Answer: because of air resistance. See explanation for further details.
Explanation: Galileo performed an experiment to proof that the time of descent of two different masses is independent of time.
But in reality this is most likely not true because of air resistance and other fluid frictional effects in consideration.
If the experiment is performed in a vacuum, it will always be true that time is independent of masses of two falling objects.
Answer:
I think the answer is A but I could be wrong but I think the answer is A. please let me know if I am wrong.
Answer:
Explanation:
Given

Determine the velocity when t = 8
This type of velocity is referred to as an instantaneous velocity.
In this case, it is calculated using
Given that s(t) models the distance;
s(8) = distance at 8 seconds
So;
Option B answers the question
There are no measurements to work with. you'll need to measure the indicated lines with a ruler (most likely in cm) in order to obtain data to use!
They either push or pull and make the object magnetic.
