(1) Braking power [kW, hP] (2) Torque [Nm] (3) Non-output [kW/cm2] (4) Output per

Below is an example of a well-written letter. Analyze it with respect to traits of technical writing and Seven Cs of communication. Identify the traits and explain how are they present in the letter. For example, if you think its language is concise, give reason for your answer. Sally Kate 39 Hopkins Street, California October 7, 2020 Kelly Wing

The first two spin orbitals for the hydrogen atom are 1 Pr0o(r,0, ,0) V4n a, ,32 and 1. 1(r,0,4,0) e ao V4n a2 show that they are orthogonal, assuming that the spatial and spin parts of the wave function are independent. Show the process for credits.
