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

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 wavelength of the wave traveling at the given velocity and frequency is 3m.

Given the data in the question;

Wavelength is simply defined as the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

It is expressed as;

[tex]\lambda = \frac{v}{f}[/tex]

Where v is velocity and f is frequency.

To determine the wavelength of the wave, we substitute our given values into the expression above.

[tex]\lambda = \frac{v}{f} \\\\\lambda = \frac{600m/s}{200s^{-1}} \\\\\lambda = \frac{600ms/s}{200}\\\\\lambda = 3m[/tex]

Therefore,  the wavelength of the wave traveling at the given velocity and frequency is 3m.

The kinetic energy will be "0.5 J". To understand the calculation, check below.

According to the question,

Mass or object, m = 10 N or,

                               = 1 kg

Speed, v = 1 m/s

We know the formula,

→ Kinetic energy, K.E = [tex]\frac{1}{2}[/tex] mv²

By substituting the values, we get

                                    = [tex]\frac{1}{2}[/tex] × 1 × (1)²

                                    = [tex]\frac{1}{2}[/tex] × 1 × 1

                                    = [tex]\frac{1}{2}[/tex]

Taking into account the definition of permutation, there are 1320 ways you can listen to 3 songs from a cd that has 12 selections.

Permutations 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.

The 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:

and 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

Finally, there are 1320 ways you can listen to 3 songs from a cd that has 12 selections.
