a conducting rod moves perpendicularly through a uniform magnetic field. how does the emf change if both the velocity of the rod and the length of the rod are doubled?

Which statement is true for light passing into a medium that is more optically dense than the first medium through which it past

State the right hand rule of the direction of magnetic field in a conductor carrying current

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
