There are the rise and fall of the sea level because of the gravitational force exerted by the sun, moon and the rotation of the earth.
Tidal force effect the whole earth, the movement of the earth by mere meter, change in atmosphere as it mostly consists of fluid the movement of fluid takes place in kilometers.
Hence, we can say that tidal bulges have a wavelength in order of thousands of kilometers.
The correct answer is option E
Answer:
2.45 g/mL
Explanation:
(assuming that the original volume was 20 mL and not L)
Since you know the amount of water in the cylinder before and after you placed the rock in, you can subtract them to get the volume of the rock itself. 
mL.
To get the rock's density, use the equation 
, where m is mass and v is volume.
