A flexible spring is lying on the floor. You grasp one end with your hand and move your hand to the left and right (parallel to the floor) over and over again. The far end of the spring can be seen also moving left and right. What type of wave have you created?

How will the system respond to a temperature increase?

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

An element becomes a positively charged ion when itloses protons.loses electrons.gains electrons.gains neutrons.
