Aplastic rod that has been charged to -15.0nc touches a metal sphere. afterward, the rod's charge is -10.0nc. part apart complete what kind of charged particle was transferred between the rod and the sphere? what kind of charged particle was transferred between the rod and the sphere? electrons protons previous answers correct

Negatively charged particles (electrons)

Explanation:

Plastic rod is charged -15.0 nC. It is clear that the charge on the rod is negative so the rod has gain excess of electrons.

When the rod touches a metal sphere charge on the plastic rod remains -10 nC, i.e. negative charge on the rod decreases. This is because negatively charged particles (electrons) are transferred from the plastic rod to the metal sphere.

whichever one it is, it's definitely not one that you included on the list you provided.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
