Consider two imaginary spherical surfaces of different radius, both centered on a point sound source emitting spherical waves.The power transmitted across the larger sphere is ________ the power transmitted across the smaller and the intensity at a point on the larger sphere is ________ the intensity at a point on the smaller.
A)greater than, the same as
B)greater than, greater than
C)greater than, less than
D)the same as, less than
E)the same as, the same as

The power transmitted across any spherical surface centered on the point source remains the same due to the conservation of energy. However, as the radius increases, the same power is spread over a larger area, leading to a decrease in intensity.
