Which is a component of a wind energy conversion system? O a. inverter O b. charge controller O c. yaw drive O d. battery bank

In a solar dish, which device converts the thermal energy of fluid into mechanical energy? O a. gas turbine O b. steam turbine O c. generator O d. heat engine

2. How does the magnetic blood flow meter work? Explain briefly.

I have a wooden toy train that runs on wooden tracks. I would like to place two ESP-WROOM-32 Boards on top of the train. Broadcast communication (which involves radio frequency, not Wi-Fi) would help communicate about the train's lateness to five other wooden trains on the same track. Local communication would help communicate to the train station about the train's lateness. I would also need radio frequency Tx-Rx Modules for discharging and undergoing the signal, and repeaters just in case the signal loses power due to long-distance traveling. My wooden train should be automated. It should run at 4 inches per second, keep a minimum distance of 30 seconds away from the other wooden trains, and make a 17-second-long stop every 500 seconds. What's the procedure to connect the components? What's the Arduino code (C++) for this project?

1. i. Mention any three factors that determine the output of wind energy conversion system. A) Length of the blade, rotor swept area, the wind speed B) Length of the blade, rotor swept area, the wind temperature C) Length of the blade, rotor swept area, Rain fall D) None
