A special type of problem occurs with a Branchinstruction, since the processor cannot immediately determinewhether or not the branch will be taken. The next instruction willbe fetched before the determination is made. In this case, if thebranch is taken, then the following instruction would not beexecuted, and the most recently fetched instruction must bediscarded, and replaced by the branch target. Possible solutions tothis problem are ______ and _________.A) Stall pipeline until determination is made; Predicting theBranch decision before it is actually made.B) Stall pipeline until determination is made; Bypassing withadditional hardware.C) Bypassing with additional hardware; A Branch instruction musalways be followed by a NOP.D) Bypassing with additional hardware; Predicting the Branchdecision before it is actually made.

A manufacturing plant has a 25 KVA single phase motor with a lagging power factor of 0.85 and this motor gets its power from a nearby a.c. voltage supply. A power factor correction capacitor of 12 kVar is also connected parallel to the motor. (a) Calculate the real power (kW) consumed by the motor (3) (b) Calculate the input apparent power (S) taken from the supply (14) (c) The power factor is to be corrected or improved from 0.85 to 0.99 lagging. Calculate the rating (in Vars) of the capacitor required for this improvement. (8)

Why are friction brake used on electrical motors? Holding a motor position. Quicker stops. More precise stops. All of the answers above are correct. What can friction brakes be used for? Brake a motor in both directions. Control machine tools. secure cranes. All of the answers above are correct. How do fall-safe friction brakes normally react in case of a power failure? The brake is applied only for a limited time. The power failure does not affect the brake state. The brake is automatically disengaged. The brake is applied automatically. What is the effect of jogging on power contacts? It has no particular effect. It improves their conductivity. It reduces their life expectancy. It increases their life expectancy.

One-dimensional lattice. You have a one-dimensional lattice that contains NA particles of type A and NB particles of type B. They completely fill the lattice, so the number of sites is NA+NB . Write an expression for the multiplicity W(NA,NB) , the number of distinguishable arrangements of the particles on the lattice.
