An aluminum rod with a gauge length of 1.18 m undergoes thermal expansion from 20 oC to 92 oC. The thermal expansion coefficient and elastic modulus of aluminum are 22.2 * 10-6 K - 1 and 68.9 GPa respectively

What is a good reason to keep a project's file size small? A. The file will take longer to export. B. The objects in your project will be organized better. C. It takes less time to send the file in an e-mail message. D.

Indicate whether the following statements are true or false for a reversible process: (A) Q=0. (B) Work may be calculated using the equation of state. (C) The entropy change of the system is zero.

Any one here play animal crossing new horizons if so wanna play

without using the routh hurwitz criterion, determing if the followign systems are asymptotically stable, marginally stable, or unstable. In each case, the closed-loop system transfer function is givenMs = [10 (s+2) ] / (s^3 + 3s^2 + 5s)

What is operant conditioning

Just getting to your class is enough for showing up. A) True B) False

A completely reversible heat pump produces heat at a rate of 100 kW to warm a house maintained at 25℃. The exterior air, which is at 0℃, serves as the source.

A closed system undergoes a process in which work is done on the system and the heat transfer Q occurs only at temperature Tb. For each case, determine whether the entropy change of the system is positive, negative, zero, or indeterminate.
