What are some of the things that the Cassini spacecraft has helped us learn about Saturn and its features

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.

What is the value of the angle of refraction of light from a crown glass slab when the angle of incidence is 50°? The slab has a
Artemon [7]

The angle of refraction is 30.3^{\circ}

Explanation:

Refraction is a wave phenomenon that occurs when a light wave passes through the interface between two mediums. When this occurs, the speed and the direction of the light wave change.

We can find the final direction of the refracted light in this problem by applying Snell's law:

n_i sin \theta_i = n_r sin \theta_r

where

n_i, n_r are the index of refraction in the first and second medium, respectively

\theta_i, \theta_r are the angle of incidence and refraction, respectively

In this problem, we have:

n_i = 1.00 (the first medium is air, which has a refractive index of 1.00)

n_r = 1.52 (index of refraction of crown glass)

\theta=50^{\circ} is the angle of incidence

Solving for \theta_r, we find the angle of refraction

\theta_r = sin^{-1}(\frac{n_i sin \theta_i}{n_r})=sin^{-1}(\frac{(1.00)(sin 50^{\circ})}{1.52})=30.3^{\circ}

g HW 5.6.The Moon and the Earth both orbit the center of mass of the Earth-Moon system.Earth is 81 times more massive than the M
Law Incorporation [45]

Answer:

R_{cm}  = 4.688 106 m

Explanation:

The expression for the center of mass is

       R cm = 1 / M ∑ r_{i} m_{i}

Where M is the total mass of the system, ri and m1 are the distance and mass of each particle from a defined origin

Let's look for the total mass, the mass of the moon is m and that of the earth Me

    M = M_{e} + m

    M = 81m + m

    M = 82 m

The distance from the earth to the moon is R = 384.4 106 m

    R_{cm} = 1 / M (M R1 + m R)

   R_{cm}  = 1 / 82m (0 + m R)

    R_{cm}  = R / 82

   R_{cm}  = 384.4 106/82

   R_{cm}  = 4.688 106 m

The radius of the earth is

    R_{e} = 6371 103 m

    R_{e}  = 6.371 106 m

We can see that the center of mass of the system is within the beating radius
