Dos poleas de diferente tamaño se encuentran unidas por medio de una correa que no desliza. Los radios de las poleas son 30 cm y 10 cm. La polea mayor se encuentra unida a través de su centro con un motor que se encuentra girando con una velocidad angular de 8 rad/s. Determine: 1)La velocidad tangencial de la polea 1. 2)La velocidad angular que tendrá la polea 2. 3)El radio que tendría que tener otra polea (3) unida a la polea menor por medio de otra correa para que esta gire con una velocidad angular de 2 rad/s.

Awave with a frequency of 500 hz is traveling at a speed of 100 m/s.what is the wavelength?

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a

(8%) problem 12. a bowling ball of mass mb 3 kg 's rolled down the lane with a velocity ofy-2/ m s lt strikes a single remaining pin mp 0.93 kg head on. after the collision the bowling ball has a velocity (in the same direction) of v2 1.1 m/s. = ▲ 33% part (a) write an expression for the velocity of pin in the horizontal direction after the impact, im ,, 33% part (b) what is the pins speed in ms? 33% part (c) assuming the coefficient of friction s μ,-0.1. how far in meters could the pin slide before stopping if it doesn't topple?
