Determine (1) The Sav • Scavenging ratio
(ii) The Scavenging efficiency 1111/ Trapping Efficiency.
A three-process cycle of an ideal gas, for which Cp = 1.064 and C₁ = 0.804 kJ/kgm.K, is initiated by an isentropic compression 1-2 from 103.4 kPa, 27°C to 608.1 kPa. A constant volume process 2-3 and a polytropic 3-1 with n = 1.2 complete the cycle. Circulation is a steady rate of 0.905 kgm/s, compute (a)QA, (b) WNET, (c) e, and (d) pm.
a. Design a sequential circuit with T flip-flops A and B and one input X. When X=0, the
state of the circuit remains the same. When X=1, the circuit goes through the state transitions
from 00 to 10 to 01 to 11, back to 00 and then repeats.

2. The displacement of a mass is given by the function
.
The tasks are to:
a) Draw a graph of the displacement y(m) against time t(s) for the time to .
b) Identify the position of any turning points and whether they are maxima, minima or points of inflexion.
c) Calculate the turning points of the function using differential calculus and show which are maxima, minima or points of inflexion by using the second derivative.
Compare your results from parts b and c.
Explain the Comparison of 3 mapping techniques between main memory to cache memory in the
tabular form. show how and from where CPU will access the word from the cache memory in each
mapping technique with the help of diagram. Take the word number as per your roll no. for example if
your roll no is 35 than you have to show how and from where CPU will access W35 from the cache
memory in case of each mapping technique with the help of diagram. Assume the main memory size as
16 KB, line size 128 bytes, cache size 1K bytes and k value is 4 .
) Assume data in A= 0110. Give the operand in B and logic micro-operation for manipulating the
bits in A as follows:
a) selective set of two most significant bits of A.
b) selective complement of two least significant bits of A.
c) mask the two most significant bits of A.
2. Generate MIPS code for the follow program using the updated code generation function. def sum(x, y) = x+y
A spring is such that a 2 lb weight stretches it by 6 in. There is a damping force present, with
the magnitude equal to 0.75|𝑣|. An impressed force of F(t) = 2 sin 8t is acting on the spring. If
the 2-lb weight is released from a point 3 in below the equilibrium point, describe the motion
A spring is such that a 4 lb weight stretches it by 0.64 ft. The weight is pushed up 1/3 ft above
the equilibrium point and started with an initial downward velocity of 5 ft/sec. The motion takes
place in a medium which furnishes a damping force of magnitude 0.25|𝑣| at all times. Describe
the motion.
