Q1: Work done by a/an __________ process is determined by.

ANS:B - quasi-static

In physics and engineering, the term "quasi-static" refers to a process or system that changes very slowly with respect to the relevant time scales of interest. It is a simplifying assumption often used in the analysis of mechanical, thermal, or electromagnetic systems. In a quasi-static process, changes occur gradually, allowing the system to maintain equilibrium at each stage of the process. This means that the system remains very close to thermodynamic equilibrium throughout the process, and the forces and fields acting within the system can be assumed to be in balance at any given moment. Quasi-static processes are often easier to analyze mathematically because they allow for the application of equilibrium principles and simple mathematical relationships. They are commonly used in theoretical models, simulations, and engineering calculations to approximate the behavior of systems that undergo slow changes. It's important to note that the quasi-static assumption may not always be valid for rapidly changing or dynamic systems, where inertia, acceleration, or other time-dependent effects become significant. However, for many practical engineering problems, especially those involving mechanical systems moving slowly compared to characteristic time scales, the quasi-static assumption provides a useful and accurate approximation.
