The Hubble Telescope The Hubble Telescope is a large telescope that orbits Earth. It was named after Edwin Hubble. Hubble was an

astronomer. The Hubble was launched in 1990 by NASA, the United States' space program. It uses a 94- inch mirror to collect light. Data are sent back to Earth by radio. Since it is above Earth's atmosphere, it gives us clearer pictures of space than telescopes on Earth can. It can also see farther. With this powerful tool, we've learned a lot about the universe. What Scientists Have Learned from the Hubble The Hubble has allowed us to watch stars form. It also has let us see into distant galaxies. We've been able to test our ideas. For example, before the Hubble, black holes were just a theory. We didn't know for sure that they existed. The Hubble has shown us evidence of black holes in space. The telescope has helped us find places to land data-gathering robots on Mars. We've used it to track the paths of comets. We've also been able to see volcanoes erupt on 10, one of Jupiter's moons. Telescopes that are larger than the Hubble are now being created But the Hubble is the first of its kind.
Why does being in outer space make Hubble a better telescope?

A uniform plank of mass 10kg and length 10m rests on two supports, A and B as shown. A boy of weight 500N stands at a distance o
kifflom [539]

Answer:

U² = 142.86 N

U¹ = 357.14 N

Explanation:

Taking summation of the moment about point A, we get the following equilibrium equation: (taking clockwise direction as positive)

W(2\ m) - U^2(7\ m) = 0

where,

W = weight of boy = 500 N

U² = reaction ay B = ?

Therefore,

(500\ N)(2\ m)-(U^2)(7\ m)=0\\U^2=\frac{1000\ Nm}{7\ m}\\

<u>U² = 142.86 N</u>

Now, taking summation of forces on the plank. Taking upward direction as positive, for equilibrium position:

W-U^1-U^2=0\\500\ N - 142.86\ N = U^1\\

<u>U¹ = 357.14 N</u>

A starship travels to a planet that is 20 light years away. The astronauts stay on the planet for 2.0 years before returning at
ad-work [718]

Answer:

astronauts age is 32 years

correct option is e 32 years

Explanation:

given data

travels = 20 light year

stay = 2 year

return = 52 years

to find out

astronauts aged

solution

we know here they stay 2 year so time taken in traveling is

time in traveling = ( 52 -2 )  = 50 year

so it mean 25 year in going and 25 years in return

and distance is given 20 light year

so speed will be

speed = distance / time

speed = 20 / 25 = 0.8 light year

so time is

time = \frac{t}{\sqrt{1-v^2} }

time =  \frac{25}{\sqrt{1-0.8^2} }

time = 15 year

so age is 15 + 2 + 15

so astronauts age is 32 years

so correct option is e 32 years
