Answer:
Northern states were more against slavery while the south was more pro-slavery because they felt that they needed slaves to, manage farms and plantations growing indigo, rice and tobacco. The south was very dependent on plantations and slaves while the north was dependent on factories. Later in history the 13th amendment was passed, this was supposed to officially end slavery, to get around this people in the south created "Black Codes" or "Jim Crow Laws" which were made to limit African American freedom. Discrimination still occurred in northern states but was less harsh than it was in the south. This is partially due to the black minority in northern states. I really hope this helps...
Explanation:
Goes down as the temperature decreases, and vice versa. Sound's frequency is independent of temperature, while its speed is directly proportional to temperature. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly. ... This is faster than 331 meters per second, which is the speed of sound in air at freezing temperatures.
