Consider a paged-segmentation memory-management scheme that allows up to 8 segments per process, laid out over pages of size 16KB. Let the segment sizes of three processes P1, P2 and P3 be as follows:
Process Segment Number Segment Size
P1 0 81KB
P1 1 116KB
P1 2 32KB
P2 0 48KB
P2 1 60KB
P2 2 200KB
P2 3 142KB
P3 0 146KB
P3 1 72KB
Compute the internal fragmentation for each segment, and determine the total internal fragmentation for each process. Based on this computation, identify the TRUE statement among the following?
A. Only one out of the three segments of P1 has internal fragmentation. B. All the segments of P2 have internal fragmentation. C. All the segments of P1 have internal fragmentation. D. All the segments of P3 have internal fragmentation

Tom is having a problem with his washing machine. he notices that the machine vibrates violently at a frequency of 1500 rpm due to an unknown rotating unbalance. the machine is mounted on 4 springs each having a stiffness of 10 kn/m. tom wishes to add an undamped vibration absorber attached by a spring under the machine the machine working frequency ranges between 800 rpm to 2000 rpm and its total mass while loaded is assumed to be 80 kg a) what should be the mass of the absorber added to the machine so that the natural frequency falls outside the working range? b) after a first trial of an absorber using a mass of 35 kg, the amplitude of the oscillation was found to be 10 cm. what is the value of the rotating unbalance? c) using me-3.5 kg.m, find the optimal absorber (by minimizing its mass). what would be the amplitude of the oscillation of the absorber?
