Answer:
The water is 1310.75 meters deep.
Explanation:
The question gives us the speed of sound and the time the sonar signal takes to travel to the bottom of the water and back.
To find out the distance, we should first divide the time in half, so we only consider the time taken for the sound to reach the bottom of the water body.
This means:
Time = 1.75 / 2 = 0.875 seconds
The distance traveled in this time is:
Distance = Speed * Time
Distance = 1498 * 0.875
Distance = 1310.75 meters
Thus, the water is 1310.75 meters deep.
Answer:
fundamental frequency of pipe will be equal to 74 Hz
Explanation:
We have given for a particular organ pipe two adjacent frequency are 296 Hz and 370 Hz
Speed of the sound in air is 343 m/sec
We have to find the fundamental frequency for the pipe
Fundamental frequency will be equal to difference of the two adjacent frequency
So fundamental frequency = 370 - 296 = 74 Hz
So fundamental frequency of pipe will be equal to 74 Hz

Force of spring
The car moves down by 0.0001501 m
Answer: 1. A Unbalanced force and net force
Explanation:
The combination of all forces acting on a object is called a Net Force, and a Unbalanced force can cause an object to stop, start moving or change direction.
