Answer:

My Dear Friend

It's seen storms being generated in Saturn's clouds, it's recognized that Saturn's blue haze fades a bit in the hemisphere receiving less sunlight. It's identified about 8 new moons (Probably more, now...) and has measured the mass & density of it's moons. Some of them are very light - for their size, some appear to be composed of just empty space.

It solved the riddle of Japetus - for almost 300 years, astronomers have seen that it's 8 to 10 times more reflective on one side than the other - and, it's due to dark, sun-melted material collecting on it's leading edge, while bright ice crystals remain on the trailing side.

It was Voyager that first spotted the hexagon-shaped structure at Saturn's poles, but it was Cassini that sent us detailed photos of it - and, it's thought to be due to Saturn's rapid rotation coupled with the winds in it's atmosphere.

Cassini also flew through the water geysers of Encelaudus, and detected simple amino acids in the spray; and radar-mapped Titan, detecting flat areas that are thought to be liquid methane and ethane lakes - the first body besides Earth with liquid on the surface.

I hope this answer helps you

Answer:

It helped us learn that Saturn’s moons are unique worlds with their own stories to tell. The rings of Saturn are dramatic processes operating within them. It also observed weather and seasonal changes of other planets.

A physics student throws a softball straight up into the air. The ball was in the air for a total of 3.56 s before it was caught

meriva

Answer:

The initial velocity of the softball is 14.711 meters per second.

Explanation:

This is a case of an object which experiments a free fall, that is, an uniform accelerated motion due to gravity and in which effects from air friction and Earth's rotation can be neglected.

From statement we must understand that the student threw the softball upwards and it is caught at original position 3.56 seconds later. Initial and final heights, time and gravitational acceleration are known and initial speed is unknown. The following equation of motion is used:

$y = y_{o} + v_{o}\cdot t + \frac{1}{2}\cdot g \cdot t^{2}$ (Eq. 1)

Where:

$y_{o}$ - Initial height of the softball, measured in meters.

$y$ - Final height of the softball, measured in meters.

$v_{o}$ - Initial velocity of the softball, measured in meters per second.

$t$ - Time, measured in seconds.

$g$ - Gravitational acceleration, measured in meters per square second.

If we know that $y = y_{o}$ , $t = 3.56\,s$ and $g = -9.807\,\frac{m}{s^{2}}$ , the initial velocity of the softball is:

$v_{o}\cdot (3\,s)+\frac{1}{2}\cdot (-9.807\,\frac{m}{s^{2}} )\cdot (3\,s)^{2} = 0$

$3\cdot v_{o} -44.132\,m= 0$

$v_{o} = 14.711\,\frac{m}{s}$

The initial velocity of the softball is 14.711 meters per second.

When finding the upper bound of the density, you put what number in the denominator?

lilavasa [31]

Answer: The result of "the upper bound of the density" does not go on the denominator.
So simplified, no. The answer is no.
