A car is stopped at a stop light. When the light turns green, it travels south 55 m/s in 5s. What is its acceleration? *

11m/s^2

Explanation:

Acceleration can be calculated by diving speed by time. Since we know speed and time, acceleration can be calculated.

55/5 = 11m/s^2

the rearrangement of particles in a physical change. hope this

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
