the simulation kept track of the time and automatically recorded data on cart displacement and velocity. if the cart trials were run with a real cart and fan using meter sticks and stopwatches, how might the data compare? check all that apply.\nthere would be variables that would be hard to control, leading to less reliable data.\nthe data would be just as valid if it were recorded with a stopwatch.\nmeter sticks may lack precision or may be read incorrectly.\nreal fans will always perform exactly the same as virtual fans.\nhuman error in recording or plotting the data could be a factor.

Answer

Brief Explanations:

  1. In real - world experiments, there are many uncontrollable variables like air currents, surface friction variations, etc., which can make data less reliable.
  2. Stopwatch and meter stick measurements are subject to human error and may not be as accurate as automated simulation data recording, so the data may not be as valid.
  3. Meter sticks have limited precision and can be misread by humans.
  4. Real fans may have variations in performance due to manufacturing tolerances, wear - and - tear, etc., and won't always perform like virtual fans.
  5. Humans can make errors in recording values from meter sticks and stopwatches or in plotting the data on a graph.

Answer:

There would be variables that would be hard to control, leading to less reliable data. Meter sticks may lack precision or may be read incorrectly. Human error in recording or plotting the data could be a factor.
