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 truck contains both hydraulic brakes (reliability 0.96) and mechanical brakes (reliability 0.99). What is the probability of s
Oksana_A [137]

Answer:

i) 0.9504

ii) 0.0452

Explanation:

Given data: reliability of hydraulic brakes= 0.96

reliability of mechanical brakes = 0.99

So the probability of stopping the truck = 0.96×0.99= 0.9504

At low speed

case: A works and B does not

= 0.96×(1-0.99) = 0.0096

case2 : B works and A does not

= 0.99×(1-0.96) = 0.0396

Therefore, probality of stopping = 0.0096+0.0396 = 0.0492

HELPPP PLEASEEE!!!!!

Answer:

1) The speed of sound increases

2)  440 Hz

3)  29°C

4)  17°C

5) 434 Hz

6)  12 m/s

7)  17.3 m

Explanation:

1) The speed of sound increases

2) V = f×λ

f = V/λ = 343/0.78 = 439.744 ≈ 440 Hz

3) V = f×λ

512 × 0.68 = 348.16 m/s

348.16 - 331 = 17.16

T = 17.16/0.6 = 28.6 ≈ 29°C

4) Increase in speed = 350 - 340 = 10

Increase in temperature = 10/0.6 = 16.67° ≈ 17°C

5) f = V/λ = 343/0.79 = 434 Hz

6) 331 + 0.6×30 - (331 × 0.6 ×10) = 12 m/s

7) V = 331 + 0.6×25 = 346m/s

λ = 346/20 = 17.3 m
