A. Coming out near the South Pole and going in near the North Pole
KE = ½mv² = ½(4.00 kg)(16.0 m/s)² = 512 J
The temperature rises until the water reaches the next change of state — boiling. As the particles move faster and faster, they begin to break the attractive forces between each otherand move freely as steam — a gas. The process by which a substance moves from the liquid state to the gaseousstate is called boiling.
Answer:
1 question is- I believe 4. Melting Question 2 is Density
Explanation:
THOUGHT ABOUT IT!!!
Friction is directly related to air particles.
When we say that friction is high, it means that you're colliding with lots of air particles, and hence you can't speed up as easily.
Thus, the more air particles you encounter, the higher the friction.
The faster you go, the more particles you will encounter in a given time; hence at higher speeds, the friction is higher.
