Kaylis [27]

Answer:

Depth of the pool, h = 4.004 cm

Explanation:

Pressure at the bottom, P = 39240 N/m²

The density of water, d = 1000 kg/m³

The pressure at the bottom is given by :

P = dgh

We need to find the depth of pool. Let h is the depth of the pool. So,

h=\dfrac{P}{dg}

h=\dfrac{39240\ N/m^2}{1000\ kg/m^3\times 9.8\ m/s^2}

h = 4.004 m

So, the pool is 4.004 meters pool. Hence, this is the required solution.

In Ptolemy's Earth-centered model for the solar system, Venus's phase is never full as viewed from Earth because it always lies
tiny-mole [99]
<h2>Answer: in full phase</h2>

Explanation:

Galileo observed that Venus presented phases (such as those of the moon) together with a variation in size; observations that are only compatible with the fact that <u>Venus rotates around the Sun and not around Earth.  </u>

This is because Venus presented <u>its smaller size when it was in full phase and the largest size when it was in the new one</u>, when it is between the Sun and the Earth.  

In other words: When Venus is in its full phase it is not possible to observe it from the Earth because always in this phase, Venus, the Sun and the Earth are in conjunction (or aligned).  This means <u>the Sun is between Venus and Earth</u>, in the orbit that both planets describe around this star.

Therefore, from the Earth, the Sun covers Venus.

This fact along with other discoveries were presented by Galileo to the Catholic Church (which supported the geocentric theory at that time) as a proof that completely refuted Ptolemy's geocentric system and affirmed Copernicus' heliocentric theory.

Name each planet in the solar system
satela [25.4K]
Mercury is the closest planet to the sun.

Venus is second planet. Venus has no moons.

Earth is the third planet. This is the only planet that is known to inhabit life.

Mars is the fourth planet. Mars is called the "red planet" and has two moons.

Jupiter is the fifth planet in our solar system. Jupiter is the biggest planet in our solar system.

Saturn is the sixth planet. It has 31 moons.

Uranus is the seventh planet. It is a greenish-blue planet.

Neptune is the eight planet. On Neptune, temperatures stay colder than -350 Fahrenhiet.



Pluto is no longer a planet, but if you weighed 100 pounds on Earth, then you would weight 7-8 pounds on Pluto. But your mass would be the same.
