1.1- Como puedes ver, Juan y Carlos no se han puesto de acuerdo, pero han propuesto una serie de alternativas:
a- Mencionamos una de ellas y seguidamente que podían haber hecho:

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

Acar drives toward the right over the top of a hill, as shown below. which arrow represents the centripetal acceleration? w x y z

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
