If a and b are both int arrays, then a b; will

a. return true if a and b are aliases and return false otherwise

b. create an alias

c. return true if each corresponding element of b is equal to each corresponding element of a (that is, a[0] is equal to b(01, a[1] is equal to b[1] and so forth) and return false otherwise

d. copy all elements of b into a

e. copy the 0h element of b into the 0h element

Athin walled concentric tube exchanger is used to cool engine oil from 160°c to 60°c with water that is available at 25°c acting as a coolant. the oil and water flow rates are each at 2 kg/s, and the diameter of the inner tube is 0.5 m and the corresponding value of the overall heat transfer coefficient is 250 w/m2. oc. how long must the heat exchanger be to accomplish the desired cooling? cpwater=4.187 kj/kg-candcpengine el=2.035 kj/kg·°c, oil . 120]
