The speed of a longitudinal wave would increase, as the kinetic energy molecules would move quicker in response to the higher temperature.
This is false/ i know because i live in an urban area and it increases by human construction.
Answer:
Explanation:
<u>Chemical formulas for every compound:</u>

The total number of protons and neutrons in an atom is called the mass number. You can find the mass numberfor any element. The mass number canbe found by rounding the average atomic mass to the nearest whole number.
as an example
6.25 is closer to 6 than 7 so it is 6
6. 50 is closer to 7 so it is 7
you have to look at the thenth digit. if the number is 4 or less you have to round it down
if the tenth digit is 5 or greather than you have to round it up.
Answer:
false
Explanation:
A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pH changes very little when a small amount of strong acid or base is added to it. A buffer protects from ph increasing.
