... The days on Mars and Earth are of nearly identical length. Earth’s mass is 9.35 times Mars’s mass, Earth’s radius is 1.88 times Mars’s radius, and Mars is on average 1.52 times farther away from the Sun than Earth is. The Martian year is 1.88 times longer than Earth’s year. Assume that they are both ...

... An empty cup was tightly covered with plastic wrap, and a few grains of salt were sprinkled on top of the plastic. When a tuning fork was struck and placed slightly above the plastic wrap, the salt began to move. Which characteristic of waves does the movement of the salt best demonstrate? A. B. ...

... moment of inertia I decreases. Hence the angular speed (which is the magnitude of the angular velocity vz) must increase in order for the magnitude of Lz = Ivz to remain constant. 8-13 (d) The angular momentum L of a system is conserved only if no net torque acts on the system. This isn’t the case ...

... Example: Conservation of Angular Momentum A person sits on a piano stool holding a sizable mass in each hand. Initially, he holds his arms outstretched and spins about the axis of the stool with an angular speed of 3.74 rad/s. The moment of inertia in this case is 5.33 kg.m2. While still spinning, t ...
