Certain brand of hotdog cooker works by applying a potential difference of 130 v across opposite ends of a hot dog and allowing it to cook by means of the thermal energy produced. the current is 12.6 a, and the energy required to cook one hot dog is 62.5 kj. if the rate at which energy is supplied is unchanged, how long will it take to cook three hot dogs simultaneously?

Explain using examples, what is simple harmonic motion and why it is an important area of study in physics.

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

Acup of coffee sits on the dashboard of an automobile. the car goes around a sharp curve. even though you hold the cup still, coffee still splashes out. this can best be explained due to a) density. b) friction. c) gravity. d) inertia.
