Answer:
3. 3.5 s
Explanation:
The position of traveller A is given by the equation:
where
is the acceleration of A
t is the time measured from when A started the motion
The position of traveller B instead is given by
where a (acceleration) is the same as traveller A, and
is B's initial velocity. We can verify that the formula is correct by substituting t=2, and we get 
, which means that B starts its motion 2 seconds later.
Traveller B overtakes traveller A when the two positions are the same, so:
Answer:
the free encyclopedia. In molecular geometry, bond length or bond distance is defined as the average distance between nuclei of two bonded atoms in a molecule. It is a transferable property of a bond between atoms of fixed types, relatively independent of the rest of the molecule.
Explanation:
Answer:
B
Explanation:
Depends Mostly on bonds electrolysis can be used, chemical bonding like additional of water or by heating back to their elements.
The answer is most likely A
