Solution :
Michaelis-Menten kinetics in the field of biochemistry is considered as one of the well known models for enzyme kinetics. The model represents an equation that describes the enzymatic reactions's rate by relating the reaction rate to the substrate's concentration. The equation is named after the two famous scientists, Leonor Michaelis and Maud Menten.
The formula is :
![$v=\frac{V_{max}[S]}{K_M + [S]}$](https://tex.z-dn.net/?f=%24v%3D%5Cfrac%7BV_%7Bmax%7D%5BS%5D%7D%7BK_M%20%2B%20%5BS%5D%7D%24)
where v = velocity of reaction
= maximum rate achieved
= Michaelis constant
[S] = concentration of the substrate, S
According to the question, by putting the velocity of reaction, v as 
, we get the above equation as
![$[S]= \frac{K_M}{3}$](https://tex.z-dn.net/?f=%24%5BS%5D%3D%20%5Cfrac%7BK_M%7D%7B3%7D%24)
Therefore the answer is
Carbon is the answer to the problem
Answer:
Mammography is the process in which low energy radiations are used to diagnose and screening. The purpose of this process is the early detection of the breast cancer. These low energy radiations may have some risks like damaging and burning of cells.
In the current scenario, woman is apprehensive because she has read about the risks of using ionizing radiations. The radiographer should tell her the benefits of the mammography will outweigh its potential consequences. Screening, for instance, will let her know if she is suffering from breast cancer. Cancer is very dangerous disease as compare to very small burning.
In this way radiographer should handle the situation.
Answer:
A. 69.9m
Explanation:
Given parameters:
Initial velocity = 10.5m/s
Final velocity = 21.7m/s
Time = 4.34s
Unknown:
Distance traveled = ?
Solution:
Let us first find the acceleration of the car;
Acceleration = 
v is final velocity
u is initial velocity
t is the time
Acceleration = 
= 2.58m/s²
Distance traveled;
V² = U² + 2aS
21.7² = 10.5² + 2 x 2.58 x S
360.64 = 2 x 2.58 x S
S = 69.9m
