Answer:
metric dimensions, i think
Explanation:
Answer: False
Explanation:
Winds are named for the cardinal direction they blow from. Hence, a wind that <em>"blows towards the east"</em>, logically should <u>come from the west </u>and is called a <em>"west wind"</em>.
In thise sense, one of the best examples of this type of wind are the <em>Westerlies</em>, which are are prevailing winds that blow from the west at midlatitudes and have the characteristic that are stronger during winter and weaker during summer.
Therefore, the statement is false.
Answer: I believe it’s .25 m/s
Explanation: the speed is measured distance/ time. Which is .5 meters/ 2 seconds =0.25
Answer:
By the use of the reaction force one body is able to accelerate because it is not fixed to a rigid support which offers a materialistic resistance.
Explanation:
For every force there is an equal and opposite reaction is stated in the Newton's third law of motion holds true universally.
This law accounts for the acceleration of the bodies with respect to the object that applies force on the other body. The acceleration is possible when iether one of the body is fixed and cannot move or when that both the bodies are not fixed can move.
- For example consider a rocket with its engine started. This rocket generates upthrust by conversion of chemical energy of the fuel into the mechanical energy applying force on the launchpad. When this force is large enough it to lift the rocket then the rocket starts moving in the air and it accelerates. Now, when it is in the air or in vacuum during the course of its journey it uses the reaction of the burnt gases of the fuel to change the momentum.
This is in accordance with the Newton's second law of motion, stating that the Force is directly proportional to the rate of change in momentum.
Answer: Water is absorbed in the intestine through gradient transport. The correct option is E.
Explanation:
Absorption of water in the mammalian intestines occurs largely on the small intestine through a transport mechanism known as osmosis. Osmosis is the movement of water molecules, through a semi permeable membrane, from the region of lower solute concentration into higher solute concentration to attain an equilibrium.
For water molecules to be absorbed from the lumen into the bloodstream, it's dependent on sodium absorption. This follows the following steps:
-sodium is absorbed by co transport with glucose and amino acids.this aids to move sodium from lumen into the enterocyte.
- Rapid exportation of absorbed sodium through sodium pimps from the enterocyte.
- As sodium is pumped out of cells an osmotic gradient is formed across apical cell membrane, this helps to osmotically drive water across the epithelium. Therefore water is absorbed in the intestine through the osmotic gradient created by sodium absorption. I hope this helps. Thanks.
