The only information you would need to decide if the can will float is the density of the can, which requires knowing the mass and volume. If the density of the can is less than one, the can will float. if it is greater than one, it will not float, as water's density is one.
Answer:
The correct answer is - do nothing.
Explanation:
If two same or identical objects, in this instance two glass rods, were rubbed together they neither attract nor repel each other as there is no transfer of electrons from one material to the other material as there is no difference in their charges.
Only two different objects are able to transfer electrons from one material to the other material if rubbed together, to produce the conditions for static electricity to be observed. Therefore there would be no charge on the glass rod so there would be no charge to balls to repel or attract.
Electric field lines of positive charges are always radially outwards
So here all field lines must have tendency to move out radially as well as two field lines never intersects with each other
So here field lines also do not intersects with each other
So overall the figure C is perfectly representing the field lines of two positive charges as these lines are not intersecting and also originating from two positive charges.
So answer must be
<u><em>FIGURE C</em></u>
Answer:
Explanation:
As the potential energy of the freely falling object decreases, its kinetic energy increases on account of an increase in its velocity. ... Thus, the law of conservation of energy is not violated.
