Using the loop rule and deriving the differential equation for an lc circuit find the current (sign included) through the inductor at the instant t = 1.0 s if l = 3.4 h, c = 3.3 f . the initial charge at the capacitor is q0 = 4.2 c and the initial current through the inductor is i0 = 0.

The mentor is usually a peer of the individual that acts as a role model and the individual get started in adult life.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Does work output exceed work input when a machine is used? a) yes, it does, as machines create energy. b) it depends on the type of machine used. c) no, it doesn’t, as machines are inefficient. d) no, it doesn’t, as machines cannot create energy.
