Suppose we have a JDBC Connection object c to a database, and this database has a relation
R(name, address, phone)
Columns name and address are of string type, while phone is an integer.
The following objects are also declared:
Statement s = null;
String q = "SELECT address, phone FROM R" + "WHERE name = 'Bill Gates'".
ResultSet r null;
There are many methods that could be applied to the given variables. When a method is applied to r, assume that it holds the result of query q. Then, identify a correct use of a method from the list below.
a) String x = r. getInt (1);
b) r = c. executeQuery (g) ;
c) int p = r. getInt (2);
d) r = s. executeQuery ( );

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
