Describe current in terms of charge and electrons.

PLEASE HELP I WILL GIVE BRAINLIEST

Rank the torques on the five doors shown in the figure above from least to greatest. note that the magnitude of all the forces is the same

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.

Heterogeneous mixture with larger particles that never settle is
