Auniform steel plate has an area of 0.923 m2. when subjected to a temperature difference between its sides, a heat current* of 23100 w is found to flow through it. what is the temperature gradient? what is the temperature difference when the plate is 0.0493 m thick? the thermal conductivity of steel is 50.2 w/(m·k).

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
