Answer:
f = 4.67 Hz
Explanation:
We can approximate the wave as a traveling wave, therefore the speed of the wave is constant
v = d / t
the total distance remember, in going to the wall and back is
d = 2 11.2 = 22.4 me
we substitute
v = 22.4 / 4.0
v = 5.6 m / s
now we can use the relationship between the speed of the wave, its wavelength and u frequency
v =λ f
f = v /λ
f = 5.6 / 1.2
f = 4.67 Hz
Answer:
A.The new discovery might cause the theory to be dismissed since it contradicts it.
Or
D.The new discovery might further deny the theory since it presents evidence that contradicts it.
Itl be hard for them to decide you know, since this bigbang theory by darwin is widespread and cant be easily opposed..

Answer:
1.82°C
Explanation:
presumir inicial comprimento = l₀ = 5 m
dado que:
coeficiente de expansão (α) = 22 x 10⁻⁶, A variação no comprimento (ΔL) = 0.0002 m,
inicial comprimento = l₀ = 5 m
variação na temperatura = ΔT
para Calcular a variação na temperatura, nós usamos a fórmula:

substituindo valores:

variação na temperatura = 1.82°C
Answer:
Density is how compact something is. The relationship is M/V=D (Mass divided by Volume equals Density).
