You cook a turkey until the internal temperature reaches 180°f. the turkey is placed on the table until the internal temperature reaches 100°f, and it can be carved. when the room temperature is 72°f, the cooling rate of the turkey is $r=0.067$ . how long do you have to wait until you can carve the turkey? use newton's law of cooling to solve the problem. round your answer to the nearest whole minute.
The newton's law of cooling is used to determine the waiting time
You will have to wait for 20 minutes to carve the turkey
How to determine the time?By newton's law of cooling, we have:
[tex]T = (T_o - T_R) e^{-rt} + T_R[/tex]
From the question, we have:
T = 100°f ---- The serving temperature
To = 180°f --- The initial temperature
TR = 72°f ----- the room temperature
r = 0.067 -- the cooling rate
So, we have:
[tex]T = (T_o - T_R) e^{-rt} + T_R[/tex]
[tex]100 = (180 - 72) e^{-0.067t} + 72[/tex]
Subtract 72 from both sides
[tex](180 - 72) e^{-0.067t} = 28[/tex]
Evaluate the difference
[tex]108 e^{-0.067t} = 28[/tex]
Divide both sides by 108
[tex]e^{-0.067t} = 0.25923[/tex]
Take the natural logarithm of both sides
[tex]-0.067t = -1.3500[/tex]
Divide both sides by -0.067
[tex]t = 20.149[/tex]
Approximate
[tex]t = 20[/tex]
Hence, you will have to wait for 20 minutes to carve the turkey

The surface tension of water in air is approximately 0.00518 lbf/ft. if the atmospheric pressure is 14.7psia, what is the pressure inside a droplet 0.01" in diameter?
Based on the calculations, the pressure inside this droplet is equal to 2,909.35 kPa.
Given the following data:
Surface tension = 0.00518 lbf/ft to N/m = 0.00702 N/m.Atmospheric pressure = 14.7psia to kPa = 101.35 kPa.Diameter = 0.01 mm to m = 0.00001 m.Radius, r = [tex]\frac{diamter}{2} =\frac{0.0001}{2}[/tex] = 0.000005 m.
How to determine the pressure inside a droplet.For a droplet with only one surface, its pressure is given by this formula:
[tex]P_1-P_2=\frac{2 \tau}{r} \\\\P_1=\frac{2 \tau}{r}+P_2[/tex]
Substituting the given parameters into the formula, we have;
[tex]P_1=\frac{2 \times 0.00702}{0.000005} + 101.35\\\\P_1=2808+ 101.35[/tex]
Inside pressure = 2,909.35 kPa.

Antigens are foreign proteins that invade the systems of organisms. Vaccines function by stimulating an organism’s immune system to develop antibodies against a particular antigen. Developing a vaccine involves producing an antigen that can be introduced into the organism being vaccinated and which will trigger an immune response without causing the disease associated with the antigen. Certain strains of bacteria can be used to produce antigens used in vaccines
The process described above is about how vaccines are designed using antigens.

How many ways can you listen to 3 songs from a cd that has 12 selections?
Taking into account the definition of permutation, there are 1320 ways you can listen to 3 songs from a cd that has 12 selections.
What is permutationPermutations refer to the action of arranging all the members of a set in some kind of order or sequence. This means that if a set is already ordered, the process of rearranging its elements is called permutation.
In other words, permutations of m elements in n positions are the different ways in which the m elements can be arranged occupying only the n positions.
In this case, the elements are not repeated, since if they are repeated or equal to each other, exchanging them does not generate a new permutation. And the order does matter, since the exchange between two different elements generates a new permutation
To obtain the total of ways in which m elements can be placed in n positions, the expression is used:
[tex]P=\frac{m!}{(m-n)!}[/tex]
The sign ! indicates the factorial function, which indicates that all positive integers between the number that appears in the formula and the number 1 must be multiplied.
Number of ways you can listen to 3 songsThe order in which songs are listening is important as there is no plan to listen to the same song twice. So, the permutation can be applied.
Being:
m=12n=3and replacing in the expression for permutation, you get:
[tex]P=\frac{12!}{(12-3)!}[/tex]
[tex]P=\frac{12!}{9!}[/tex]
[tex]P=\frac{479001600}{362880}[/tex]
P= 1320
