We should describe a little bit the legend.
A - Element - we should have circles with same color and not bonded together (argon gas).
B - Compound - here we may have circles with same or different color bonded together (water or oxygen which is a diatomic molecule).
C - Mixture of elements - circles with different colors not not bonded together (mixture of noble gases).
D - Mixture of compounds - circles with same or different color bonded together but we should see two or more types of connectivity between circles (mixture of water and ethanol).
E - Mixture of elements and compounds - circles with same or different color bonded together mixed with circles with same color and not bonded together (a mixture between oxygen which is a diatomic molecule and noble gas like argon).
Now we may answer the question:
1) B
2) C
3) D
4) D
5) A
6) B
7) B
8) E
9) E
10) D
11) B
12) D
13) D
14) D
15) D
The body system that arterial wall belong to is blood vessels, i would say. And Fatty deposit belong to connective tissue i would say. Please, i tried my best to answer. if you dont understand please search more about it. :)
This statement is: False
Boiling is vaporization that occurs both below and at the surface of the liquid.
However, evaporation happens at the surface of the substance.
So, if you need to correct this statement, the correction would be:
Sublimation and evaporation happen at the surface of the substance.
Answer:
Speed of wave = 1500 m/s
Explanation:
Given data:
Frequency of wave = 10 Hz
Wavelength of wave = 150 m
Speed of wave = ?
Solution:
Formula:
Speed of wave = Frequency × Wavelength
Now we will put the values in formula.
Speed of wave = 10 Hz × 150 m
Speed of wave = 1500 m/s
Hz = s⁻¹
