirely sustainable way. She has a like-minded team of researchers to help her develop her project, but she needs research funding. To focus her funding efforts, she wants to select no more than three potential sources that would be best positioned to meet her needs. Where should she turn for project funding? (Select all that apply.) A. state funding
B. private sector funding
C. university funding
D. National Science Foundation (NSF) funding

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?
