Un día de tormenta vemos un rayo y cronometramos el tiempo que tarda en escucharse el trueno. El resultado es de 12 s. ¿A qué distancia está la tormenta? Vel. de la luz = 300.000 Km/s, Vel. del sonido= 340 m/s 1. 4800m
2. 4080m
3. 480m
4. 2700m

The 20@kg wheel has a radius of gyration about its center g of kg = 300 mm. when it is subjected to a couple moment of m = 50 n # m, it rolls without slipping. determine the angular velocity of the wheel after its mass center g has traveled through a distance of sg = 20 m, starting from rest.

The slope of a velocity time graph over any interval of time gives the during that interval

Two point charges are on the y axis. a 3.90-µc charge is located at y = 1.25 cm, and a -2.4-µc charge is located at y = −1.80 cm. (a) find the total electric potential at the origin. v (b) find the total electric potential at the point whose coordinates are (1.50 cm, 0). v
