What are block and stream ciphers? What are the differences, and when would you use one vs. the other?2 AnswerWhat are the differences between inline and block level elements? 1 AnswerA block of mass 10 kg rests on a horizontal floor. The acceleration due to gravity is 9.81 m/s2 . The coefficient of static friction between the floor and the block is 0.2. A horizontal force of 10 N is applied on the block The magnitude of force of friction (in N) on the block is____0 AnswerStream A with specific heat capacity CPA = 2000 J/(kg K) is cooled from 90 °C to 45 °Cin a concentric double pipe counter current heat exchanger having a heat transfer area of 8 m2 . The cold stream B of specific heat capacity CPB = 1000 J/(kg K) enters the exchanger at a flow rate 1 kg/s and 40 °C. The overall heat transfer coefficient U 250 W/(m2 K). Assume that the mean driving force is based on the arithmetic mean temperature difference, that is, , , , , 2 2 A in A out B in B out AMTD T T T T T where Ti in, and Ti out , refer to the temperature of the i th stream (i = A, B) at the inlet and exit, respectively. The mass flow rate of stream A (in kg/s), is _______________ (rounded off to two decimal places).0 AnswerA continuous cell culture being carried out in a stirred tank reactor is described in terms of its cell mass concentration X and substrate concentration S. The concentration of the substrate in the sterile feed stream is SF = 10 g/L and yield coefficient Yx/s = 0.5. The flow rates of the feed stream and the exit stream are equal (F=5 mL/min) and constant. If the specific growth rate (h-1) 𝜇 = 0.3 𝑆 (1+𝑆) , the steady state concentration of S is _____ g/L0 AnswerExplain block replacement strategies to replace a block, with example when a cache?1 AnswerConsider the reference stream 123421562123763, how many page faults while using FCFS and IRU?1 AnswerA plane-strain compression (forging) of a block is shown in the figure. The strain in the z-direction is zero. The yield strength (Sy) in uniaxial tension/compression of the material of the block is 300 MPa and it follows the Tresca (maximum shear stress) criterion. Assume that the entire block has started yielding. At a point where 40 MPa (compressive) and 0, x xy the stress component y is0 AnswerWhat are the differences between relative and absolute in CSS?1 AnswerThe packing of an existing absorption tower is replaced with a new type of packing. The height of the packing and the inlet conditions are maintained the same as before. T ests reveal that the number of transfer units is lowe1 AnswerA certain processor deploys a single-level cache. The cache block size is 8 words and the word size is 4 bytes. The memory system uses a 60-MHz clock. To service a cache miss, the memory controller first takes 1 cycle to accept the starting address of the block, it then takes 3 cycles to fetch all the eight words of the block, and finally transmits the words of the requested block at the rate of 1 word per cycle. The maximum bandwidth for the memory system when the program running on the processor issues a series of read operations is __________× 10^6 bytes/sec.0 AnswerA metal block having sides 10 cm, 15 cm, 30 cm has cut into equal cubes. If the block is exhausted completely what will be the least possible number of cubes? 0 AnswerA layer-4 firewall (a device that can look at all protocol headers up to the transport layer) CANNOT -gate-cse-20111 AnswerA bullet of mass 10 g travelling horizontally with a velocity of 150 ms-1 strikes a stationary wooden block and comes to rest in 0.03 s. Calculate the distance of penetration of the bullet into the block. Also calculate the magnitude of the force exerted by the wooden block on the bullet. - Physics Cbse class 11 1 Answer What do you mean by social differences? How do social differences create social division in society? -civics-class 10-cbse1 AnswerWhat will happen if you put return statement or System.exit () on try or catch block? Will finally block execute.1 AnswerWhat is the differences between $a != $b and $a !== $b?1 AnswerWhat is Try Block?1 AnswerWhat are the differences between ES6 class and ES5 function constructors?1 AnswerA solid block of 2.0 kg mass slides steadily at a velocity V along a vertical wall as shown in the figure below. A thin oil film of thickness h = 0.15 mm provides lubrication between the block and the wall. (Gate 2018 Mechanical engineering)0 Answer
