Mary and her younger brother alex decide to ride the 26 ft diameter carousel at the state fair. mary sits on one of the horses in the outer section at a distance of 11.5 feet from the center. alex decides to play it safe and chooses to sit in the inner section at a distance of 6 feet from the center. what is mary's centripetal acceleration am compared to that of alex's centripetal acceleration aa?

A2 µc charge q1 and a 2 µc charge q2 are 0.3 m from the x-axis. a 4 µc charge q3 is 0.4 m from the y-axis. the distances d13 and d23 are 0.5 m. find the magnitude and direction of the resulting vector r. round your answer to the nearest tenth.

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.
