Acceleration because it is at a rise in speed. The formula for acceleration is Speed/Time.

Oxygen has an atomic number 8, because it has 8 protons and 8 electrons.
The first shell of an atom can hold up to 2 electrons but oxygen has 8 electrons, in that eight electrons 2 are in the first shell, so it has 6 more electrons left. The second shell can hold up to 8 electrons, oxygen has only 6 more electrons after the first shell is full, so it will have 6 electrons in the second shell
From this we know that oxygen has 2 shells so it is in period 2, and by counting from left to right, the sixth box in period 2 lies on group 16
Therefore Oxygen lies on group 16 and period 2

Answer:
74dB
Explanation:
Sound intensity is inversely proportional to the square of the distance. Thus, a house four times closer hears a sound 16x more intense.
The dB scale is logarithmic, so 16x louder than 62 dB is equal to
62 + 10*log(16) ~= 62 + 12 = 74dB
