Two long, charged, thin-walled, concentric cylinders have radii of 3.0 and 6.0 cm. The charge per unit length is 6.00 β 10β6 C/m on the inner shell and β7.50 β 10β6 C/m on the outer shell. (a) Find the magnitude and direction of the electric field at radial distance r = 4.7 cm from the common central axis. (Take radially outward to be positive.) N/C (b) Find the magnitude and direction of the electric field at r = 8.1 cm, using the same sign convention. N/C

The lid of a pressure cooker forms a nearly airtight seal. steam builds up pressure and increases temperature within the pressure cooker so that food cooks faster than it does in an ordinary pot. the system is defined as the pressure cooker and the water and steam within it. if 2.0 g of water is sealed in a pressure cooker and then vaporized by heating, and 5127 j must be added as heat to completely vaporize the water, what is the change in the systemβs internal energy? answer in units of j.
