A pair of blocks, one more as massive than the other, are connected by a compressed spring. When the spring is released, the blocks fly apart. Compared to the heavier block, the lighter block accelerates at four times the rate of the heavier block. How many times more massive is the heavier block

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.
