The result of
changing a physical sound wave into an analogous electrical signal using a
transducer (such as a microphone) is called analogue audio. In this system, the rapid electrical level is
directly proportional to the rapid air pressure taken by the transducer. The analogue
signal is then augmented and can be kept on an analogue medium such as tape or transformed
further into a succession of discrete mathematical numbers. The advantages of
using this device is that it yields a subtle sound and is pleasing to the ear
by pushing the signal level and overdriving it. But the disadvantages are
editing it would be tedious and prone to degradation.
Solution:
The coefficient of volume expansion
p = ΔV/V1Δt
3a = V2-V1/V1Δt
Given
a = = 11 x 10-6 / °C
V2 is the final volume
V1 is the initial volume = 100cm³
Δt = 100-0 = 100°C
Substitute
3(11 x 10-6) = V2-100/100(100)
33*10^-6 * 10000 = V2-100
33*10^-2 = V2-100
V2 = 100 + 0.33
V2 = 100.33
Hence the new volume is 100.33cm³
Answer:
A. the Moon has a larger acceleration than Earth, because it has a smaller mass.
Explanation:
A. the Moon has a larger acceleration than Earth, because it has a smaller mass.
According to Newton's second law F=ma, if we solve for a we have that
a=F/m, the smaller the mass the larger the acceleration given the force is the same, in this case the moon has a smaller mass and therefore a larger acceleration
