Newton’s law of cooling states that for a cooling substance with initial temperature t0, the temperature t(t) after t minutes ca

antoniya [11.8K]

The cooling rate of the substance is approximately 0.0732.

According to the statement, the Newton's law of cooling is defined by the following formula:

$T(t) = T_{s} + (T_{o}-T_{s})\cdot e^{-k\cdot t}$ (1)

Where:

$T_{s}$ - Final temperature, in degrees Celsius.
$T_{o}$ - Initial temperature, in degrees Celsius.
$t$ - Time, in minutes.
$k$ - Cooling rate, in $\frac{1}{min}$ .
$T(t)$ - Current temperature, in degrees Celsius.

Please notice that substance reaches thermal equilibrium when $T(t) = T_{s}$ , that is when temperature of the substance is equal to the temperature of surrounding air.

If we know that $T_{o} = 80\,^{\circ}C$ , $t = 15\,min$ , $T_{s} = 50\,^{\circ}C$ and $T(15) = 60\,^{\circ}C$ , then the cooling rate of the substance is:

$60 = 50 + (80 - 50)\cdot e^{-15\cdot k}$

$\frac{60-50}{80-50}= e^{-15\cdot k}$

$\frac{1}{3} = e^{-15\cdot k}$

$k = -\frac{1}{15}\cdot \ln \frac{1}{3}$

$k \approx 0.0732$

The cooling rate of the substance is approximately 0.0732.

S21: sorting algorithms bubble sort for each set of data, write out each pass of bubble sort. 1. sort in descending order, begin

sattari [20]

The sorted algorithm of the bubble sort in descending order, beginning at the front is:

56, 23, 10, 7, 15, 11, 4, 1

56, 23, 10, 15, 11, 7, 4, 1

56, 23, 15, 11, 10, 7, 4, 1

<h3>What is Sorting Algorithm?</h3>

This refers to the type of algorithm that is used to rearrange a given array or list elements according to a comparison operator on the elements.

Therefore, we can see that based on the bubble sort: 56, 1, 23, 10, 7, 15, 11, the correct sort in the descending order, beginning at the front is given above.
