Ahorizontal turntable is made from a uniform solid disk and is initially rotating with angular velocity of 6.9 rad/s about a fixed vertical axis through its center. the turntable has a radius of 0.11 m and a moment of inertia of 0.006655 kg m2 about the rotation axis. a piece of clay, initially at rest, is dropped onto the turntable and sticks to it at a distance d= 0.04 m from its center as shown in the figure. the final angular velocity of the turntable and the clay after the collision is 4 rad/s. treat the piece of clay as a point particle and assume that there are no external torques acting on the system around the rotation axis. which of these quantities are conserved during the collision? a. the total linear momentum of the clay and the turntable. b. the total angular momentum of the clay and the turntable about the rotation axis. c. the angular momentum of the turntable about the rotation axis. d. the angular momentum of the clay about the rotation axis. e. the mechanical energy of the clay and the turntable

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.
