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.

If a balloon is taken outside on a very cold day, what will occur?

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
