The purpose of an experiment is to LEARN the EFFECT of something.
The way you do that is to CHANGE the thing and see what happens.
You can change as many things as you want to. But If you change
TWO things and observe the result, then you don't know which one
of them caused the effect you see.
Or maybe BOTH of them working together caused it. You don't know.
So your experiment is not really much good. You need to do it again.
The force of gravity = GMm / r^2, where G is gravitational constant, M is mass of one object, m is mass of another object, r is distance between them.
To make gravity smaller, decrease mass or increase distance.
To make gravity bigger, increase mass or decrease distance.
Answer:
constant volicty of the pumper when they hit ground 7.03-/s
These values when compared seem to be the same. They are equal. If we convert them to the same units, they results to the value which is:
51.5 Hectograms = 5100 Grams
51,500 Decigrams = 5100 Grams
Hope this answers the question. Have a nice day.
