Consider the following two threads of a process, to be run concurrently in a shared memory (all variables are shared between the two threads): Assume the following: 1. a single-core system 2. load and store are atomic (i.e. they start and finish without interruption) 3. x is initialized to 0 before either thread starts, and 4. x must be loaded into a register before being incremented (and stored back to memory afterwards). The following questions consider the final value of...

27. A sign of mass 100.0 kg is hanging by a cable from the end of a support rod 0.400 m long. The support rod is perpendicular to the wall. Another cable, making an angle of 60 with the wall, is attached to the end of the support rod. The support rod has a mass of 36.0 kg, and has uniform density so its center of mass is in the middle of the rod. a. Calculate the tension in the...

(a) A physics lab instructor is working on a new demonstration. She attaches two identical iron globes with mass m = 0.210 g to threads of length L as shown in the Both globes have the same charge of 7.60 nc, and are in static equilibrium when θ = 4.95°. What is L (In m)? Assume the threads are massless. (b) what if? The charge on both globes is increased until each thread makes an angle of θ = 9.90° with the...

21.61 -- CP Two small spheres with mass m = 15.0 g are hung by silk threads of length L = 1.20 m from a common point (Fig. P2160). When the spheres are given equal quantities of negative charge, so that 41 = 42 = 4, each thread hangs at 8 = 25.0% from the verti- cal. (a) Draw a diagram showing the forces on each sphere. Treat the spheres as point charges. (b) Find the magnitude of q. (c)...

Two steel pipes (with Young's modulus E=200*10^9 N/m^2) are anchored within a concrete wall so they stick out horizontally, parallel to the ground below. They each have a length of l=2.0 m, but the lower one is solid with a radius r=2.0 cm and the upper one is hollow with an inner radius b=2.0 cm. A person with a mass of 70 kg then alternately stands on the free end of either pipe, causing each pipe to bend the same...
