1. Conduct research to identify claims made about the effects that certain frequencies of EMR have when absorbed by matter. Find two examples from published sources. Write brief descriptions of your two examples. (5 points) A) What parts of the EM spectrum are being used? Compare them in terms of wavelength, frequency, and energy.

B) What cause-and-effect relationships are being suggested or predicted based on smaller-scale mechanisms in the systems described by the claims?

C) State whether each claim appears to be valid or false. Give a reason to support each of your evaluations.

f=gm1m2/d^2 it d

f is force g is gravitaiton constant, m1 is mass of first object, m2 is mass of second object. d is distance between two object

most voltage drop calculators want the distance between the source and destination. then internally, they double it so both the source and return wires are calculated. but you need to know which distance the calculator uses so you're not half of what you should be or double what you should be.

most circuit breakers will not take a #6 directly, so the electrician will have to splice on a smaller pigtail. you also have to upsize the grounding wire when you upsized the ungrounded (hot) wire (see note in 250.122). this will preclude using most cable assemblies, as a cable with #6 copper will most likely only have a #10 grounding conductor. you need a #6 grounding conductor if the circuit is 20a. a #8 cable is no better, as it will have a #10 grounding conductor too. but most 20a breakers will take a #8 directly.

in your related post, you didn't say what type of load this is. if it is a light or heater, voltage drop won't be a big issue. if this is a motor, the current needs are huge at startup and the voltage drop can pose a problem. if this is a motor, knowing if the motor is under much load during startup will answer the voltage drop effect (a saw is easier to start than a compressor).

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

the components of a vector are the parts of the vectors that are to each other.
