A source of sound is located at the center of two concentric spheres, parts of which are shown in the drawing. The source emits sound uniformly in all directions. On the spheres are drawn three small patches that may or may not have equal areas. However, the same sound power passes through each patch. The source produces 2.1 W of sound power, and the radii of the concentric spheres are rA = 0.59 m and rB = 0.85 m. (a) Determine the sound intensity at each of the three patches. (b) The sound power that passes through each of the patches is 2.00 10-3 W. Find the area of each patch.
The scale of a spring balance reading from 0 to 235rm {N} has a length of 15 rm{cm}. A fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.7rm {Hz}. What is the mass of fish? In Kg.
The flywheel of an engine has a moment of inertia 2.40- {rm kg} cdot {rm m}^{2} about its rotation axis. What is its final kinetic energy.
A cyclist is traveling at an initial speed of 10.0m/s. She accelerated at a rate of 0.500m/s^2. What is her final speed after 9.
A ship sets out to sail to a point 141km due north. An unexpected storm blows the ship to a point 138 km due east of its starting point. (a) How far (in km) and (b) in what direction (as an angle from due east, where north of east is a positive an..
A point P is on a rim of a wheel of radius 2.0m. At time t=0 wheel is at rest and P is on the x-axis. The wheel undergoes a uniform angular acceleration of 0.01 rad/s2 about the center O. Find out the time t, when P returns to an original position on..
Saturn's moon Titan is the largest moon in the solar system. Its mostly-nitrogen atmosphere exerts a pressure of 1.60×105 Pa at the moon's surface.
A Sphere on a Horizontal Surface starts from Rest. If the Force is applied facing to the Right at the Top furthest Point of the Sphere from the Horizontal Surface, the Sphere will start experiencing Roll and Slip at the same time. In which directi..
