You are designing a new eco-friendly thermal coffee mug. It is shaped like a small globe to minimize surface area, which is only about 0.04m^2. You use two 0.003m layers of recyclable PETE which has a thermal conductivity, k, of 0.2W/mK around a 0.01m layer of dead air, with a thermal conductivity of 0.026W/mK. Since this is for hot coffee, use a temperature difference of 40K. Q = Ax (T2-T1) / (R1 + R2 + etc) R =x/k. What is the R-value for each of the two PETE layers

The student engineer of a campus radio station wishes to verify the effectiveness of the lightning rod on the antenna mast (see the figure below). The unknown resistance Ry is between points C and E. Point E is a "true ground," but is inaccessible for direct measurement because the stratum in which it is located is several meters below Earth's surface. Two identical rods are driven into the ground at A and B, introducing an unknown resistance Ry. The procedure for finding the unknown resistance Ry is as follows. Measure resistance R, between points A and B. Then connect A and B with a heavy conducting wire and measure resistance R2 between points A and C.

task 2 A. The average surface temperature on Mars is -63 °C, so temperature control is used to drive a heatingelement, or a heater, inside the Martian home. You decided to use an electric heater placed in the middle of the home as your heat source. To measure the temperature, you decided to put athermocouple above the door entrance:1. In order to guarantee that the Martian people will live, you decided to make a closed-loopcontrol system. Based on the exact scenario given, clarify the following:a. Which part resembles the feedback path.b. What is the set value.c. What are the controlling and the controlled variables.d. When you build the Martian dome for the first time, the temperature is -63 C, calculate the absolute error.e. If your thermo-couple measures the values from is -200 to 1500,calculate the error as a percentage. 2. Consider the case when an astronaut comes from the Martian surface into the home.Temperature is expected to drop due to the exposure to the Martian cold wind.…
