Answer:
Image result for position (m) 80 60 40 20 - 20 -40 10 20 30 40 50 time (sec) What is the displacement from 15 to 40 sec? a 20 m b Оооо - 20 m -100 m с 100 m
The average velocity of the object is multiplied by the time traveled to find the displacement. The equation x = ½( v + u)t can be manipulated, as shown below, to find any one of the four values if the other three are known.
Explanation:
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.
0 to 30 takes more energy
