An RC circuit, hooked up to a battery as shown in the figure, starts with an uncharged capacitor. The resistance in the circuit is R = 784.0 Ω the capacitor has capacitance of C = 68.0 μF and the battery maintains the emf of ε = 32.0 V. The switch is closed at time t = 0.0 s and the capacitor begins to charge.
What is the time constant for this circuit?

If engineering graduates’ average (starting) salaries were approximately $60,000 for the class of 2010. What will the average starting salaries amount be in 2020, if engineering starting salaries increase at the rate of (a) 2% per year, and (b) twice that rate or 4% per year?

Before shopping on-line became very popular with consumers a few years ago, 10% of retail outlets in Greece closed their doors each year (i.e., went out of business). A random sample of 200 retail outlets across Greece which were open at the beginning of 2015 were randomly selected for a study. At the end of 2015, 25 or these outlets were no longer open. At the .10 level of significance, is there sufficient evidence that the proportion of all Grecian retail outlets that closed in 2019 is greater than the proportion that closed before shopping on-line became very popular? In answering this question, complete the following in the spaces provided (including diagrams):

After reading Chapter 6 on Lean Systems, one obvious take away is that a huge component of successful Lean implementation is teamwork. A case could be made that Lean systems work better in some cultures than in others, depending how that culture values the collective. In essence, it comes down to Teamwork vs. Autonomy. For example, you could make a statement that Toyota is very good at Lean systems because Japanese culture traditionally values the collective over the individual. Think about a culture that you are familiar with and give your opinion on if you think that a Lean System would fair well there and why. A culture could be from a company, school, city, state, country, region, etc. I'm interested in what you think and your opinion here, so have some fun with the topic while being sensitive to all cultures and viewpoints.

A circuit is constructed with four resistors, one capacitor, one battery and a switch as shown. The values for the resistors are: R1 = R2 = 32 Ω, R3 = 90 Ω and R4 = 89 Ω. The capacitance is C = 85 μF and the battery voltage is V = 12 V. The positive terminal of the battery is indicated with a + sign.

1) The switch has been open for a long time when at time t = 0, the switch is closed. What is I4(0), the magnitude of the current through the resistor R4 just after the switch is closed?
2) What is Q(∞), the charge on the capacitor after the switch has been closed for a very long time?
3) After the switch has been closed for a very long time, it is then opened. What is Q(topen), the charge on the capacitor at a time topen = 713 μs after the switch was opened?
4) What is IC,max(closed), the current that flows through the capacitor whose magnitude is maximum during the time when the switch is closed? A positive value for the current is defined to be in the direction of the arrow shown.
5) What is IC,max(open), the current that flows through the capacitor whose magnitude is maximum during the time when the switch is open? A positive value for the current is defined to be in the direction of the arrow shown.

Collective bargaining is enshrined in ILO conventions that provides for freedom of association and right to collective bargaining.
Article 4 of ILO Convention 98 states that Measures appropriate to national conditions shall be taken, where necessary, to encourage and promote the full development and utilisation of machinery for voluntary negotiation between employers or employers' organisations and workers' organisations, with a view to the regulation of terms and conditions of employment by means of collective agreements.
The Task In your initial or first posting you should identify two measures that were taken and state why you believe that these measures taken by your country encourage and promote negotiation and collective agreements.
In your second posting, you need to respond to any of your colleague by adding substantially or refuting their body of work In your response, include the links to the websites and cite sources used in your research

Miller Mining has $30 million in land value and $15 in mortgage bonds issued on the property. These bonds were originally issued at par ($1000), but are now selling today (April, 2010) based on a 7.75%, compounded semi-annually, market rate of return. The bonds have a stated interest rate of 8% and mature on January 1, 2020. The bonds pay interest semi-annually on July 1 and January 1 each year. Suppose that an investor buys a $1,000 face value bond on April 1, 2010. What dollar amount will the investor pay to the seller on April 1?
