Mechanical Energy At what point on the rollercoaster is
the kinetic energy the highest?
A. point A
B. point B
C. point C
D. cannot be determined
with the information provided.

Point C

Explanation:

Remember that kinetic energy is energy a object has when it's in motion so the higher the speed, the higher the kinetic energy is. In this case we have a roller coaster, as the roller coaster goes up the tracks it's kinetic energy is low because it slows down as it climbs to the top of the hill. Then as it sits on top of the hill it's kinetic energy is little to none before it goes down the hill because the roller coaster isn't in motion. As when the roller coaster goes down the hill it's speed increases meaning the kinetic energy increases which means option C or "point C" is your answer.

Hope this helps.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
