calculate the energy transfer rate in w/m² across 6 in wall of firebrick with a temperature difference across the wall of 55°C. the thermal conductivity of the firebrick is 0.65 BTU/hr ft °F.
Calculate the wavelength of radiation emitted producing a line in Lyman Series, when an electron falls from the third orbit in hydrogen atom. [RH = 1.1 x 107]
Determine the equilibrium constant (kc) for the synthesis of PCl5 from PCl3 and Cl2 (PCl3 +Cl2 ⇌ PCl5).
Develop a Java program to allow computation of student marks in Eng, Math, Chem, Geo, and Physics. The teacher can enter marks for any number of students. He/she can press ‘E’ on the keyboard to stop entering marks. All marks should be stored in an array. When teacher presses E, the program computes and displays total marks, average, highest mark and lowest mark for each student. Use appropriate math functions for average, highest mark, lowest mark, a function which will be called every time the teacher needs to continue putting in marks, and control structures to guide the flow of the program.
Part 3: KNN
- Apply the kNN classifier to the Iris data (using 3 neighbors and unweighted distances).
- Output the classification report and confusion matrix and submit a screenshot of the result (1 mark).
Once an opportunity has been identified,defined and assessed as realistic and objective,the availability of resources needs to be evaluated. what is the next step in the entrepreneurial process?
Employment equity is the notion that.
One end of a copper poker is placed in a fire with temperature of 600°C, while the other end is kept at room temperature (25°). The poker is 1,5 m long and has a radius of 3 x 10-3 m.
A silver voltmeter,copper voltameter and oxygen voltameter are connected in series. Given that 4.32g of silver is deposited during the electrolytic process, determine(I) the mass of copper deposited(ii) the volume of oxygen liberated (Ag=108, Cu=64, O=16, G.M.V=22.4dm³
