It would have to be c because it is a chemical change. your welcome!!!!!
Answer:
Hz
Explanation:
We know that
1 cm = 0.01 m
= Length of the human ear canal = 2.5 cm = 0.025 m
= Speed of sound = 340 ms⁻¹
= First resonant frequency
The human ear canal behaves as a closed pipe and for a closed pipe, nth resonant frequency is given as
for first resonant frequency, we have n = 1
Inserting the values
Hz
Answer:
Combination or synthesis
Explanation:
The reaction is a combination or synthesis reaction in which two or more substances combines to give a single product.
In such a reaction there is formation of compounds from the union of their constituent elements.
The driving force for such reactions is the large and negative heat of formation of the product.
So, this is a combination reaction.
There is more wire to travel through,farther distance, and a higher possibility of other disruptions. Please Mark Brainliest!!!
