define Enthalpy - answer-total energy of a system Which of the following is true of the electric field intensity about an isolated point charge? A. It varies directly as the distance to the charge. B. It varies inversely as the distance to the charge. C. It varies directly as the square of the distance to the charge. D. It varies inversely as the square of the distance to the charge. - answer-D. It varies inversely as the square of the distance to the charge. As a professional engin...

What kind of test is depicted by a stress-strain diagram? - answer-tensile test What term is used for the ratio of stress to strain below the proportional limit? - answer-Young's modulus What does the impact test measure? - answer-toughness What is true regarding the ductile-to-brittle transition temperature? - answer-It is important for structures used in cold environments; It is the temperature at which 20 J of energy causes failure in a Charpy V-notch specimen of standard dimensions...

Aquifer - answer-underground geologic unit that is saturated with water which contains sufficient permeability to yield the water to wells. Unconfined aquifer - answer-Water surface is at atmospheric pressures. Confined aquifer - answer-Aquifer that is confined by an impermeable material, such as clay or shale, resulting in the aquifer being under pressure. Permeability - answer-A measure of the ability to transmit fluids based on the material within the aquifer. Transmissivity - ans...
