The intensity of a sound describes <em>its loudness at a particular distance</em><em />
Sound intensity is factored by the ear's sensitivity to the particular frequencies contained in a sound
Sound loudness describes the strength of the ear's perception of a sound.
These two points being said, if the ear is more sensitive to a frequency, that sound will be louder to us than sounds at different frequencies that might not be as sensitive to our ears. <em>So, the more intense the sound, the louder it is ;)</em>
Thank you for your question! I hope this helped! Have an amazing day! :D
Answer:
10g Carbon has more particles.
Explanation:
To Find
Which has more particles 10g of C or 10g of Ca
The molar mass of carbon is 12g and Calcium is 40g.
1 mole of atom , molecule or ions contain Avagadro number (6.022×10∧23) of particles and also have a mass equal to it's molar mass.
For C,
12g C will have 6.022×10∧23 atoms
10g C will have 
×6.022×10∧23 atoms
=0.833 × 10∧23 atoms
For Ca,
1 mole Ca =40g
40g Ca will have 6.022×10∧23 atoms
10g Ca will have 
×6.022×10∧23 atoms
=0.25 × 6.022×10∧23 atoms
Since the half life of the radioactive isotope is 4,000 years, after 4,000 years the amount of the isotope would decrease by half. (Hence the name, half life.) So, after 4,000 years, there would be half of the isotope left in the fossil.
Answer:
When you have many birds for one and they eat these berries (All Berries have seeds) then you have these birds dropping their feces all over the country and others Then that spreads these plants and berries to new places.
Explanation:
This is also known as Seed Dispersal.

Answer:
For the tetrahedral case the repulsion is smaller.
Explanation:
It is smaller for the tetrahedral case because he angles for tetrahedral molecules are greater (109.5) then for octahedral molecules (90). The greater the distance between the atoms the smaller the repulsion, and so the bigger are angles the bigger is distance.
