Are these good scientific questions (they are written in reference to a computer simulation)?

1. How does the range of the object change as the initial speed and drag coefficient get bigger?

2. Does air resistance affect the time taken for the object to complete its trip?

3. How does reducing the speed and angle (in the interval 10 < x < 40) affect the object's range?

These are indeed good scientific questions, as they investigate the relationship between various variables in a computer simulation. Here's how you can approach finding the answers to each question:

1. To determine how the range of the object changes with increasing initial speed and drag coefficient, you can design and run multiple simulations with different combinations of initial speed and drag coefficient. Record the range achieved in each simulation and analyze the data to identify any patterns or trends. By comparing the results, you can draw conclusions about the relationship between these variables and the range of the object.

2. To investigate the effect of air resistance on the time taken for the object to complete its trip, you can again set up multiple simulations where you vary the presence or magnitude of air resistance. Keep other variables constant, such as initial speed and angle. By comparing the time taken in each simulation, you can determine whether air resistance has an impact on the duration of the object's trip.

3. If you want to explore how reducing the speed and angle within the interval of 10 < x < 40 affects the object's range, you can run simulations with different combinations of speed and angle within this range. Record the range achieved in each simulation and observe any patterns. By examining the results and analyzing the relationship between speed, angle, and range, you can gain insights into the impact of reducing these variables on the object's range.

Remember, scientific questions often require experimentation and data analysis to arrive at reliable answers.
