Question 2. (13 points) The figure below shows a metallic bar of length 0.240 m, mass 0.100 kg and of negligible electrical resistance moving from left to right under the action of an applied force $F_{app}$. The conducting bar slides along two fixed parallel conducting rails, and a magnetic field points everywhere into the page. A terminating resistor completes a circuit loop through which current can flow. Circle one of the underlined choices. As the rod moves rightward, the area of this loop (increases or decreases), leading to an (increasing or decreasing) magnetic flux. This causes an induced current to flow (CW or CCW), hence the current is (upward or downward) within the rod leading to a magnetic force $F_a$ toward (left or right). If the velocity is faster, the induced current will (increase, decreases or remain.) If the rod moves at a constant velocity of 1.5m/s, and the B field is 5 T, the resistance is 20 ohm, please find (1) the induced emf, (2) the induced current, (3) the power consumed by the resistor, (4) the amount of applied force needed to maintain the constant velocity.

1. Consider a turbulent flow through the tube shown below, with velocity profile $u_T = u_0(1 - (r/R)^{1/7})$, and a laminar flow through the same tube, with velocity profile $u_L = A(1 - (r/R)^{1/2})$. Flow ?R x (a) Find the constant A in terms of $u_0$ such that the two flows have the same total flow rate. (b) Sketch the two velocity profiles and use the definition of turbulent flow to explain why they look different.

4.96 m rijit çubuk (1) ? 77777 12.4 m 55 kN The rigid horizontal bar articulated at the left end was supported by 2 elastic bars with an elastic modulus of 207 GPa. Rod number 1 has a length of 3.7 m and a cross-sectional area of 8.3 cm²; Since the rod number 2 has a length of 2.2 m and a cross-sectional area of 1.6 cm², as a result of the 55 kN force acting from the right end: What will be the internal force on bar 1? What is the internal force in bar 2? How many mm does point C of the rigid bar collapse?

2. (9 marks) For each of the statements below, circle the "T" letter following the statement if the statement is true; circle the "F" letter following the statement if the statement is false. (a) When a Memory-Management Unit (MMU) is used, the user program deals with logical addresses; it never sees the real physical addresses. T F (b) Separating code and data and generating reentrant code in general increases the performance of a paging system. T F (c) One must generate relocatable code for a routine if the final binding of instructions and data to memory for that routine is delayed until load time. T F (d) When the high level synchronization construct monitors are used, if no process is suspended on the condition variable x then the x.signal operation has no effect. T F (e) The size of page table must be the same for all processes in any given system. T F (f) When a hashed page table is used, the correct frame number for each logical address can always be found with one single memory access. T F (g) Associative registers can be used to improve the performance of memory management systems that use the Inverted Page Table Architecture. T F (h) After a page fault, resumption of the program starts by executing the instruction that immediately follows the instruction that caused the page fault. T F (i) When Virtual Memory is used, decreasing the page size generally decreases the number of page faults. T F

[Probability] A dart board is positioned on the disk $x^2 + y^2 < 4$. A robot is randomly throwing darts at the board with a probability density function of $D(x, y) = K(4 - x^2 - y^2)$. (a) Find the value of $K$ which normalizes the function (i.e. makes a valid probability density function). (b) Find the probability the robot will throw the dart so that it lands within 1 unit of the bullseye (at the origin).
