5. Dos partículas parten al mismo instante desde el origen de un sistema de coordenadas. La una parte en dirección vertical con rapidez constante de 4 m/s. La otra parte desde el reposo y se mueve en dirección perpendicular a la anterior con una aceleración de 8 m/s2 durante los primeros 4s, para luego continuar moviéndose con velocidad constante. Desde el instante en que partieron, al cabo de cuánto tiempo las partículas estarán separadas 0.15 km.

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1

What sort of waves exhibit the doppler effect?

The friction of the water on a boat produces an acceleration of -10. m/s2. if the boat is traveling at 30. m/s and the motor is shut off, how long it take the boat to slow down to 5.0 m/s?
