The electric field in an electromagnetic (EM) wave is \( \vec{E}=\sqrt{6 \pi} \hat{i} \sin \left[2 \pi\left(10^{6} z-3 \times 10^{14} t\right)\right] \). What is the intensity of the EM wave and the number of photons per second falling on the unit area of a perfectly reflecting screen kept perpendicular to the direction of propagation? When a photon in this beam is reflectic from the screen, what is the impulse it imparts to the screen? Use this to find the pressure exerted bythe EM wave on the screen.

Challenges of Parallel Processing - The application of multiprocessors ranges from running independent tasks with essentially no communication to running parallel programs where threads must communicate to complete the task. To overcome these hurdles typically requires a comprehensive approach that addresses the choice of algorithm and its implementation, the underlying programming language and system, the operating system and its support functions, and the architecture and hardware implementation. However, in age of Artificial Intelligence (AI), research on how AI can eliminate these challenges or reduces it. Instructions: Proper research is needed with an abstract, introduction, research questions, body of the paper, and findings.

A solid cylinder with one end fixed is subjected to torque T. The radius of the cylinder is R. The material is homogeneous with Young's modulus E and shear modulus G. When yielding occurs, the material follows elastic perfectly plastic constitutive relation as shown below. 1) If the deformation is linear elastic, how to calculate the stress level at an arbitrary point? (Write down the stress equation using the given parameters) 2) Calculate the magnitude of T and $\Phi$ (angle of rotation) when initial yielding occurs. 3) Calculate the magnitude of T and $\Phi$ (angle of rotation) when $\frac{1}{3}$ of the material reaches the yielding point. 4) Calculate the magnitude of T and $\Phi$ (angle of rotation) when half of the material reaches the yielding point. 5) Calculate the magnitude of T and $\Phi$ (angle of rotation) when the entire material is yielded. 6) Plot the T vs $\Phi$ curve over the entire deformation process and explain the trend. (Hint: you can normalize the axis if needed) 7) Please use both Von Mises criterion and Tresca criterion to calculate the equivalent yield stresses when initial yielding occurs. Explain which criterion is more conservative. Why?

Question 5 0.2m 0.3 kg P 0.5kg Fig. 1 A light inextensible string of length 1 m passes through a small smooth hole A in a fixed smooth horizontal plane. One end of the string is attached to a particle P, of mass 0.5kg, which hangs in equilibrium below the plane. The other end of the string is attached to a particle Q, of mass 0.3 kg, which rotates with constant angular speed in a circle of radius 0.2 m on the surface of the plane (see Fig. 1). (i) Calculate the tension in the string and hence find the angular speed of Q. (ii) Find the speed of Q. [4] (iii) Find the time taken for particle Q to complete one full circle around the hole
