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.
Answer:
Plants absorb water in a large amount because water is the only medium which is present in a plant for the transportation of minerals. So, the plant absorbs a lot of water even if it is lose by transpiration.
Explanation:
<span>The answer to your question is that all of the energy is ultimately radiated into empty outer space as heat. The second law of thermodynamics mandates that all processes that involve the transfer of energy MUST radiate a portion of this energy into space as waste heat. This is why when you run down the street you get hot and sweaty, and this is why automobiles MUST have a functioning radiator and nuclear power stations MUST have evaporation cooling towers or else be located near a large body of water to exchange excess waste heat into, etc., etc. It is also true that the transfer of energy at each step up the food chain is very inefficient. They say it takes around 50 lbs of corn to produce one pound of beef, and it probably takes 20-30 pounds of beef to produce one pound of human tissue. The rest of the energy just goes into your living room as radiated body heat. I hope this helps.</span>
Answer:
The independent variable is allowed to change and the dependent variable is held constant to see what other conditions
Explanation:
the dependent variable is what is being tested therefore it is what remains constant unlike the independent variable.
Hope this helps. let me know if im wrong.
Answer:
Precipitation, Surface Runoff and Infiltration process
Explanation:
There different stages of the water cycle where the water comes back on earth due to the gravitational force are as follows-
Rainfall/Precipitation- The water vapour in the cloud undergoes the process of condensation, it leads to the occurrence of rainfall, where the water comes freely over the ground surface from a certain height.
Surface Runoff- These refer to the flow of water rapidly along a steep slope, under the influence of gravity that eventually adds to the streams, lakes and rivers.
Infiltration process- This is the process where the water from the earth's surface percolates through the rocks and flows downward and eventually mixes with the groundwater.
