Question Please show all steps and explanations. A filamentary current of 10A is directed in from infinity to the origin on the positive x axis and then back to infinity along the positive y axis. Find H(0,0,1).

complete table 21-1 k resistor ilor (value to be determined by student) SUMMARY OF THEORY: If a resistor is connected across a sine-wave generator, a current flows that is in phase with the applied with the voltage. This is illustrated in Figure 21-1. Note that the current and voltage have exactly the voltage. If, instead of a resistor, we connect a capacitor across the generator, the current is not in phase same frequency, but the current is leading the voltage by V4 cycle. Maximum current Current Voltage Voltage charge is maximum Figure 21-1 Current and voltage relationship in a capacitor. Current in the capacitor is directly proportional to the capacitance and the rate of change of voltage. The largest current occurs when the voltage change is a maximum. If the capacitance is increased or the frequency is increased, there will be more current. This is why a capacitor is sometimes thought of as a high-frequency short. Reactance is the opposition to ac current and is measured in ohms, like resistance. Capacitive reactance is written with the symbol Xc It can be defined as Xc - zato 2m fc where f is the generator frequency in hertz and C is the capacitance in farads. 205 Vc=1Xc PROCEDURE: 1. Obtain two capacitors with the values shown in Table 21-1. If you have a capacitance bridge available, measure their capacitance and record in Table 21-1; otherwise record the listed value at the capacitors. Measure and record the value of resistor R. 2. Set up the circuit shown in Figure 21-2. Set the function generator for a 1.0 kHz sine wave with a 1.0 Vrms output. Measure the rms voltage with your DMM while it is connected to the circuit. Check the frequency and voltage with the oscilloscope.

Shelly and Kelly Macdonald met up with Sarah and Tara MacNeill to go fishing in Cape Breton. They found two pools in a stream containing speckled trout (assume equal variance), with the Macdonalds at one pool and the MacNeills at the other, and at the end of the day each team had caught (and released unharmed) 5 fish. For each fish they recorded the length and weight, and the data on length (in cm) is summarized below (Give the answers to 2 places past decimal) Team Macdonald MacNeill Mean 19 Std.Dev 1.6 21.24 2 a.)

(a) Find his optimal consumption bundle. (b) What happens when the when the income rises to B=800, other factors remaining constant?

Question B2 Manufacturer A manufacturing company produces products. The following product information is stored: product name, product ID and quantity on hand. These products are made up of many components. Each component can be supplied by one or more suppliers. The following component information is kept: component ID, name, description, suppliers who supply them, and products in which they are used. Use Figure B.1 for this exercise. Create an ERD to show how you would track this information. Show entity names, primary keys, attributes for each entity, relationships between the entities and cardinality. Assumptions A supplier can exist without providing components. • A component does not have to be associated with a supplier. A component does not have to be associated with a product. Not all components are used in products. A product cannot exist without components.
