A ball of mass and radius R rolls without slipping from rest down a ramp and onto a circular path of radius 0.480 m. The initial height of the ball is h = 0.360 m. At the bottom of the circular path, the magnitude of the normal force on the ball is 2.00g. The ball consists of an outer spherical shell (of a certain uniform density) that is glued to a central sphere (of a different uniform density). The rotational inertia of the ball can be expressed in the general form = βR2, but β is

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

What is a carrier wave and how does it affect what you hear on the radio

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
