Answer;
Open system; can exchange both matter and energy; An example is a living organism such as human being, we actively interact with environment, which results in changes to both the environment and human being, for instance we eat to acquire energy.
Closed system; can exchange energy but not matter; An example is a saucepan, t<span>he saucepan allows energy transfer as the saucepan heats up and heats the contents inside it, putting a lid on it, prevents matter from entering and becomes a closed system.</span>
Isolated system; Can exchange neither energy nor matter. For example is a thermos. if tea is poured into a thermos or an insulated container there is no exchange of heat or matter.
Explanation:
What are the three waves of an earthquake? Fastet to Slowest
ANS: An earthquake generates three kinds of waves: surface waves (L waves), which are the slowest and weakest; shear (S) waves, which are transverse waves and carry most of the energy; and pressure (P) waves, which are longitudinal waves and travel the fastest. The speed of P waves is approximately 7.0 km/s, and that of S waves is about 4.0 km/s.
This is the Answer for this question :3
I hope you are having a great day :3
Light speed in water is 2.25 times 10^5 m/s so the index of refraction is higher than the index of refraction of light in a vacuum which is 1.0. (speed in vacuum for light is 300,000 km/s)
Index of refraction of light in water is 3.0 time 10^5 m/s divided by 2.25 times 10^5 m/s = 1.33.
Hope this is what you wanted.
