Suppose I wanted to answer this question about the model.
What info about the model would I need to know in order to
make any intelligent guess about the model ?
Hint:
It would really help if I could SEE the model, or at least a photo of it.
Answer:
Explanation:. The vending machine holds 10 bags of pretzels and 8 packs of cheese crackers. Both the pretzels and crackers dispenseat 2 bags per hour. How many hours will elapse when there is the same number of snacks remaining in the vending machine? How many of each item will there be at this point?Equation1______________________________Equation2_______________________________Hours: ___________________________ Items: ____________________________What does each equation have n common? ______________________How does this affect the solution?
Answer:
Explanation:
Rachel and Sarah are standing on horizontal ground . Let T₁ be the tension between Rachel and Sarah and Sarah is in between you.
Force = mass x acceleration
Apply this equation on Rachel
T₁ = 23 x 2 = 46 N
Let T₂ be tension between Sarah and me and it is inclined at 60°
Force = mass x acceleration
Apply this equation on Sarah
T₂ cos 60 - T₁ = 23 X 2 = 46
T₂ cos 60 - 46 =46
T₂ cos 60 = 92
T₂ = 92 / .5
= 184 N
The pressure of nitrogen which is needed to maintain a N2 concentration of 0. 53 m is 3.2 × 10^(4).
<h3>What is pressure? </h3>
It is defined as the continuous physical force applied on or against an object by something which is in contact with it.
It is also defined as the force per unit area.
<h3>What is henry's law? </h3>
The henry law constant is thr ratio of the partial pressure of compound in air to the concentration of compound in water at given temperature.
C= kp
where,
C is the concentration of compound = 0.53m
k is the henry constant = 6. 2×10−4matm
p is the pressure of compound
By substituting all the value we get,
C = 6. 2×10−4 × p
0.53 = 6. 2×10−4 × p
p = 0.53/6. 2×10−4
p = 3.2 × 10^(4)
Thus we find that the pressure needed to maintain a N2 concentration of 0. 53 m is 3.2 × 10^(4).
