Velocity is the speed of an object moving in a definite direction. The velocity of an object can be uniform or variable. When an object moving along a straight line at variable speed, we can Express the magnitude of its rate of motion in terms of average velocity.
Average velocity=Initial velocity+Final velocity/2
The SI unit of velocity is m/s.
The sun contains about 99.9 percent of the mass of the solar system.
Answer:
Yes.
Explanation:
The processes that formed the small stream bed are similar to those that formed the Grand Canyon because both are formed by the flowing of river. The river flow through these regions and with this flow they takes rock particles with itself and makes several shapes and structures of that region. So we say that rivers and streams are responsible for the formation of stream bed and Grand Canyon.
Answer:
Aside from using complex carbohydrates to create the plant's structure, plants store carbohydrates or use them for energy to grow. To use stored carbohydrates, plants take the glucose formed during photosynthesis and combine the carbohydrate with oxygen -- a process called respiration -- to release energy.
Answer:
Solution A has the greater concentration of hydronium ions. That solution is 100 times more concentrated than the other solution.
Explanation:
For solution A take 10^-pH in this case 10^-2=.01
For solution B you would take 10^-4=.0001
.01>.0001 so solution A is more concentrated with H^+
To figure out how much more concentrated one solution is than the other:
(10^-2)/(10^-4)
