Answer:
The sound intensity is still the same. The sound intensity level does not depend on the number of sound sources but only the wave properties of the wave medium and the properties of the sound source. The wave properties of the medium includes the density and also the temperature.

Answer:
<u>The car's average speed is 32 kilometers per hour</u>
Explanation:
1. Let's review the information given to us to answer the question correctly:
First two hours = 60 kilometers
Next two hours = 68 kilometers
2. What is the car's average speed?
Total distance traveled by the car = 60 + 68
Total distance traveled by the car = 128
Total time of travel = 2 + 2 hours
Total time of travel = 4 hours
Average speed = Total distance/Total time
Replacing with the real values, we have:
Average speed = 128/4
<u>Average speed = 32 kilometers per hour</u>
Answer:
Time will be 5 sec
And maximum height will be 1200 feet
Explanation:
We have given that initial velocity of the object u = 160 ft/sec'
Function of height 
Take derivative of the distance
We know that first derivative of distance is velocity
So 
At maximum height we know that velocity is zero
So 
t = 5 sec
So it will take 5 sec to reach maximum height
Now maximum height will occur at t = 5 sec
So maximum height =
