To solve this problem it is necessary to apply the concepts related to Sound Intensity. The unit most used in the logarithmic scale is the decibel and mathematically this is expressed as
Where,
= Sound intensity level in decibels
I = Acoustic intensity on the linear scale
Hearing threshold
According to the values, the total intensity is 32 times the linear intensity and the value in decibels is 83dB
So:
Therefore the sound intensity due to one person is 67.948dB
Coefficient of static friction = tan(a) = 0.4
r = 740 m
g = 9.8 m/s²
v = √(9.8 × 740 × 0.4) m/s
v ≈ 53.85908 m/s
Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation.
<span>When you apply force to move an
object at a distance, you are applying work. And work is energy in transit. The
answer is letter D. For example, you see a cart at a distance. You observe that
it is not moving. You want to transfer it to your backyard. You apply force to
the cart and observed that the cart is not at the same position as it was
before. You are applying work to the cart by transferring your energy to it.</span>
Answer: DENVER, COLORADO
Explanation: Temperature inversion is the term used to describe the increase in temperature as the height increases towards the Toposphere, Temperature inversion is a reverse of the normal temperature flow or distribution in the atmosphere.
Denver, Colorado has been known to be one of the Cities of the World where temperature inversion occurs frequently. The TOPOGRAPHY of Denver, Colorado makes it prone to temperature inversion, Denver, Colorado is located at the foot of mountains.
