Physics! 1. was the object at rest during the time interval labeled "b"? yes no 2. was the object accelerating during the time interval labeled "b"? yes no

Q1: No

Q2: No

Explanation:

the slope of velocity time graph gives the value of acceleration.

In section B

the graph is parallel to X axis, it means it is moving with constant velocity. Here the slope of graph in section B is zero.

Q1: Object is moving with constant velocity

Q2: The acceleration is zero

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
