What is the ratio of the intensities and amplitudes of an earthquake P wave passing through the Earth and detected at two points
gavmur [86]

For both cases we will use the proportional values of the distance referring to the amplitude and intensity. Theoretically we know that the intensity is inversely proportional to the square of the distance, while the amplitude is inversely proportional to the distance, therefore,

PART A )  Intensity is inversely proportional to the square of the distance

Intensity \propto \frac{1}{distance^2}

Therefore the intensity of the two values would be

\frac{I_{27}}{I_{13}} = \frac{(13km)^2}{(27km)^2}

\mathbf{\therefore \frac{I_{27}}{I_{13}} = 0.232 }

PART B) Amplitude is inversely proportional to the distance

Amplitude \propto \frac{1}{distance}

\frac{A_{27}}{A_{13}}= \frac{(13km)}{(27km)}

\mathbf{\therefore\frac{A_{27}}{A_{13}}= 0.4815}

11. You sit at the outer rim of a Ferris wheel that rotates 2 revolutions per minute (RPM). What would your rotational speed be
aalyn [17]
If you are instead clinging to a position halfway from the center to the outer rim of the Ferris wheel, YOUR ROTATIONAL SPEED WILL STILL BE 2 REVOLUTION PER MINUTE.
This is because, every part of the wheel is moving with the same speed, so it does not matter where you sit on the wheel, the rotation per minute will still be the same. It is just like travelling inside a motor car, it does not matter whether you are sitting in the front passenger seat or at the back, the speed of the car remains the same.
