Auniform linear charge density a is placed on an infinitely long wire. the wire is parallel to an infinite grounded plane, and a distance b above that plane. to make things specific, the points on the wire are described as (x, 0, b), and the conducting plane is z 0. a. find the potential v(o, y, z) for z> 0. b. find the induced charge density ơ(x, y) on the conducting plane

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.

Heating water for hot cocoa while sitting next to a campfire can be examples of conduction, convenction and radiation at the same time agree disagree it depends how you know

Auniform electric field exists in the region between two oppositely charged plane parallel plates separated by a distance of 1.60 cm . a proton is released from rest at the surface of the positively charged plate and strikes the surface of the opposite plate in a time interval of 3.20×10-6 s. 1-find the magnitude of the electric field. use 1.60×10-19c for the magnitude of the charge on an electron and 1.67×10-27kg for the mass of a proton 2-find the speed of the proton when it strikes the negatively charged plate
