In the uniform circular motion lab, the period for a complete cycle was measured for a mass spun at a constant speed about a fixed radius and with a constant centripetal force fc. If the radius was increased in increments while the force and mass remained constant, the period of a complete cycle is expected to? A. Increase B. Remain the same C. Decrease
We did a lab in which we discovered how increasing the length of a nichrome wire affects the amount of current and found that there was an inverse relationship. We used an ammeter, one battery, and measured varied lengths of nichrome wire from 5-100 cm. What are some possible sources of random or systemic experimental error in this experiment?
Lab Homework - Force on a Current-Carrying Wire This homework will be due when you come to lab the week of November 4. A horseshoe magnet, with its north and south poles indicated, is shown in the figure below. Between the poles of the magnet is a wire perpendicular to the page, with current out of the page. a) Draw magnetic field lines for the magnet. Explain why you drew the field lines the way you did. b) If there...

You have two wires connected end-to-end (in series). Wire 1 is copper and wire 2 is made from a “special” carbon conductor. Wire 1 has a resistance of 0.215 Ω/ft. and is 500 ft. long. Wire 2 has a resistance of 0.141 Ω/ft. and is 700 ft. long. Both of these resistances are measured at 20°C. If the ambient temperature is 99°F, what is the wire’s total series resistance? (FROM AN OLD F.E. EXAM) A reminder that temperatures must be...
Elaina performs the copper cycle lab beginning with 10.00 mL of a 1.65 M Cu(NO), solution. After drying to constant mass, she recovers 0.996 g of copper metal. What is the theoretical yield of copper in grams? theoretical yield: What is the actual yield of copper in grams? actual yield: What is the percent yield of copper? percent yield:
7 points it, in the equilibrium constant lab, you measured a molar abosorptivity for FelSCN to be 5,000M 1 when it was actually 4.000 M 1 would this affect the value of your equilibrium constant? Explain your answer. 12pt Paragraph BLU AI EI**EE
Pre-Lab Q2: Consider the equation you will use to calculate the period of your pendulum. For each scenario below, determine how an error in your length measurement (L) would affect your predicted period value (T). a. SCENARIO 1: You measured the pendulum length (L) to be LARGER than the actual value. As a result your predicted period (T) will be: i. LARGER than the actual value. ii. SMALLER than the actual value. b. SCENARIO 2: You measured the pendulum length...

An ideal Otto cycle has a compression ratio of 8. At the beginning of the transferred compression process, air is at 95 kPa and 27-degree C, and 750 kJ/kg of heat is to air during the constant-volume heat-addition process. Considering the variation of specific heats with temperature (Table A-17), determine (a) the pressure and temperature at the end of the heat addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the...
