4. Rotating Experiments (Non-Inertial Reference Frame) Imagine that you are on a large rotating disk, with perpendicular to the disk at its center. Assume that you know that the center of the disk is fixed and that no real forces act on anything on the disk (except gravity (pulling downward) and the normal force (upward), which cancel each other out). As sume that changes only in magnitude, and that the rate of this change is constant. Is it possible for...

This is wrong.
PartI n an inertial frame of reference, a series of experiments is conducted. In each experiment, two or three forces are applied to an object. The magnitudes of these forces are given. No other forces are acting on the object. In which cases may the object possibly move at a constant velocity of 256 m/s? The forces applied are as follows: Check all that apply Hints Hint 1. Using the net force In an inertial frame of...

You are conducting an experiment inside an elevator that can move in a vertical shaft. A load is hung vertically from the ceiling on a string. The tension in the string is measured to be exactly equal to the force due to gravity on the load. No other forces are acting on the load. Which of the following statements about the elevator are correct? Check all that apply. The elevator is an inertial frame of reference. The elevator is not...

Consider an event with space-time coordinates (t=2.00s,x=2.50�108m)in an inertial frame of reference S. Let S' be a second inertial frame of reference moving, in the positive x direction, with speed 2.70�108m/s relative to frame S. Find the value of gamma that will be needed to transform coordinates between frames S and S'. Use c=3�108m/s for the speed of light in vacuum. Suppose that S and S' share the same origin; that is, at t = t' = 0, x =...
