Please give answer.
Describe, with the aid of suitable diagrams, the basic structure and components of the ATLAS detector at the LHC.
In a globular cluster, astronomers (someday) discover a star with the same mass as our Sun, but consisting entirely of hydrogen and helium. Is this star a good place to point our SETI antennas and search for radio signals from an advanced civilization?
Group of answer choices
No, because such a star (and any planets around it) would not have the heavier elements (carbon, nitrogen, oxygen, etc.) that we believe are necessary to start life as we know it.
Yes, because globular clusters are among the closest star clusters to us, so that they would be easy to search for radio signals.
Yes, because we have already found radio signals from another civilization living near a star in a globular cluster.
No, because such a star would most likely not have a stable (main-sequence) stage that is long enough for a technological civilization to develop.
Yes, because such a star is probably old and a technological civilization will have had a long time to evolve and develop there.

1)
Astronauts orbiting the earth in the space shuttle experience a force of gravity that is
several times greater than the Fgrav experienced on Earth's surface.
several times smaller than the Fgrav experienced on Earth's surface.
a fraction greater than the Fgrav experienced on Earth's surface.
a fraction smaller than the Fgrav experienced on Earth's surface .
... nonsense! Orbiting astronauts do not experience any gravitational pull from the earth.
a)
A space shuttle is in orbit about the earth at an altitude where the acceleration due to gravity is 8.70 m/s 2. What is the shuttle's speed at this altitude?

- Would you expect to find an earthlike planet (with a solid surface) around a very low-mass star that formed right at the beginning of a globular cluster’s life? Explain.arrow_forwardSuppose that stars were born at random times over the last 10e10 years. The rate ofstar formation is simply the number of stars divided by 10e10 years. The fraction ofstars with detected extrasolar planets is at least 9 %. The rate of star formation can bemultiplied by this fraction to find the rate planet formation. How often (in years) doesa planetary system form in our galaxy? Assume the Milky Way contains 7 × 10e11 stars. I've done this problem 3 different times from scratch and looked at similar problems here. Each time my answer is 1.587 (1.59 rounded to 2 significant figures), but when I submit, it says the answer is wrong. What do you think?arrow_forwardA halo CME is observed moving away from the Sun.
