HURRY PLEASE Three resistors of 3.0 9, 8.0 2, and an unknown resistance are
connected in series across a 9.0-V battery. If the current through the unknown
resistance is measured to be 1 A, answer the following questions.
a. What is the current through the 3.0-Q resistor?
b. What is the equivalent resistance of the circuit?
c. What is the potential difference across the 3.0-0 resistor?

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.

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

This punnett square shows the cross between two pants. one parent has round seeds (rr). and the other parent has wrinkled seeds (rr) which best describes their offspring as shown in this cross?
