A solid wood door 1.00 mm wide and 2.00 mm high is hinged along one side and has a total mass of 43.0 kgkg . Initially open and at rest, the door is struck at its center by a handful of sticky mud with mass 0.600 kgkg , traveling perpendicular to the door at 14.0 m/sm/s just before impact.

A) Find the angular speed of the door. B) Does the mud make a significant contribution to the moment of inertia?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc

This is a form of winter precipitation. it is frozen precipitation falling as ice pellets. snowflakes melt into raindrops as they pass through a thin layer of warmer air. the raindrops then refreeze into particles of ice when they fall into a layer of sub-freezing air near the surface of the earth. this precipitation is called a) hail. b) rain. c) sleet. d) snow.

Which of the following statements correctly describes a transformer?
