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.

The ratio of the amount of vitamin A in cow milk to the amount of vitamin A in goat milk is

miv72 [106K]

Answer:

2080 IU

Explanation:

Given

Ratio of vitamin A in cow milk to goat milk = 3 : 4

Required

Determine the content of vitamin A in goat milk if cow milk has 1560 IU

The given parameters shows a direct proportion.

Let G represents Goat and C represent Cow

Given that there exists a direct proportion;

C = K * G where K represents the constant of proportionality.

Solving for K when C = 3 and G = 4

C = K * G becomes

3 = K * 4

3 = 4K

Divide through by 4

¾ = K

K = ¾

Now, solving for G given that C = 1560IU;

We'll make use of the same formula as above

C = K * G

Substitute 1560 for C and ¾ for K; the expression becomes

1560 = ¾ * G

Multiply both sides by 4

4 * 1560 = 4 * ¾ * G

6240 = 3 * G

Multiply both sides by ⅓

⅓ * 6240 = ⅓ * 3 * G

2080 = G

G = 2080

Hence, the vitamin A in the goat milk is 2080IU
