Answer:
The intensity of sound wave at the surface of the sphere 
Explanation:
B = Bulk modulus
Intensity, 
The amplitude of oscillation of the sphere is given by:


Substitute v and A into Pmax




The intensity of the sound wave at a distance is given by:


The car heads east at an average speed of 50 miles per hour from the intersection point towards East. The truck heads east at an average speed of 60 miles per hour from the intersection point towards South.
The distance of car from the intersection point after t hours is
.
The distance of truck from the intersection point after t hours is
.
Since these distances are perpendicular to each other, distance apart d (in miles) at the end of t hours is

Thus the distance apart is 
There's the acceleration of the car that provides a force and the normal force of the seat cushion which pushes upwards against the passenger

These are known as balanced forces because they will not change the motion of the object, and it will remain at rest unless forces become unbalanced- meaning they would be unequal and not opposing.
