Suppose junk emails delivered to one's inbox follow a poisson distribution, with a constante average rate of 3 emails per hour. What is the probability that one junk email is received within half an hour after creating an email account?
ESCOJA LA MEJOR CONTESTACIÓN: 6. Cuando no hay movimiento los valores de la distancia es constante pero la rapidez y la aceleración serán: o iguales en magnitud o cero o diferentes de cero o ninguna de las anteriores
10 poin La expresión correcta de la constante de equilibrio que aplica a la hidrólisis para la sal NaCH3COO es: RAK = [Na+] (CH3C001 B. K = ([H30+][CH3COO-IY[CH3COOH) OCK = [CH3COOHY(H30* (CH3C001) OPK = ([OH-] [CH3COO-IMCH3COOH] OEK = ((OH) [CH3COOHIM CH3COO")
Constante Periodic Table A particle with a charge ol - 5.40 1C is moving in a uniform magnetic field of B = - 1.25 T The magnetic force on the particle is measured to be --(3.00x10-'N ) + ( 7.60x10-N). Part A Are there components of the velocity that cannot be determined by measuring the forca? View Available Hint(s) yes no O Submit Part B Calculate the component of the velocity of the particle. Express your answer in meters per...
2. Un tren se mueve a una rapidez constante de 60.0km/h durante 40.0min en dirección este, luego a 50.00 al este del norte por 20.0min y finalmente al oeste por 50.0min. Cual es la velocidad promedio del tren en todo este movimiento?
Constante Part A The mechanism shown in the figure (Figure 1) used to raise a crate of supplies from a ship's hold. The crate has total mass 38 kg Arope is wrapped around a wooden cylinder that turns on a metalade. The cylinder has radius 0 33 m and a moment of inertia-2.1 kg m? about the le. The crate is spended from the free end of the rope. One end of the sole plots on frictions bearings, a crank...
