(a)
Answer to Problem 17SGR
Thus, the height is 75,90,105,120.
Explanation of Solution
Given:
The distance d in kilometers that sound waves travel through water is given by
Where t is the time in seconds.
Calculation:
To find the table we use follow formula and simplify further as shown below:
TIME | HEIGHT |
1 | 1.6 |
2 | 3.2 |
3 | 4.8 |
4 | 6.4 |
Thus, the distance is
