Al viajar a la luna, los astronautas a abordo de la nave espacial apolo se pusieron ellos mismos en una lenta rotacion para distribuir de manera uniforme la energia del sol. al comienzo de su viaje, aceleraron desde una rotacion hasta 1.0 revolucion cada minuto durante un intervalo de tiempo de 12 min. la nave espacial se puede considerar como un cilindro de diametro de 8.5m. determine a) la aceleracion angular y b) los componentes radial y tangencial de la aceleracion total lineal de un punto sobre la cubierta de la nave 5.0 min despues de que comenzo esta aceleracion

Which describe reflection? check all that apply. light bounces off a boundary.

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.
