Real assembly languages are similar to the simplified one used in this activity, though the way they process instructions and their instruction sets may vary greatly. for example, most assembly languages give programmers the ability to manipulate multiple registers, specifying which registers to work with, or they grant access to data outside of the cpu. what do you think the challenges of programming in an assembly language instead of a high level language like scratch would be

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
