In a CAD package, mirror image of a 2D point P(5,10) is to be obtained about a line which passes

through the origin and makes an angle of 45° counterclockwise with the X-axis. The coordinates of

the transformed point will be

The pressure, temperature and velocity of air flowing in a pipe are 5 bar, 500 K and 50 m/s,

respectively. The specific heats of air at constant pressure and at constant volume are 1.005 kJ/kgK

and 0.718 kJ/kgK, respectively. Neglect potential energy. If the pressure and temperature of the

surroundings are 1 bar and 300 K, respectively, the available energy in kJ/kg of the air stream is

(A) 170 (B) 187 (C) 191 (D) 213

**The probability that a student knows the correct answer to a multiple choice question is

conditional probability that the student knows the correct answer is
(A) 2/3 (B) 3/4 (C) 5/6 (D)8/9**
