How would one go about proving that the magnitude of A equals the square root of x squared plus y squared plus z squared ( |A| = rad/(x^+y^+z^) )? ✅ Answers ? Favorite Answer it’s just pythagoras’ theorem. have to use it twice: let the diagonal = f f^=x^+y^ then [lAl]^= f^+z^ [lAl]^= x^+y^+z^ lAl … Read more
The slope has a physical meaning. Iti is called the coefficient of friction , greek symbol mu is an upside down u. the coefficient of friction essentially tells you howw much two surfaces stick together. Explain why the coefficient of friction does not have units The coefficient of friction is a pure number without units … Read more
a man runs at a velocity of . m/s for min. when he runs up a hill, he slows at a rate of . m/s^ for . s and comes to a stop. how far did he run? Break the problem up into two segments. The contant velocity portion and then the hill portion. Then … Read more
what is the total resistance of this circuit? and what is the total current thru the v battery? First, solve the resistance of the parallel resistors and then add that to the series resistor to get total resistance: /R(p) = /R + /R = / + / = / + / = / Thus R(p) … Read more
Answers Favorite Answer I’m just guessing because I don’t have your course outlines that you’ll get plenty of trig in your geometry course. Schaum’s is strictly secondary reference, not a primary textbook. As the series implies, these are outlines of the subjects. I use their Quantum outline as reference, but I’ve taken quantum physics at … Read more
