A series of parallel linear water wave fronts are traveling directly toward the shore at 15.5 cm/s on an otherwise placid lake.
A long concrete barrier that runs parallel to the shore at a distance of 3.10 m away has a hole in it. You count the wave crests and observe that 75.0 of them pass by each minute, and you also observe that no waves reach the shore at ±62.3cm from the point directly opposite the hole, but waves do reach the shore everywhere within this distance.
Part A
How wide is the hole in the barrier?
Part B
At what other angles do you find no waves hitting the shore?
Enter your answers numerically separated by commas.

Answer:
B = 2.5 10⁸ Pa
Explanation:
The volume modulus is defined by
B =
The negative fate is for the module to be positive since the volume change is negative
It is not necessary to reduce the volumes to the SI system, since they are both in the same units
B = =
B = 2.5 10⁸ Pa
