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

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.

Consider a production line with five stations. station 1 can produce a unit in 9 minutes. station 2 can produce a unit in 10 minutes. station 3 has two identical machines, each of which can process a unit in 12 minutes (each unit only needs to be processed on one of the two machines. station 4 can produce a unit in 5 minutes. station 5 can produce a unit in 8 minutes. which station is the bottleneck station?
