There is a basic difference<span>, because </span>mass<span> is the actual amount of material contained in a body and is </span>measured<span>in kg, gm, etc. Whereas </span>weight<span> is the force exerted by the gravity on that object mg. Note that </span>mass<span> is independent of everything but </span>weight<span> is different on the earth</span>

Answer: B) used to drive an endergonic reaction
Explanation:
coupling occurs when the energy released by an exergonic reaction is used to drive an endergonic reaction. Exergonic reactions are reactions that lose energy as the process takes place while endergonic reactions are reactions that require energy to be driven.
Am example of an exergonic reaction is cellular respiration and an example of a endergonic reaction is Photosynthesis The coupling of the two reactions can work to the advantage of the reactions to give them enough drive to be completed.
Answer:
Work= -7.68×10⁻¹⁴J
Explanation:
Given data
q₁=q₂=1.6×10⁻¹⁹C
r₁=2.00×10⁻¹⁰m
r₂=3.00×10⁻¹⁵m
To find
Work
Solution
The work done on the charge is equal to difference in potential energy
W=ΔU
The motion would be best described as B) an up-and-down motion on the surface of the earth
