True
Explanation:
Average speed is a scalar magnitude as opposed to average velocity which is a vector. The unit of measurement in the International System (S.I.) of the average speed is the meter per second (m/s).
If the runner ends where she started, then her total displacement is 
, which means her average velocity will be
The total distance she traversed, however, was 
, which gives her an average speed of
I need to see the picture. It is either gravity or air resistance (friction)
Answer:
Absorbed sunlight is balanced by heat radiated from Earth's surface and atmosphere. ... The atmosphere radiates heat equivalent to 59 percent of incoming sunlight; the surface radiates only 12 percent. In other words, most solar heating happens at the surface, while most radiative cooling happens in the atmosphere
Rubber. The other three are metals, and therefore good conductors.
