In an automobile, a 12 volt battery simultaneously supplies electrical energy for the ignition, lights and radio. this electrical circuit must be a) ac in series. b) dc in series. c) ac in parallel. d) dc in parallel.

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c

Give an example in which the electrical energy changes to light energy

Photons with the highest energy have the longest period
