Acertain type of rechargeable battery is capable of delivering a current of 0.2 a for 4000 s, before its voltage drops and it needs to be charged. calculate:

1) the total charge the battery can deliver before it needs to be recharged,

2) the maximum time it could be used for without being recharged if the current through it were 0.5 a

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

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
