If you think about it, irregular galaxies dont really have a describable shape, as you can tell by the name. So B.
Choice 'b' is one possible way to state
Newton's second law of motion.
The other choices are meaningless.
Potential energy increases as speed decreases. Kinetic increases when speed increases.
Answer:
The net torque is zero
Explanation:
Let's assume that the dipole is compose of two equal but oposite charges e, and it cam be represented by a rod with one end having a charge e and the other end with a charge of -e. Notice that the dipole is parallel to the electric field thus the force felt by both of the charges will be parallel to the electric field. This means that there will be no components of the forces that are perpendicular to the rod which is a requirement for it to have a torque.
