The graph below shows the potential energy as a function of internuclear distance for molecular bromine, Br-Br and an unknown heteronuclear diatomic
molecule, A-B. Based on the data in the graph, which of the following correctly
identifies the diatomic molecule A-B?

h let me think

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
