Answer:
Step-by-step explanation:
length times width = area
so you have 8.5w=93.5
divide 8.5 on both sides to get your answer
w= 11
so your width must be 11 inches
Answer:
256.
Step-by-step explanation:
1 × 4 = 4
4 × 4 = 16
16 × 4 = 64
64 × 4 = 256
Part A
Given that

Then,

For

, then

Thus,

For

, we have

Part B
Recall that from part A,

Now, at initial position, t = 0 and

, thus we have

and when the velocity drops to half its value,

and

Thus,

Thus, the distance the particle moved from its initial position to when its velocity drops to half its initial value is given by
Answer:
A = 0.84
Step-by-step explanation:
The absorbance of the myoglobin solution can be calculated by using the Beer-Lambert law:

<u>Where:</u>
<em>A: is the absorbance </em>
<em>ε: is the molar attenuation coefficient = 15,000 M⁻¹cm⁻¹ </em>
<em>l: is the optical path length = 1 cm</em>
<em>C: is the concentration = 1 mg/ml </em>
Since the concentration is given in mg/ml and the molar attenuation coefficient is given in M (mol/L) we need to convert the concentration in mg/ml to mol/L and for that, we need to use the molecular weight of myoglobin = 17.8 kDa = 17.8x10³ g/mol:

Now, we can calculate the absorbance of the myoglobin:

Therefore, the absorbance of the myoglobin solution is 0.84.
