Answer:
Sound quality
Explanation:
Loudness refers to the property of sound that depends on the amplitude of the sound wave while pitch is the property of sound that depends on the frequency of the sound wave.
Now, when sounds have the same pitch and loudness, it means they possess the same natural frequency and also, they will have similar resonance and standing waves. Despite all these similarities, the quality of these sounds will tend to vary from one to another.
Answer: 4 is the subscript in 
.
Explanation:
We know that,
Subscript: The number of atom present in a given compound.
In , 4 represents the number of chlorine atom in 1 mole of Silicon tetra chloride.
Coefficient: Number of atom which is used in reaction.
For example: In 
, 3 is the coefficient of silicon tetra chloride.
A Product : In the balance equation, right hand side is called product.
A reactant : In the balance equation, left hand side is called reactant.
For example: the balance equation is
In this equation, 
is the reactants and 
is products.
Hence, 4 is the subscript in .
Answer:
1.29 N
Explanation:
The equation for force (with work and distance) is:
We can plug in the given values into the equation:
There could be many different comparison features that would
lead to an observation of similarity or dis-similarity.
A mirror might be said to be similar to a convex lens if it is round,
or if it has a curved surface, or if it is made of glass.
