The main source of energy for atp production through the process of photosynthesis is the sun's heat energy. Basically, it is the main driving force for a plant's metabolic reactions.
Thank you for posting your question here at Brainly. I hope I was able to help.
Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid. However, gases that are contained in a fixed volume cannot expand - and so increases in temperature result in increases in pressure.
Answer:
<h2>100 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 25 × 4
We have the final answer as
<h3>100 J</h3>
Hope this helps you
