Consider two identical iron nails: one nail is heated to 95 °c, the other is cooled to 15 °c. the two nails are placed in a coffee cup calorimeter and the system is allowed to come to thermal equilibrium. what is the final temperature of the two nails
In this case, the final temperature of the two nails will be an average of their initial temperatures, which is 55 °C.
Explanation:When two objects at different temperatures come into contact, heat is transferred from the object with higher temperature to the object with lower temperature until they reach thermal equilibrium.
In this case, the heated iron nail at 95 °C will transfer heat to the cooled iron nail at 15 °C when they are placed in the coffee cup calorimeter.
The final temperature of the two nails will be an average of their initial temperatures, which is (95 °C + 15 °C) / 2 = 55 °C.
What is the equation of the line in standard form? (-3, 1) (3, 2)
Final answer:
The equation of the line passing through the points (-3, 1) and (3, 2) in standard form is (1/6)x - y = 5/6.
Explanation:
The equation of a line in standard form is Ax + By = C, where A, B, and C are constants. To find the equation of the line passing through the points (-3, 1) and (3, 2), we need to find the values of A, B, and C.
To do this, we can use the slope-intercept form of a line, y = mx + b, where m is the slope and b is the y-intercept. First, let's find the slope using the formula:
m = (y2 - y1) / (x2 - x1)
Plugging in the values, we get:
m = (2 - 1) / (3 - (-3)) = 1/6
Now, we can substitute the slope (m) and one of the given points (x, y) into the slope-intercept form to find the y-intercept (b). Using (-3, 1) as the point:
1 = (1/6)(-3) + b
Simplifying, we get:
b = 5/6
Now, we can substitute the values of m and b into the standard form equation to get:
(1/6)x - y = 5/6

If the length between points on a map is 6 inches, 8 inches, and 9 inches, and the scale is one inch equals 5 miles, find the distances in miles.
a.) 1.2, 1.6, and 1.8 miles
b.) 11, 13, and 14 miles
c.) 30, 40 and 45 miles
Answer:
Option c is correct
Distance in miles are; 30, 40, 45 miles
Step-by-step explanation:
As per the statement:
If the length between points on a map is 6 inches, 8 inches, and 9 inches.
It is also given that:
1 in. = 5 miles
We have to find the distance in miles:
For 6 inches.
1 in. = 5 miles
6 in. = [tex]6 \cdot 5 = 30[/tex] miles
Similarly, for 8 inches:
8 inches = [tex]8 \cdot 5 = 40[/tex] miles
For 9 inches:
9 inches = [tex]9 \cdot 5 = 45[/tex] miles
Therefore, distance in miles are; 30, 40, 45 miles

A rumour spreads exponentially through a college. 100 people have heard it by noon, and 200 by 1 p.m. How many people have heard it (a) by 3 p.m., (b) by 12.30 p.m., (c) by 1.45 p.rn.?
a) people have heard it by 3 p.m is 800 people
b) people have heard it by 12.30 p.m is 141 people
c) people have heard it by 1.45 p.m is 530 people
Let's analyze this rumor spread problem. Each person who hears the rumor is assumed to spread it to exactly two other people.
a) By 3 p.m.: The rumor spreads for 3 hours after noon. Starting with 100 people at noon, by 3 p.m. it would be 100 * 2^3 = 100 * 8 = 800 people.
b) By 12:30 p.m.: The rumor spreads for half an hour after noon. That's 30 minutes or 0.5 hours. Since the rumor spreads exponentially, in half an hour, the number of people who hear it doubles once. So, by 12:30 p.m., it would be 100 * 2^0.5 = 100 * √2 ≈ 100 * 1.41 ≈ 141 people.
c) By 1:45 p.m.: The rumor spreads for 1 hour and 45 minutes after noon, which is 1.75 hours. So, by 1:45 p.m., it would be 100 * 2^1.75 ≈ 100 * 5.3 ≈ 530 people.
In summary:
a) 800 people
b) 141 people
c) 530 people

A jar holds 128 fluid ounces of juice. The label says the jar has 16 servings. How many fluid ounces are needed for 80 servings?
Answer: 640 fluid ounces
Step-by-step explanation:
We assume that the fluid ounces in jar is directly proportional to the number of servings.
Given : A jar holds 128 fluid ounces of juice. The label says the jar has 16 servings.
Ratio of fluid ounces of juice to number of servings =[tex]\dfrac{128}{16}[/tex] (1)
Let x denotes the fluid ounces are needed for 80 servings.
Ratio of fluid ounces of juice to number of servings =[tex]\dfrac{x}{80}[/tex] (2)
From (1) and (2) , we have
[tex]\dfrac{x}{80}=\dfrac{128}{16}[/tex] [in direct variation ration remains constant.]
[tex]x=\dfrac{128\times80}{16}=640[/tex]
Hence, 640 fluid ounces are needed for 80 servings.

This question is all about doubles. The given bottom cards 5
2 3 4 and the top cards are 1 4 3 2.
The problem is asking to match the top cards to the bottom ones then adding 1
to get the doubles.
So 1 should be corresponding to two. Since 1 + 1 = 2
4 should be corresponding to 5. Since 4 + 1 = 5
3 should be corresponding to 4. Since 3 + 1 = 4
And lastly, 2 should be corresponding to 3. Since 2 + 1 = 3

the difference of a given month's rainfall from the average monthly rainfall is called the deviation. What is the deviation for each month shown?
average monthly rainfall 3.6
given month may 2 3/5; june 7/8; July 4 1/4
Answer:
Deviation:
may : 1
june: 0.875
july: 0.65
Step-by-step explanation:
It's given that the difference of a given month's rainfall from the average monthly rainfall is called the deviation .
To find : deviation for each month: may 2 3/5; june 7/8; July 4 1/4:
Solution :
Average monthly rainfall = 3.6
Rainfall in may = [tex]2\frac{3}{5}[/tex] = 2.6
Deviation = Average monthly rainfall - month's rainfall ( may ) = 3.6 - 2.6 = 1
Rainfall in june = 3.6 - 0.875 = [tex]\frac{7}{8}=2.725[/tex]
Deviation = Average monthly rainfall - month's rainfall ( june ) = 0.875
Rainfall in july = [tex]4\tfrac{1}{4}=\frac{17}{4}=4.25[/tex]
Deviation = Average monthly rainfall - month's rainfall ( july ) = 4.25 - 3.6 = 0.65
