Consider a resistor with color code “orange blue brown gold” and a measured value of 370 ω. determine the following: nominal value, tolerance, % error, and the probability of another resistor from the same manufacturing batch having a value closer to nominal than this one. use matlab or excel to evaluate the erf function.

Which of the following is considered to be a vector?               a.  temperature    b.  velocity    c.  time    d.  mass

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u.s. legal proceeding.)
