Arunner is traveling around the track below at a constant speed. is she accelerating? a. yes, she is accelerating because her speed is constant. b. yes, she is accelerating as she turns and changes direction. c. no, she is not accelerating because there is not an incline to the track. d. no, she is not accelerating because her speed is constant.

ANSWER:

D.No, she is not accelerating because her speed is constant.

EXPLANATION:

The rate of change of velocity with respect to time is known as acceleration.

acceleration =change in velocity/time

As she is running at constant speed  and there is no change in velocity so she is not accelerating.

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
