ugh help i have to write a 1 -page essay for my honors sci class
and i have no clue how to its over Photosynthesis but we have to have answer to these questions in it to :(What is photosynthesis? What role does the Sun play in the interaction of energy during photosynthesis? What forms of energy conversion occur? What form does the chemical energy take? What gas do plants release as a result?): so i have no clue how to write it .?.?.?.?.?.?
.

Answers

Answer:

1 . Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities.

2. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.

3.Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water. The process of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce organic compounds and oxygen.

4 . Chemical energy is stored in the bonds that connect atoms with other atoms and molecules with other molecules. Because chemical energy is stored, it is a form of potential energy. When a chemical reaction takes place, the stored chemical energy is released.

What is solar system?

Solar system is defined as the Sun's orbiting objects are confined by gravity to one system. The Solar System is the only system in which a habitable planet has been observed, the only star we can observe up close, and the only planets we can explore with spacecraft. Understanding the creation and evolution of planets as well as the conditions required for life requires extensive investigation into the solar system.

The terminator is the line on the moon that divides day from night. The moon's surface is in a twilight state along the terminator line, which is where the twilight zone is frequently referred to as. The sun is either rising or setting on the moon along this line.

Thus, we only view a portion of the lighted part of the Moon because of how the Moon rotates around the Earth.

John rode 3150 m at an average speed of 350 m/min.If he had ridden at average of 375 m/min instead. How much sooner would it have taken? (In seconds)​

Answers

Answer:

36

Explanation:

It would have taken 36 s for John to cover the distance.

Average speed is defined as the total distance travelled divided by the total time taken.

Average speed = Total distance / total time

To obtain the answer to the question, we'll begin by calculating the time taken to cover the distance (3150 m) in each case.

Case 1:

Average speed = 350 m/min

Total Distance = 3150 m

Time 1 =?

Average speed = Total distance / total time

350 = 3150 / Time 1

Cross multiply

350 × Time 1 = 3150

Divide both side by 350

Time 1 = 3150 / 350

Time 1 = 9 mins

Multiply by 60 to express in seconds

Time 1 = 9 × 60

Time 1 = 540 s

Case 2:

Average speed = 375 m/min

Total Distance = 3150 m

Time 2 =?

Average speed = Total distance / total time

375 = 3150 / Time 2

Cross multiply

375 × Time 2 = 3150

Divide both side by 375

Time 2 = 3150 / 375

Time 2 = 8.4 mins

Multiply by 60 to express in seconds

Time 2 = 8.4 × 60

Time 2 = 504 s

Finally, we shall determine how much sooner it would have taken John to travel at 375 m/min. This can be obtained as follow:

Time 1 = 540 s

Time 2 = 504 s

Difference in Time =?

Difference = Time 1 – Time 2

Difference in time = 540 – 504

Difference in time = 36 s

Therefore, it would have taken John 36 s if he had travelled at an average speed of 375 m/min.
