The answer is : Low frequency sounds
place theory is a theory of hearing which states that our perception of sound depends on where each component frequency produces vibrations along basilar membrane, which is very sensitive to low frequency sound
Answer:
0.05
Explanation:
Given a variable C which is the product of two variables A, B:
Then the absolute error on C is given by:
where are the uncertanties on the measure of A, B and C, respectively.
In this problem, the horizontal component of the velocity is given by
Therefore, the uncertainty on vx is given by:
(1)
where we have:
, so
The uncertainty on is given by:
where:
and
So
Also,
So, combininb everything into (1), we find:
Answer:
Explanation:
The length, of the string , fundamental frequency and the tension on the string are related as:
#Since both E and G have the same length and tension on them:
Where are the linear densities, the fundamental frequencies.
#taking square and inverse on both sides, we have:
Hence, the linear density of the G string is 0.00393kg/m
Answer:
ΔT = 1ºC
, 2ºCand 3ºC
Explanation:
In this exercise they indicate the specific heat of lithium
let's calculate the temperature increase as a function of the heat introduced
Q = m ΔT
ΔT = Q / m c_{e}
calculate
for Q = 3.5 J
ΔT = 3.5 / (1 3.5)
ΔT = 1ºC
For Q = 7.0 J
ΔT = 7 / (1 3.5)
ΔT = 2ºC
for Q = 10.5 J
ΔD = 10.5 / (1 3.5)
ΔT = 3ºC
we see that this is a straight line, see attached
