A fan blade rotates with angular velocity given by wz(t) = y - Bt2, where y = 6.95 rad/s and ß = 0.73 rad/s. a) Calculate the instantaneous angular acceleration a, in rad/s? at t = 2.88 s. Insert your answer correct up to at least a third decimal place. b) Calculate the average angular acceleration aav-, in rad/s^2 for the time interval t = 0 to t = 3 s. Insert your answer correct up to at least a third decimal place.

2. Soledad Bautista, the engineering manager, delegates tasks as a good manager should. However, Mark Hermosa, the engineering director, has the bad habit of calling up Soledad unexpectedly to get detailed reports on various ongoing activities in Soledad's department. Soledad does not want to hold daily staff meetings in order to satisfy Mark's information needs because Soledad is quite certain that asking her professional staff to stand by and make daily reports will definitely be counterproductive, as all of them are known to prefer their independence. What should Soledad do?

Problem- Cargo ships can cause a lot of air pollution.Solution- to use nuclear powered ships since they hold a lot of energy and can travel for long distances. How it will work is that it will need a nuclear reactor at the bottom of the boat to heat up the water and then turn it to electricity to power the boat. The boat will be made out of graphene which is a tough material to avoid any leaks in the boat. It will also contain many control rods because nuclear power is so powerful that it can create to much energy to handle. With control rods, you can slow down this process and keep it in a controlled manner. Since cargo ships are already is the ocean, there will be no need for any extra materials to make it work. -Do you think this will work? Why/Why not? -What do you think is wrong with it/ How can this be improved? Please send this to someone else I need to record 50 responses for a science project. Thank you!

Task 1: As a maintenance manager at a plant, you are required to update the existing maintenance plan for one of the critical plant's systems. This entails defining economical and technically practical maintenance interventions while considering a high level of safety. What are the potential approaches for maintenance interventions that could be included in the current maintenance plan? Provide definitions for each of them, outline their advantages and disadvantages, and support them with real-life examples. - State two potential maintenance decision-making strategies you could adopt and clarify their steps and logic of implementation. Introduce and explain the concept of Prognostics and Health Management (PHM). Describe what PHM entails, as well as its benefits and expectations. - Explain how the frequency of planned maintenance interventions can impact production and costs for a specific component. Clarify the process for selecting the best maintenance intervention approach for that…
