Explanation:
either C or A but A seems unlikely after multiple attempts. Although the question doesn't make it clear whether the balance is electric either way it could be wrong in someway and seems to be the most likely.
Answer:
28500
Explanation:
Force equation - F = m * a
F = 950 * 30
F = 28500
Answer:
theory
Explanation:
<em>A scientist can contribute to the formation of a theory in a particular subject by conducting research along the line of that subject.</em>
Conducting research requires the formation of a hypothesis and testing the hypothesis by conducting a relevant experiment during which data are gathered, analyzed, and interpreted in order to falsify or accept the hypothesis.
A good experiment must be replicate-able. When the same experiment is repeated by different independent researchers and the same conclusion is arrived at, this could potentially lead to the formation of a theory.
<u>Hence, a scientist can contribute to the formation of a theory by conducting an experiment with replicability in order to test a hypothesis.</u>
You would have done 240 joules of work on the box.
Work = (force) x (distance)
= (60 newtons) x (4 meters)
= 240 joules .
