Becasue steel particles may contaminate the flour.
Answer:
a.0.120mm
b.1.58s
c.0.6329Hz
Explanation:
a. Given that 0.120mm is displaced from equilibrium, 0.120mm after 0.790s on opposite side:
-The amplitude is the maximum displacement from equilibrium.
-The object goes from x=+A to x=-A and back during one cycle.
#Hence, the amplitude of the motion is 0.120mm
b.Motion from maximum positive displacement to maximum negative displacement takes places during half the period of Simple Harmonic Motion(SHM)

#Hence, the period of the motion is 1.58s
c. Frequency is calculated as one divided by the period of the motion.
From b above we know that the motions period is 1.58s
Therefore:
<em>Frequency=1/period=1/1.58=0.6329Hz</em>
<em>#</em><em>The frequency of the motion is </em><em>0.6329Hz</em>
Answer: One of the units used to measure incident energy is calories per centimeter squared (cal/cm2).
Explanation: Incident energy this is defined as the amount of thermal energy impressed on a surface, at a certain distance from the source, generated during an electrical arc event.
The working distance is the distance from where the worker stands to the source location. The most common distance for which incident energy has been determined in tests is 18 inches.
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 ![$[S]= \frac{K_M}{3}$](https://tex.z-dn.net/?f=%24%5BS%5D%3D%20%5Cfrac%7BK_M%7D%7B3%7D%24)
