Newton’s law of cooling states that for a cooling substance with initial temperature t0, the temperature t(t) after t minutes can be modeled by the equation t(t)=ts+(t0−ts)e−kt, where ts is the surrounding temperature and k is the substance’s cooling rate. A liquid substance is heated to 80°c. Upon being removed from the heat, it cools to 60°c in 15 min. What is the substance’s cooling rate when the surrounding air temperature is 50°c? round the answer to four decimal places. 0. 0687 0. 0732 0. 0813 0. 872.
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:
[tex]T(t) = T_{s} + (T_{o}-T_{s})\cdot e^{-k\cdot t}[/tex] (1)
Where:
[tex]T_{s}[/tex] - Final temperature, in degrees Celsius.[tex]T_{o}[/tex] - Initial temperature, in degrees Celsius.[tex]t[/tex] - Time, in minutes.[tex]k[/tex] - Cooling rate, in [tex]\frac{1}{min}[/tex].[tex]T(t)[/tex] - Current temperature, in degrees Celsius.Please notice that substance reaches thermal equilibrium when [tex]T(t) = T_{s}[/tex], that is when temperature of the substance is equal to the temperature of surrounding air.
If we know that [tex]T_{o} = 80\,^{\circ}C[/tex], [tex]t = 15\,min[/tex], [tex]T_{s} = 50\,^{\circ}C[/tex] and [tex]T(15) = 60\,^{\circ}C[/tex], then the cooling rate of the substance is:
[tex]60 = 50 + (80 - 50)\cdot e^{-15\cdot k}[/tex]
[tex]\frac{60-50}{80-50}= e^{-15\cdot k}[/tex]
[tex]\frac{1}{3} = e^{-15\cdot k}[/tex]
[tex]k = -\frac{1}{15}\cdot \ln \frac{1}{3}[/tex]
[tex]k \approx 0.0732[/tex]
The cooling rate of the substance is approximately 0.0732.

Explanation:
Which sentence from Mark Twain's essay "Advice to Youth" conveys Twain's opinion about why one’s youth is the right time to learn good values?
Being told I would be expected to talk here, I inquired what sort of talk I ought to make. They said it should be something suitable to youth--something didactic, instructive, or something in the nature of good advice. Very well. I have a few things in my mind which I have often longed to say for the instruction of the young; for it is in one’s tender early years that such things will best take root and be most enduring and most valuable. First, then. I will say to you my young friends--and I say it beseechingly, urgingly-- Always obey your parents, when they are present. This is the best policy in the long run, because if you don't, they will make you. Most parents think they know better than you do, and you can generally make more by humoring that superstition than you can by acting on your own better judgment.
Be respectful to your superiors, if you have any, also to strangers, and sometimes to others. If a person offend you, and you are in doubt as to whether it was intentional or not, do not resort to extreme measures; simply watch your chance and hit him with a brick. That will be sufficient. If you shall find that he had not intended any offense, come out frankly and confess yourself in the wrong when you struck him; acknowledge it like a man and say you didn't mean to. Yes, always avoid violence; in this age of charity and kindliness, the time has gone by for such things. Leave dynamite to the low and unrefined.
Answer:
I have a few things in my mind which I have often longed to say for the instruction of the young; for it is in one’s tender early years that such things will best take root and be most enduring and most valuable.
Explanation:
In this sentence, Twain explains why he believes that youth is a good time to learn moral values. After explaining that he has some things to say to children, he argues that it is during these years that such moral knowledge starts to take root in a person. He also believes that the things we learn during these years are the most enduring and most valuable in our future lives.

Which shows the correct values for the variables in the table? a = 18, b = 34, c = 65 a = 34, b = 18, c = 68 a = 34, b = 68, c = 47 a = 47, b = 18, c = 68.
The values of a, b, and c from the table are 34, 18, and 68 respectively.
From the given table, the following equations are true;
number of subscribers above $25000 + number of those not subscribing above $25000 = 47Set theorySubstituting the values:
a + 13 = 47
a = 47 - 13
a = 34
Similarly;
b + 55 = 73
b = 73 - 55
b = 18
Also, c = 13 + 55
c = 68
Hence the values of a, b, and c from the table are 34, 18, and 68 respectively.

Marian traveled at an average speed of 65 mi/h for 15 hours. Kristen travels at an average speed of 50 mi/h. How many hours does it take kristen to travel the same distance marian traveled? express your answer as a decimal to the nearest tenth.
The hours it takes Kristen to travel the same distance Marian travelled is 19.5 hours.
The average speed of Marian is 65 miles per hour for 15 hours. Therefore, her distance travelled can be calculated as follows:
speed = distance / time
Therefore,
distance = time × speed
distance = 15 × 65
distance = 975 miles
Kristen travelled at an average speed of 50 miles per hour. Kristen covers the same distance with Marian. Therefore, the hours it takes Kristen to travel the same distance Marian travelled can be calculated as follows:
speed = distance / time
time = distance / speed
time = 975 / 50

If differential heating did not occur on earth, which scenario would become true?.
There are different reasons why things happens. If differential heating did not occur on earth, then there no global warming or global cooling will take place in the atmosphere.
When the Earth flat surface is facing the sun, all its part of that surface would get the same level of incoming solar radiation but the fact remains that due to the Earth being spherical in shape, sunlight is therefore not distributed evenly over the Earth’s surface and as such all the regions of Earth will be heated to different degrees.
