We know that the current in the circuit is growing. it will approach a steady state after a long time (as t tends to infinity), which implies that the differential term in our circuit equation will tend to zero, hence simplifying our equation. the current around the circuit will tend to an asymptotic value iasymp. what is iasymp? express your answer in terms of vb and r and other constan

b.

hope this : )

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

the answer is b, have negligible mass

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
