Answer:
Frequency
Explanation:
As we know that the characteristics of sound is as following
Loudness : loudness of sound depends on the amplitude of sound so increasing the loudness will cause the amplitude to increase.
Quality of sound : Quality of sound depends on the type of waveform. For different waveform the quality of sound is also different.
Pitch of sound : Pitch depends on the frequency of the sound which means if the frequency of sound is more then its frequency will be more
the correct answer will be
Frequency
The correct option is (B) h(t) = -16t2 + 50t + 3
An equation like this has the generic form h(t) = at2 + v0t + h0,
where; a is the gravitational constant,
v0 is the initial velocity, and
h0 is the initial height.
Given that the gravitational constant is -16.
The equation h(t) = -16t2 + 50t + 3 is given by the starting velocity of 50 and the initial height of 3.

Answer:
97.03%
Explanation:
The equation for volumetric expansion due to thermal expansion is as follows
V/Vo=(1+γΔT)
V=final volume
Vo=initial volume
γ=coefficient of volume expansion=3.2 × 10–5 K–1
ΔT=
temperature difference
assuming that the earth is a sphere the volume is given by
V=(4/3)pi R^3
if we find the relationship between the initial and final volume we have the following
taking into account the previous equation
r/ro=(1+γΔT)^(1/3)
r/r0=(1-3.2x10-5(3000-300))^(1/3)=
r/ro=0.9703=97.03%
