Modify the included program to implement the strict alternation solution to achieve mutual exclusion. It does not matter whether Thread 0 goes first or Thread 1, but it is important that the thread strictly alternate.PROGRAM:#include #include #include int count;int turn = 0; // Shared variable used to implement strict alternationvoid* myFunction(void* arg){int actual_arg = *((int*) arg);for(unsigned int i = 0; i < 10; ++i) {// TODO:// Make sure that the thread waits for its turn// before it enters the critical region.//// HINT: The thread ID is stored in actual_argwhile(turn != actual_arg);// Beginning of the critical regioncount++;std::cout

A rocket fires two engines simultaneously. One produces a thrust of 785N directly forward while the other gives a thrust of 519N at an angle 18.8 degrees above the forward direction. Find the deviation of the direction (relative to the forward direction) of the resultant force which these engines exert on the rocket.

Lindsey wants to determine how the sales of each month contributed to the total sales. Calculate this information for her as follows: a. In cell B13, insert a formula without using a function that divides the total sales for January (cell B10) by the total sales to date (cell I10). b. Use an absolute reference to cell 110 in the formula. c. Use the Fill Handle to fill the range C13:G13 with the formula in cell B13.

You are trying to select the BEST network topology for a new network based on the following requirements. The design must include redundancy using a minimum of two cables to create the network. The network should not be prone to congestion. Therefore each device must wait for its turn to communicate on the network by passing around a token. Which of the following topologies would BEST meet the client's requirements?A - StarB - BusC - MeshD - Ring

Three piezometers located 1000 m apart bottom in the same horizontal aquifer. Piezometer A is due south of piezometer B, and piezometer C is to the east of the line AB. The surface elevations of A, B, and C are 95 m, 110 m, and 135 m respectively. The depth of water in A is 5 m, in B is 30 m, and in C is 35 m. Determine the direction of groundwater flow through the triangle ABC and calculate the hydraulic gradient.

To understand the concept of moment of a force and how to calculate it using a scalar formulation.The magnitude of the moment of a force with a magnitude F around a point O is defined as follows:MO=Fdwhere d is the force's moment arm. The moment arm is the perpendicular distance from the axis at point O to the force's line of action.A stool at a restaurant is anchored to the floor. When a customer is in the process of sitting down, a horizontal force with magnitude F1 is exerted at the top of the stool support. When the customer is seated, a vertical force with magnitude F2 is exerted on the stool support. If the maximum moment magnitude that the stool support can sustain about point A is MA = 160 Nm , what is the maximum height d1 that the stool can have if the magnitudes of the two forces are F1 = 300 N and F2 = 720 N . Assume that moments acting counterclockwise about point A are positive whereas moments acting clockwise about A are negative.

Waste cooking oil is to be stored for processing by pouring it into tank A, which is connected by a manometer to tank B. The manometer is completely filled with water. Measurements indicate that the material of tank B will fail and the tank will burst if the air pressure in tank B exceeds 18 kPa. To what height h can waste oil be poured into tank A? If air is accidentally trapped in the manometer line, what will be the error in the calculation of the height?
