Intensity of a sound wave. Assume that the source is located in the exact center of a large sphere, then the power of the sound wave is distributed evenly over the surface area of the sphere. Consider five scenarios where the power of the source depends on some constant and the radius of the sphere depends on some constant. Arrange the intensities of the sound waves from lowest to highest.

A60-kg box is being pushed a distance of 6.8 m across the floor by a force p with arrow whose magnitude is 162 n. the force p with arrow is parallel to the displacement of the box. the coefficient of kinetic friction is 0.24. determine the work done on the box by each of the four forces that act on the box. be sure to include the proper plus or minus sign for the work done by each force. (the floor is level and horizontal. forces that act on the box: pushing force p, frictional force f, normal force n, and weight mg.)
