Answer:
0.1132 kJ/K the total heat capacity of the calorimeter.
Explanation:
The combustion energy of glucose = 15.57 kJ/g.
Energy released on 2 combustion of 2.000 g of glucose = Q
![Q= 15.57 kJ/g\times 2.000 g=31.140 kJ](https://tex.z-dn.net/?f=Q%3D%2015.57%20kJ%2Fg%5Ctimes%202.000%20g%3D31.140%20kJ)
Q=31.140 kJ
Heat gained by the calorimeter = Q'
Heat gained by the calorimeter = heat released on combustion of glucose
Q'= 31.140 kJ
Temperature change of the calorimeter = ΔT = 23.34°C - 21.45°C = 1.89°C
ΔT = 1.89°C = 275.04 K
Total heat capacity of the calorimeter = C
![Q'=C\times \Delta T](https://tex.z-dn.net/?f=Q%27%3DC%5Ctimes%20%5CDelta%20T)
![C=\frac{Q'}{\Delta T}=\frac{31.140 kJ }{275.04 K}=0.1132 kJ/K](https://tex.z-dn.net/?f=C%3D%5Cfrac%7BQ%27%7D%7B%5CDelta%20T%7D%3D%5Cfrac%7B31.140%20kJ%20%7D%7B275.04%20K%7D%3D0.1132%20kJ%2FK)
0.1132 kJ/K the total heat capacity of the calorimeter.
Gabriella is speeding up at the same rate that Kendall is slowing down, and Franklin is not accelera
Answer:
The net gravitational force exerted by these objects is ![5.712\times10^{-8}\ N](https://tex.z-dn.net/?f=5.712%5Ctimes10%5E%7B-8%7D%5C%20N)
Explanation:
Given that,
Mass of another object m = 33.0 kg
Mass M₁ = 160 kg
Mass M₂ = 460 kg
Distance = 3.40 m
We need to calculate the net gravitational force
Using formula,
![F=\dfrac{GM_{2}m}{r^2}-\dfrac{GM_{1}m}{r^2}](https://tex.z-dn.net/?f=F%3D%5Cdfrac%7BGM_%7B2%7Dm%7D%7Br%5E2%7D-%5Cdfrac%7BGM_%7B1%7Dm%7D%7Br%5E2%7D)
![F=Gm(\dfrac{M_{2}-M_{1}}{r^2})](https://tex.z-dn.net/?f=F%3DGm%28%5Cdfrac%7BM_%7B2%7D-M_%7B1%7D%7D%7Br%5E2%7D%29)
Where, G = gravitational constant
m = mass of another object
= mass of first object
= mass of second object
r = distance
Put the value into the formula
![F=6.67\times10^{-11}\times33.0\times\dfrac{460-160}{(3.40)^2}](https://tex.z-dn.net/?f=F%3D6.67%5Ctimes10%5E%7B-11%7D%5Ctimes33.0%5Ctimes%5Cdfrac%7B460-160%7D%7B%283.40%29%5E2%7D)
![F=5.712\times10^{-8}\ N](https://tex.z-dn.net/?f=F%3D5.712%5Ctimes10%5E%7B-8%7D%5C%20N)
Hence, The net gravitational force exerted by these objects is ![5.712\times10^{-8}\ N](https://tex.z-dn.net/?f=5.712%5Ctimes10%5E%7B-8%7D%5C%20N)
All chemical processes are accompanied by energy changes. When a reaction proceeds, it either releases energy to, or absorbs energy from, its surroundings. In thermodynamics, these two types of reactions are classified as exothermic or endothermic, respectively.
Answer:
Funny answer but works!
Explanation:
Not enough air. Go outside, crack open the window and blow air into the room like you would a balloon then close the window quickly. If it doesn't start bouncing, try giving the house a push. Good luck.
