Answer:
B. A student asking others to join the leadership club.
Explanation:
A parent isn't a peer, therefore can't be peer pressure. Drinking is negative for your body, therefore not positive peer pressure. A teacher isn't a peer, therefore the only answer left is B.
His average speed is (35m/45s) = 7/9 meters per second.
His average velocity is (30m W + 5m E) / (45s) = 25 m/s West .
Most likely the answer is B.
Answer:
The lowest energy of electron is the ground state.
Explanation:
Answer:
sodium and chlorine have a large difference in electronegativity (the ability of an element to pull on electrons), resulting in a big difference in electron sharing, producing a molecule with a large “dipole moment” or polarity. The polarity means that the components (ions, in this case) are REALLY attracted to each other, and are so attracted that they stick together (in this case, in a crystal lattice). It takes a LOT of energy to get them to loosen this lattice and melt. All that energy = high temperature.
hydrogen and chlorine don’t have such a large difference in electronegativity, therefore
not as much polarity
the parts aren’t as attracted to each other
takes less energy to melt the solid
