"The potential on the surface of a conductor is always zero."
This statement is false. A good number of times we define a point's potential to be the amount of work that must be done to move 1 coulomb of charge from infinitely far away to that point. So if, let's say, the conductor had a net positive charge, then you would need to do a net positive amount of work to move 1 coulomb of charge from infinitely far away to any point on the conductor's surface. We have just provided a case for which the potential on the surface of the conductor is not 0.
Hey there,
It is C, Platelets
There are 4 types of macromolecules. They are Carbohydrates, Lipids, Proteins and Nucleic Acids.
Hope this helps :))

Answer:
When the object is moving in a straight line distance will be equal to displacement. ... Shortest path = Actual path,because object travelled in a straight line. Displacement and Distance should have same magnitude because the object has not changed its direction.

Answer:
One explanation may be that as a group, teenagers react more impulsively to threatening situations than do children or adults, likely because their brains have to work harder to rein in their behavior, a research team reported here yesterday at the Society for Neuroscience meeting
