I'll put what is happening and I'll let you put it into your own words.
Point A is emitting a sound wave that travels down into the water and finds the ship (point B). The sound wave then bounces off the the ship and travels to a receiver that is located on the back of the ship (Point C). The ship then calculates the time from the emission of the wave to the reception of the wave and from there calculates the depth of the object.<span />
Answer: It represents the whole distance traveled. Hope this helps!
Explanation:
Answer:
1.97 * 10^8 m/s
Explanation:
Parameters given:
Refractive index, n = 1.523
Refractive index is the ratio of the speed of light in a vacuum to the speed of light in a specified medium.
When the medium is glass, the refractive index is given as:
n = Vv/Vg
Where Vv = velocity of light in a vacuum
Vg = velocity of light in glass
The velocity of light in a vacuum is 3 * 10^8 m/s. Therefore,
1.523 = (3 * 10^8)/Vg
Vg = (3 * 10^8)/1.523
Vg = 1.97 * 10^8 m/s
Answer:
Structural adaptation
Explanation:
When any physical body part of an organism helps it in surviving, then this mechanism of survival is called a structural adaptation. For example short tail of penguins helps them in balancing on their heels and tails due to which they are able to reduce heat released from their feet. Thus, any physical parts of an organism that helps them in coping with the surrounding physical environment /predators are refereed to as a mode of structural adaptation.
Energy stored= Li^2/2
Therefore L=2(E.S)/i^2
= 0.0013
