Calculate the kinetic energy of the following object.
the earthr with a mass of 5.97 x 10(24) moving at a velocity of 461 m/s

The frequency of the fundamental of the guitar string is 320 hz. at what speed v do waves move along that string?

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c

Why does gravity have a lesser than grater effect on higher altitudes?
