Answer -

314.74 \frac{m}{s^2}

Explanation

As per the equation of Newton's third law of motion we know that -  

 V_f^2 - V_0^2 = 2aS

where  

 V_f

is the final speed  

and  

 V_0

is the initial speed.  

a is the acceleration and S represents the speed.  

Given  

Final velocity  = 33

 

centimeter per second, Initial velocity is equal to zero and the distance traveled is equal to  

 1.73

centimeter

Now, substituting the values in above equation, we get -

33^2 - 0 = 2 * a* 1.73\\a = 314.74

A chloroplast is releasing large amounts of oxygen. what does this tell you about what other processes are going on inside the c
PtichkaEL [24]
Chloroplasts are organelles within plant cells that contain chlorophyll and are responsible for carrying out photosynthesis. This process which is utilised by plants to manufacture food, requires carbon dioxide and water which is then converted into glucose and oxygen. Therefore, the release of oxygen tells us that photosynthesis is occurring inside the chloroplast.
