Because we should convert units within the metric system
V = 0, a increasing
a = 0
v increasing, a increasing
v decreasing, a decreasing
Answer:
A
Explanation:
because you cannot seperate the matter duhhh hahha
Something that is definitely true is that the constant acceleration has to affect the monkey and the banana beacuse both are affected by the gravity. Gravity imparts exactly the same acceleration on both things while falling and it affects them in the same way
Answer: The sound level of the singers is
86.96dB
Explanation:
sound wave can be described by the intensity of sound, which is measured in decibels. The actual intensity, in watts per square meter, varies over a very wide range, so the logarithmic scale is more convenient in intensity characterization. The intensity in decibels is given by 10log10 (I/Io)
Where Io= 10^-12W/m^2 is called the threshold of hearing.
If the intensity of sound produced by 1 singer is I the intensity of sound of 36 singers will be 36I
X = 10log10 (36I/ Io)
Transforming, we have,
X = 10log10 36 + 10log10(I/Io)
X = 10log10 36 + 71.4 fb
X = 15.56 + 71.4 fb
X = 86.96dB
