Answer:
what is the question? there isn't one
Heat is transferred when a substance changes phases. Substances can be made to change phases by fluctuating the temperature, the pressure, or both. I hope I could help!
Answer:
B. A car of mass 2000 kg with speed 7 m/s
Explanation:
The kinetic energy of an object is given by:

where m is the mass of the object and v is its speed.
From the formula, we see that the larger the mass and the speed of the object, the larger its kinetic energy. Among the choices given, we see that the car with largest mass and largest speed is car B, which has a mass of 2000 kg and speed of 7 m/s. Its kinetic energy is:

We can verify that the other cars have smaller kinetic energy. In fact:
- Car A: 
- Car C: 
- Car D: 
So, car B is the one which has most kinetic energy.
The answer
2y + 14 = 17
The 17 is to the right of the = sign
It is also the answer
