Question

Spider-Man and Ned were testing the distance he could shoot his web depending on the angle at which he points his web shooter. He tested this 3 times at each angle.

0°: 18.2m, 16.7m, and 17.9m
45°: 79.6m, 74.3m, and 76.2m
75°: 62.4m, 61.5m, and 62.7m

What is the Independent variable?
Question 1 options:

The distance spider-man’s web shoots
The angle at which spider-man points his web shooter
Testing each angle 3 times
The location where they are testing

What is the dependent variable?

Question 2 options:

The distance spider-man’s web shoots
The angle at which spider-man points his web shooter
Testing each angle 3 times
The location where they are testing


Look at the 1st graph below, which location has the warmest temperatures in July?
Question 3 options: See Picture below

Barrow, Ak
Christchurch, NZ
Quito, Equador
Madison, WI

According to the 1st graph below, which location does not experience seasonal temperature fluctuations?

Question 4 options:

Barrow, AK
Quito, Equador
Christchurch, NZ
Madison, WI

Use the 2nd chart below to answer the following question. If cool stars are red and hot stars are blue, where would a bright (highly luminous) blue star be found on a Hertzsprung-Russell diagram?

Question 5 options:

Upper right
Lower right
Upper left
Lower left

A group of scientists has developed a computer program that will predict the phase that a star will be after a certain number of years. The scientists used data from real stars to teach the computer how the universe works. Now, it can be used to quickly run a simulation of what would likely happen over billions of years in the universe.

A group of students is wondering the rate at which a star progresses through life. They plan two experiments using computer simulations. They ran each simulation from the protostar phase 100 times and recorded the outcomes.

In Experiment 1 they used one size of star (1 solar mass) and compared seven different lengths of time. In Experiment 2 they used one length of time and 3 different sizes of stars (1, 15, and 30 solar masses). The results of both experiments are below in Figure 2

According to the 3rd data chart in which is the best conclusion of the changes occurring from 5-10 billion years?

Question 6 options:

Main sequence stars are becoming red giants.
Protostars are becoming red giants.
The stars are becoming black holes.
The stars are exploding.

Answer 1

3. Madison, WI

4. Quito, Equador

6. Main Sequence stars are becoming red giants

Step-by-step explanation:

Answer 2

1) The angle at which spider-man points his web shooter

2) The distance spider-man’s web shoots

3) Madison, WI

4) Quito, Equador

5) Upper left

6) Main sequence stars are becoming red giants.

Step-by-step explanation:

1) The experimenters are choosing the angle at which to point the web shooter. This means the angle at which they shoot is independent of the other variables.

2) The distance the web shoots is not chosen by the experimenters and depends on the angle at which it is shot.

3) July is the 7th month and the graph for Madison, WI shows temperatures exceeding all other locations at this time.

4) Fluctuations refer to a changing of temperatures over seasons. Since Quito, Equador has a flat graph, this indicates no fluctuations.

5) This graph plots the hottest (blue) stars on the left and the highest luminosity (bright) stars at the top. Thus, bright blue stars are plotted in the top left.

6) At 5 billion years there are 0 giants and 100 main sequence stars. At 10 billions years there are 94 giants and 6 main sequence stars. This shows that the main sequence stars are becoming giants.
