Write the SQL statement to create a five-field table to contain sample student information. The constraints that need to be satisfied by the attributes of this table are as follows:.a) the attribute First_Name is mandatory and can have up to 16 characters, b) the attribute Last_Name is mandatory and can have up to 16 characters, c) the attribute Date_Of_Birth is of type date is required, d) the StarID field identifies each student and is 8 characters longe) the GPA field is numeric that can be 2 digits with 1 decimal place. f) Be sure to select column names, types, and constraints that are appropriate based on the description above.

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
