Which of the following brain-scanning techniques is correctly matched with its description?

 -1.5 magnitude Sirius appears 25x brighter than 2 magnitude Polaris.  “All neutron stars are pulsars, but not all pulsars are neutron stars” FALSE  “Spectroscopic Binary” is the term given to a pair of stars that we can determine are orbiting each other only by measuring their periodic Doppler shifts.  A 6.8 solar mass neutron star does NOT exist.  A loop of gas and charged particles following the magnetic field lines between sunspot’s poles is a Prominence/...

What is the difference between brightness and luminosity? - Brightness is how it appears to us, distance is a factor. Luminosity is how much total light a star gives off. What is parallax? - Over the course of a year, the star's position in the sky appears to shift back and forth, returning to its original position 1 year later. The amount of this shift— the angle between one extreme in the star's apparent motion and the other— is equal to twice the parallax. You can use parallax to fin...

The apparent motion of a foreground object relative to a distant background as the observers position changes? - Parallax When measuring parallax the distance between two observation points is called? - Baseline If Earth rotated twice as fast as it currently does, but its motion around the Sun stayed the same, then? A. The night would be twice as long B. The night would be half as long C. The year would be half as long D. The length of the day would be unchanged. - B. A long, thin cloud ...

Stellar Parallax Correct Answer-Shift of position of nearby star in comparison to distant objects. D=1/p (Distance in parsecs, parallax in arc seconds) Only works for nearby stars (within 3000 light years) because you need to measure the parallax angle which becomes smaller as distance increases. You use the position of the star in comparison to other further away stars. Mars Correct Answer-.11 Earth Masses 260 degrees K no evidence for life, no methane (could have supported life in the p...

This exam is entirely multiple choice or true/false. A=T, B=F TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false. 1) The photosphere is about 100 times the diameter of the Earth, and large sunspots are larger than our whole planet. 1) 2) Granulation is the most obvious proof of solar convective energy transport. 2) 3) The solar corona is much cooler than the Sun's surface, hence we must wait for a total solar eclipse to glimpse it with the naked eye. 3)...

GEODESY Exam Questions with Correct Answers 100% Verified 2024 The free-air gravity anomaly height correction for every meter above sea level is _____ mgal. A. + 0.3086 B. - 0.3086 C. + 0.3608 D. - 0.3608 - Correct Answer -0.3086 The forward and back azimuths of a geodetic line do NOT differ by exactly 180 degrees due to the _____. A. location of the observer. B. length of observation C. convergence of the meridians D. difference in instruments - Correct Answer convergence of the mer...

You learned about the general concept of parallax in Chapter 2, and the video offers a review of the basic ideas. To check your understanding of the concept, which of the following is a valid way of demonstrating parallax for yourself? a. Get a camera, and photograph a person who is running back and forth. b. Hold up your hand in front of your face, and move it slowly back and forth. c. Hold up your hand in front of your face, and alternately close your left and right eyes. d. Look up ...

To find the most accurate distance to a nearby star using parallax, astronomers could compare the view of the star against the background stars at what times of the year? - In January and July Which of the following correctly expresses the distance to a nearby star? - 1.3 parsecs Consider two stars (Y and Z) that both exhibit parallax. Star Z appears to move back and forth against the background stars by a greater amount than Y. Which star is farther away from Earth? - Star Y A star has a p...
