A baseball is thrown into the air. It has an upward vertical velocity of 10m/s and an initial rightward horizontal velocity of 15m/s. Define upward vertical and rightward horizontal as positive directions. What is the resultant velocity (magnitude and direction relative to the rightward horizontal)?

J. j. thomson’s experiment disproved the theory that an atom

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.
