Answer:
C
Explanation:
The speed of a molecule is directly related to its kinetic energy, which is directly related to the temperature. As the temperature increases, so does a molecule's speed. Of the options provided, only option C has a higher speed than 500m/s.
Answer:
For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars. To qualify as a vector, a quantity having magnitude and direction must also obey certain rules of combination.
Explanation:
Work=mass×gravity due to acceleration ×height
Work=100×9.8×5
Work=4900J
"Traditionally, physical science courses are categorized into four areas: physics, chemistry, earth sciences, and space sciences. It is important to understand that the arbitrary divisions of specialized knowledge are integrated into a basic overview of the physical laws that govern our universe." - Cameron University
