Answer:
For a longitudinal wave, such as a sound wave, amplitude is measured by the maximum displacement of a particle from its position of equilibrium. When the amplitude of a wave steadily decreases because its energy is being lost, it is said to be damped. So, a sound wave 's amplitude decreases as it moves through a medium.

Answer:
Einsteins theory about time says:
Time slows down or speeds up depending on how fast you move relative to something else (So when I'm having fun time move fast, and when I'm doing my homework, time moves slow :( )
Explanation:
Have a great summer :)
Answer:
Magnetic flux will be equal to
Explanation:
It is given radius of circular loop r = 0.10 m
Area of circular loop
Magnetic field B = 0.20 T
Angle between plane of loop and magnetic field
Magnetic flux will be equal to
So magnetic flux will be equal to
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.
