Answer:

because volcanoes in the center of the ridge push the pre-existing seafloor on either side of it away from it at equal speeds

also when the earth's polarity flips, the crystals on either side of the spreading center are affected equally, so the bands are always the same distance from the ocean ridge

also because when the magma solidifies (which is what "freezes in" the magnetic orientation), the magnetic field of the earth exerts the same force on both sides of the ridge (the midline of the spreading).

itan's orbital radius is about 1222000 km and its orbital period is just under 16 days. From this information, estimate the mass

maksim [4K]

Answer:

$5.67\cdot 10^{26} kg$

Explanation:

For a satellite in orbit around a planet, the gravitational force between the planet and the satellite is equal to the centripetal force that keeps the satellite in circular motion.

So, we can write:

$\frac{GMm}{r^2}=m\frac{v^2}{r}$

where

G is the gravitational constant

M is the mass of the planet

m is the mass of the satellite

r is the orbital radius of the satellite

v is the speed of the satellite

The equation can be rewritten as

$M=\frac{v^2r}{G}$

Also, we can write the orbital speed as the ratio between the length of the orbit (circumference of the orbit) and orbital period, T:

$v=\frac{2\pi r}{T}$

Substituting into the equation for M,

$M=\frac{4\pi^2 r^3}{GT^2}$

Here we have:

$r=1,222,000 km = 1.222\cdot 10^6 km = 1.222\cdot 10^9 m$ is the orbital radius

$T=16 d \cdot 86400 s/d=1.38\cdot 10^6 s$ is the orbital period

Substituting, we find the mass of the Saturn:

$M=\frac{4\pi^2 (1.222\cdot 10^9)^3}{(6.67\cdot 10^{-11})(1.38\cdot 10^6)^2}=5.67\cdot 10^{26} kg$

If you were a hydrologist and you happen to take charge of the in

Stels [109]

We can actually infer here that as a hydrologist who happen to be in charge of the inspection of the Laguna de Bay and Manila Bay, the water distribution on these areas in terms of freshwater and salt-water can be quantified according to their degree of salinity. Laguna de Bay is a fresh water lake whose degree of salinity is lower than that of the Manila Bay.

<h3>What is Laguna de Bay?</h3>

The Laguna de Bay is actually known as the third largest inland body of water. It is located in Southeast Asia. It is found in the heart of Luzon Island.

The Manila Bay is known as the natural harbor which is known to serve the Port of Manila (on Luzon). It is located in the Philippines; the capital city of the Philippines.
