The runner below has a mass of 55 kg and is moving at 3.87 m/s. what is his kinetic energy in joules
sweet-ann [11.9K]

Answer:

<h2>411.86 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass

v is the velocity

From the question we have

k =  \frac{1}{2}  \times 55  \times  {3.87}^{2}  \\  = 27.5 \times 14.9769 \\  = 411.86475

We have the final answer as

<h3>411.86 J</h3>

Hope this helps you

In your own words, give a brief overview of the process of photosynthesis. Include where each phase place within a plant cell.
vodka [1.7K]

Answer:

Photosynthesis has two parts: the light-dependent reactions and the dark reactions (the Calvin cycle). Photosynthesis in a general sense, uses CO2 and water to create C6H12O6 (glucose) and oxygen. The light-dependent reactions use water to make oxygen, and a reduced energy carrier (NADPH) is also created. The Calvin cycle uses carbon dioxide and ATP to create G3P for glucose.

The light-dependent reactions occur on the membrane of the thylakoid and also involve shuttling electrons across different complexes (photosystem II and photosystem I), eventually causing ATP to be created with a proton gradient.

The light-independent reactions/Calvin cycle occur in the stroma of the chloroplast and also involve shuffling carbons around. Carbon dioxide is processed in three stages, and glucose is made from 6 CO2.
