When you push down on a block resting on a table, block atoms and table atoms that are in contact with one another
what is your question?
sorry. When you push down on a block resting on a table, block atoms and table atoms that are in contact with one another A. maintain their positions B. break their bonds with one another C. move closer to one another D. move past each other
it depends on your force if you push decently then they maintain there position if you push hardly then atoms come close if you push them using a powerful machine then there bonds can also broken
assume that it would be an average person
move past each other, i believe there is no bonding else it would be tough to break them apart, actually there is interlocking between surfaces of two objects so it's D
what about other options?
|dw:1348662439798:dw| i have shown two surfaces, they are not perfectly plane so they interlock each other and that's the reason of friction
and when the applied force overcomes this frictional force body starts moving
The answer that the graded quiz gives is C
see when the force is not enough to overcome friction it will be stable and surface will come closer so according to this explanation it's C but if magnitude of force is large with proper direction it will make the object move
