An object, undergoing simple harmonic motion with an amplitude of 0.20 m, takes 0.50 s to travel from one point of zero velocity to the next point of zero velocity. what is the period of oscillation of the object

Why cooking gas has a typical smell

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
