Aproton accelerates from rest in a uniform electric field of 700 n/c. at one later moment, its speed is 1.10 mm/s (nonrelativistic because v is much less than the speed of light). (a) find the acceleration of the proton. m/s^2 (b) over what time interval does the proton reach this s (c) how far does it move in this time m (d) what is its kinetic energy at the end of this j

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.

Dao makes a table to identify the variables used in the equations for centripetal acceleration. what quantities belong in cells x and y?
