Answer:
Electromagnetic propagation through water is very different from propagation through air because of water's high permittivity and electrical conductivity. Plane wave attenuation is high compared to air, and increases rapidly with frequency.
And the results show that the effect of sand with electric charges all over its surface on electromagnetic wave attenuation is the same as that of sand without charge, which proves that electric charges distribute on partial surface of the sand in fact.

DIRECTIONS: Use the formula below and show your work with you answer
A=∏r2
Answer:
0.79
Explanation:
Using the formula it would be ----
A = πr^2
= π × 0.5^2 ≈ 0.7854
= π × 0.25 ≈ 0.7854
0.7854 rounded to the nearest hundredth would be 0.79

How do the types and numbers of atoms that repeat to make up a substance affect its properties?
Answer:
Chemical formula determines chemical structure and the properties of a substance.
Explanation:
The chemical formula of a substance depicts what atoms are in the substance, how many times they reoccur and in what ratio. Chemical formulas could be in form of: empirical, molecular or structural formula.
All of these determine the property of the substance, for instance in isomers of a compound.

There are _____ major plates that make up the most of the continents and the Atlantic and Pacific Ocean.
A)5
B) 12
C) 8
D) 7
Answer and Explanation:
D) 7 is the answer
Together, the crust and the upper part of the mantle form the lithosphere, Earth's solid outer shell. This rocky, brittle layer is broken up into seven major and several minor tectonic plates (also known as lithospheric plates) that fit together like puzzle pieces.
#teamtrees #PAW (Plant And Water)
The number of major plates that make up the most of the continents and the Atlantic and Pacific Ocean are seven.
What are major plates?When the upper solid shell part of the earth is break down then they will form major plates.
The major plates that are present on the earth are the African, Antarctic, Eurasian, North American, South American, India-Australian, and the Pacific plates.
Hence option (3) is correct i.e. 7.

I need help.... How does the kinetic energy of molecules explain both Boyle’s and Charles’ Laws?
Answer:
Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic Molecular Theory can be used to explain both Charles' and Boyle's Laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only. Hope this helps!!

Title of your comic strip: The journey of Baia
Baia is a abnormal creature who crashed down on earth a hour ago. She is made up of 95% water and 5% carbon! While Baia explores Earth, she accidentally went past a super hot black metal. Since she is almost all water, conduction happens as she starts to began to steam. She quickly notices this and immediately run inside a waterproof box that was near by. Since she was so hot, she turned into water. Soon she was just a water on the floor but than the room became hot. It was so hot! She soon realizes that she is in a steam room. Within a hour span, her whole body became steam/gas! Just than, a man walks in and the doors sucks her outside to become the cloud. How interesting she thought!
(You could use this story but my device won't let me upload the photo so pretty much draw a meteor crashing down on earth. Next draw a blue shaped item (could be squared) and show it move next to a steaming black metal) After that make it inside a box. Next, draw a puddle of water. Later draw some steam (swigglely line vertical) to indicate her being steam. Last, draw some clouds!!!
