- Un corredor realiza tres desplazamientos, el primero de 3 km al sur, el segundo de 1 km al este, y el último de 2 km al norte.
Calcula: a) ¿Cuál es la distancia total recorrida por el depor-
tista? b) Encuentra gráficamente cuál es la magnitud del des-
plazamiento resultante, así como la dirección en que actúa y el
valor del ángulo medido respecto al este.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

i think the answer is a, hope this : )
