Question

Our data for how much force is needed can be qualitative. This means we don’t have to know exact values for the force in Newtons. Let’s use a scale of 1-5 to rank how much force we apply each time.
6. How many different masses should we use?

How many trials should we do for each mass?

Answer 1

Answer:

For macroscopic objects, we use units such as grams and kilograms to state their masses, but. There will not be much error if you estimate the mass of an atom by simply. to what we did for our hypothetical example, but the percentages are different: Add two atomic masses of carbon and six atomic masses of hydrogen:

Explanation:

Answer 2

Answer:We use units such as grams and kilograms to denote their masses for macroscopical objects. However. If you actually measure an atom's mass, there would be not much error. In our theory, however, percentages vary: add two carbon atomic masses and six hydrogen atomic masses:
