ANOTHER RUNNING DOG
Explanation:
In the given question it is to find a suitable reference point to describe the motion of dog. Here I could suggest that it is better to compare the dog with another running dog to create the relative speed difference to get a reliable motion variation.
Because the motion of dog is in the linear with respect to the another dog and to the acceleration produced by the dog in the required interval is easy to calculate with respect to another dog which is already in motion.
Hence, I suggest that Motion of dog can be analysed better by analyse the motion variation of dog with another dog running.
The formula for the torque is
<span>τf = p F
where
</span><span>τf is the torque
p is the distance where the force is applied by the tendon
F is force applied by the tendon
If there are given values, substitute in the equation and solve for the torque.</span>
Answer: The sound intensity was reduced by -14.77 dB.
Explanation:
The level of the intensity of the sound with respect to the reference value is called Sound Intensity level.
I = Intensity of the sound
= Reference sound intensity
According to question, sound-reflecting windows that reduce the sound intensity level by 30.0 db .
Let the intensity of the sound be and reduced intensity be I.
The sound intensity was reduced by -14.77 dB.
