3
$100 Question from Light-Year Is light year measuring distance or time?
4
$100 Answer from Light-Year distance
5
$200 Question from Light-Years What is the speed of light?
6
$200 Answer from Light-Year 300 000 km/s
7
$300 Question from Light-Year When comparing the distance from Earth to different stars, which unit is the most appropriate? -Light hour -Kilometer -Light-Year -Astronomical unit
8
$300 Answer from Light-Year Light-Year
9
$400 Question from Light-Year What is 9.5 trillion kilometers?
10
$400 Answer from Light-Year one light year
11
$500 Question from Light-Year Let us say a star just exploded into a supernova 9 million km away. How long will it take its radiation to reach our solar system? -30 years -750 hours -30 seconds
12
$500 Answer from Light-Year 30 seconds
13
$100 Question Triangulation? What is the use of triangulation?
14
$100 Answer from Triangulation A technique for determining the distance to A visible object by creating an imaginary triangle between the observer and the object then calculating the distance.
15
$200 Question from Triangulation Which calculations are necessary to perform a triangulation measurement? a) a straight baseline length b) two angle measurements c)a tan(theta) calculation d)a scale calculation
16
$200 Answer from Triangulation b) two angle measurements c)a tan(theta) calculation d)a scale calculation
17
$300 Question from triangulation Why do you need to have a baseline to make a triangulation measurement?
18
$300 Answer from Triangulation Baseline provides a framework for the angles. The longer baseline would give you a more accurate angle measurement
19
$400 Question from Triangulation What are the 3 measurements you need for triangulation?
20
$400 Answer from Triangulation Two angles and the length of a baseline
21
$500 Question from Triangulation Why is it best to use a long baseline when determining distances using triangulation?
22
$500 Answer from Triangulation Gives you more accurate angle measurement.
23
$100 Question from parallax What is paralax
24
$100 Answer from Parallax The apparent shift of an object against stationary background caused by change in position of observer.
25
$200 Question from Parallax What causes parralax
26
$200 Answer from Parallax Parallax is caused by change in position of the observer
27
$300 Question from Parallax Why is parallax not allways accurate
28
$300 Answer from Parallax The farther an object is the less accurate a measurement is because the change of angles
29
$400 Question from Parallax Why is parallax so time consuming when measuring distant objects
30
$400 Answer from Parallax When measuring things far from earth to create baseline you must measure when earth reaches its farthest points every 6 months
31
$500 Question from Parallax How do astronomers get accurate measurements in parallax?
32
$500 Answer from Parallax They create a larger baseline which helps with making accurate measurements in parallax
33
$100 Question from Challenge If a galaxy is 1.5 million light year away how long will it take the light to travel from the galaxy to Earth. a)1.5 billion years b)1.5 thousand years c) 1.5 million years
34
$100 Answer from Challenge c)1.5 million years
35
$200 Question from Challenge Why is a scale used in triangulation?
36
$200 Answer from Challenge makes the numbers smaller and easier to work with.
37
$300 Question from Challenge the Oort cloud is about 700,000 times as far from earth as earth is from the sun. How far away is the Oort cloud. a)700 000AU b)700AU c)7AU
38
$300 Answer from Challenge A) 70,000AU
39
$400 Question from Challenge How does long does it take light to travel from the sun to Earth a)1hour b)7mins c)8.3mins
40
$400 Answer from Challenge c) 8.3mins
41
$500 Question from Challenge Explain the difference between triangulation and Parllax?
42
$500 Answer from Challenge Parallax is used for star’s distance from earth while triangulation is used for distant object.
43
$100 Question from Challenge What is astronomical unit?
44
$100 Answer from Bonus Used to measure distances within the solar system
45
$200 Question from Bonus How many kilometers does 1AU equal a)100 00km b)500km c)150 million km
46
$200 Answer from Bonus d)150 million
47
$300 Question from Bonus Why are the distances between bodies in solar systems not measured in light years?
48
$300 Answer from Bonus The distances between bodies in solar systems are not big enough to be measured in light years
49
$400 Question from Bonus Which of the following units is the greatest distance? a)One light year b)One parallax c)One astronomical units
50
$400 Answer from Bonus a)One light year
51
$500 Question from Bonus When comparing the distance from Earth to different stars which unit is most appropriate? a)Astronmical unit b)Kilometre c)Light year
52
$500 Answer from Bonus c)Light year
53
Final Jeopardy Parallax and triangulation are considered to be indirect measurement techniques. Why are such techniques used to measure distances in space?
54
Final Jeopardy Answer It’s not possible to physically measure the long distances between stars. For these reasons, astronomers use a number of techniques to measure distances indirectly. Two such techniques have been used for thousands of years to determine distances on Earth: triangulation and parallax.
