Answer:
3.) 463 J/g
Explanation:
Heat given by the fuel is used to increase the temperature of the water
so it is given as
![Q = ms\Delta T](https://tex.z-dn.net/?f=Q%20%3D%20ms%5CDelta%20T)
here we will have
m = 250 g
![\Delta T = 26.55 - 25](https://tex.z-dn.net/?f=%5CDelta%20T%20%3D%2026.55%20-%2025)
now we also know that
![s = 4186](https://tex.z-dn.net/?f=s%20%3D%204186)
so we have
![Q = (0.250)(4186)(26.55 - 25)](https://tex.z-dn.net/?f=Q%20%3D%20%280.250%29%284186%29%2826.55%20-%2025%29)
![Q = 1622.075 J](https://tex.z-dn.net/?f=Q%20%3D%201622.075%20J)
so 3.5 g fuel gives above energy
so per gram of fuel will have total energy given as
![Q = \frac{1622.075}{3.5}](https://tex.z-dn.net/?f=Q%20%3D%20%5Cfrac%7B1622.075%7D%7B3.5%7D)
![Q = 463.45 J/g](https://tex.z-dn.net/?f=Q%20%3D%20463.45%20J%2Fg)
The answer is GAS. In a gas, the particles are in a completely random motion in any direction. And it is not solid. Hope I helped. Good luck

Hello! My name is Zalgo and I am here to help you out on this concluding day. The answer would be C);lower. The reason it would be lower is because the hottest color of flames would be blue. Considering the way a start emits light is fire, this would be the most logical reason for it.
I hope that this helps! :P

Answer: C
Frictional force
Explanation:
The description of the question above is an example of a circular motion.
For a car travelling in a curved path, the frictional force between the tyres and the road surface will provide the centripetal force.
Since the road is banked, and the cross section of the banked road is constructed like a ramp. The car drives transversely to the slope of the ramp, so that the wheels of one side of the car are lower than the wheels on the other side of the car, for cornering the banked road, the car will not rely only on the frictional force.
Therefore, the correct answer is option C - the frictional force.
