A uniform cylinder of mass m=8.26 kg and radius R=0.147 m is released from rest on an inclined plane (theta=42.4 deg) and rolls without slipping onto a horizontal surface. The center of mass falls h=0.804 m in the process. What is the magnitude of the angular velocity just before the cylinder reaches the horizontal surface?
A wire is moving perpendicularly through a magnetic field of strength 0.100 T with speed 60.0 m/s. If the potential difference between the ends of the wire is 2.00 V, what is the length of the wire?
βAn observer that is standing 12m from a stereo sound speaker perceives the sound level from the speaker to be 60 dβ. What is the decrease in the physical intensity in watts/m2
Sound is considered an electromagnetic wave. The electric field in an electromagnetic wave is parallel to the magnetic field. An accelerating reference frame is considered as an inertial reference frame. In the photoelectric effect, light acts like a..
A potter's wheel (a solid, uniform disk) of mass 5.7 kg and radius 0.65 m spins about its central axis. A 2.1 kg lump of clay is dropped onto the wheel at a distance 0.41 m from the axis. Calculate the rotational inertia of the system.
