A chart labeled table B: effect of mass on temperature with initial temperature as 25 degrees Celsius, mass w is 1.0 kilograms and h is 500 m. The chart is 5 columns and 5 rows. The first column is labeled mass c in kilograms with entries 1.0, 3.0, 6.0, 9.0. The second column is labeled temperature final in degrees celcius with entries 26.17, 28.52, 32.03, 35.55. The third column is labeled change in temperature in degrees celcius with entries 1.17, 3.52, 7.03, 10.55. The fourth column is labeled gravitational potential energy in kilojoules with no entries. The last column is labeled delta H in kilojoules with no entries. Use the data provided to calculate the gravitational potential energy of each cylinder mass. Round your answers to the nearest tenth. 3 kg: kJ 6 kg: kJ 9 kg: kJ
Answer:
3 kg= 14.7
6 kg= 29.4
9 kg= 44.1
Step-by-step explanation:
The gravitational potential energy of the cylinders as follows:
3 kg: 14.7 kJ, 6 kg: 29.4 kJ, and 9 kg: 44.1 kJ
What is the GPE?GPE is gravitational potential energy, mass is the mass of the object in kilograms, gravity is the acceleration due to gravity in meters per second squared (usually taken to be 9.8 m/s²), and height is the height of the object above the reference point in meters.
To calculate the gravitational potential energy (GPE) of an object, you need to know its mass, the acceleration due to gravity, and its height above a reference point. You can use the formula:
GPE = mass × gravity × height
In this case, the mass of each cylinder is given in the first column of the chart, and the height of the cylinders is 500 meters. However, the acceleration due to gravity is not given in the chart. We can assume that it is 9.8 m/s², but if you have a different value, you should use that instead.
Using these values, we can calculate the gravitational potential energy of the 3-kilogram cylinder as follows:
GPE = 3 kg × 9.8 m/s² × 500 m = 14700 kg m/s²
Converting this to kilojoules gives us:
GPE = 14700 kgm/s² × (1 J/1 kgm/s²) = 14700 J
Converting this to kilojoules (kJ) gives us:
GPE = 14700 J / 1000 J/kJ = 14.7 kJ
Therefore, the gravitational potential energy of the 3-kilogram cylinder is 14.7 kJ.
You can use the same process to calculate the gravitational potential energy of the 6-kilogram is 29.4 kJ and the 9-kilogram cylinders is 44.1 kJ.

LAST QUESTION AND HURRY IM BEING TIMED Last year, the enrollment at Highland Middle School was 800 students. This year, the enrollment dropped to 700 students due to the opening of a new middle school. Which best reflects the percent change in enrollment at Highland Middle School from last year to this year?
Answer:
-12.5
Step-by-step explanation:
Gemma earns $575 a week plus $180 commission for each car she sells. She earned
$1835 last week. How many cars did she sell?
O She sold 6 cars.
O She sold 7 cars.
O She sold 8 cars.
O She sold 9 cars.
Answer:
7 cars
Step-by-step explanation:
Gemma earns $575 a week plus $180 in commission for each car sold
She earned $1835 last week
Therefore the amount of cars sold can be calculated as follows
= $575 + $180(7)
= $575 + $1260
= $1835
Hence 7 cars were sold

What are additive and multiplicative inverses?A number's additive inverse is a number that is added to it until the result is zero.
A number multiplied by another such that the result is 1 is the multiplicative inverse of that number.
A number added to it's additive inverse results to zero.
From the given options the only options that satisfies the result to be zero
are,
- 52 + 52.

Solve for g. If you can please add an explanation
Answer:
g=7
Step-by-step explanation:
your goal is to isolate the g
times g/-4 by -4/1 the -4 cancels out the other one so you are just left with g
move the g to the other side of the equation then move the 3 and it to the -5 and then multiply the whole thing but -1 to make the equation positive

Answer:
Keaton solved it right.
Step-by-step explanation:
Both students did the first step correctly, but Emily divided on the last step instead of multiplying. When there is a division on the other side of the equation, you would have to multiply the denominator on both sides. Keaton correctly multiplied the denominator of 3 on each side which gives 12 * 3 = 36.
I really hope this helps! :)
Answer:
Keaton is correct.
Step-by-step explanation:
w/3 + (-2) = 10
+2 +2
w/3 = 12
multiple 3 on both sides to get rid of the fraction bc fraction means division
w = 36

If you add all the numbers up you get -2.23 which would be a loss
Answer:
The company shows loss
Step-by-step explanation:
32.65 - 75.32= -42.67 so they're already at a loss
you would add -125.75 and -42.67 and woud get -168.42
Then you would add 100.89 and 65.30 and you would get 166.19
166.19+(-168.42)=-2.23

4x + 6y = -4
4x + 3y = 2
ASAP
Answer:
(2,-2)
Step-by-step explanation:
-1(4x + 6y = -4)
4x + 3y = 2
-4x - 6y = 4
4x + 3y = 2
-3y=6
divide it by -3 to get y.
y=-2
4x + 3(-2) = 2
4x - 6 = 2
add 6 to both sides.
4x = 8
divide by 4 to get x.
x=2
