Una partícula de 5*10^-7 kg y con -2*10^-2 C ingresa con una rapidez de 20000 m/s en una región donde existe un campo magnético uniforme cuyo módulo es de 1 T, tal como se muestra en el gráfico. ¿Después de qué tiempo saldrá de dicha región? (desprecie efectos gravitatorios?

If it takes a planet 2.8 x 10^8 s to orbit a star with a mass of 6.2 x 10^30 kg what is the average distance between the planet and the star

The a992 steel rod bc has a diameter of 50 mm and is used as a strut to support the beam. determine the maximum intensity w of the uniform distributed load that can be applied to the beam without risk of causing the strut to buckle. take f.s. = 2 against bucklin

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present
