Una pelota rueda por una pendiente con aceleración constante. Cuando pasa por un punto P su velocidad es 1,2 ms-1 y al cabo de un breve periodo de tiempo pasa por el punto Q con una velocidad de 2,6 ms-1 .
a. Determine ¿cuál es la velocidad media entre P y Q?
b. Si tarda 1,4s en ir de P a Q, calcule ¿cuál es la distancia PQ?
c. Determine ¿cuál es la aceleración de la pelota entre P y Q?
d. Explicar si la aceleración media en el tramo P y Q es la misma que la calculada en la pregunta c

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
