An annular charge with radius R and an evenly distributed positive charge is studied. At what point (expressed in terms of R) is the Electric field maximum?
Zales Jeweller uses rubies and sapphires to produce two types of rings. A type 1 ring requires two rubies, three sapphires and one hour of jeweller’s labour time. A type 2 ring requires three rubies, two sapphires and two hours of jeweller’s labour time. Each type 1 ring sells for R1 200 and each type 2 ring sells for R1 500. All rings produced by Zales can be sold. At present, Zales has 100 rubies, 120 sapphires and 70 hours...
An ostomy clinic uses barrier rings on its patients to help prevent ostomy-related leaks. Last year, the clinic used 6,200 units of barrier rings. Each unit costs $50.94 and the annual holding cost per unit is $10. It costs $200 for each order placed and lead time for delivery is five days. If the annual holding costs for rings was able to be decreased to $5.00 per unit, what would happen to the economic order quantity? It would stay the...
Two identical nano-particles each contain 10 atoms. One nano-particle is on top of the other, and they are in contact, so energy can flow between them. The combined energy of both nano-particles is ten quanta. What is the probability that at a given instant, all the energy is in the top nano-particle?
An electric doorbell uses an electromagnet to pull on a steel hammer that rings the bell. The electromagnet has inductance 65.0 mH and resistance 7.86 Ω (meaning you can treat it as an LR circuit with the inductance in series with the resistance). It operates from a 6.00-V source. How long does it take for the current in the electromagnet to reach 0.700 A?

A type 2 ring requires three rubies, two sapphires and two hours of jeweller's labour time. Each type 1 ring sells for R1200 and each type 2 ring sells for R1500. All rings produced by Zales can be sold. At present, Zales has 100 rubies, 120 sapphires and 70 hours of jeweller's...
Psychology is defined as a science but it falls under "social sciences". What this means is that is studies humans and society. Psychology uses empirical methods to research and study behavior, humans, the mind, etc. If psychology did not use these methods, could it still be considered a science?
Discuss your understanding of science. What is science? What does science show us – and what does it not show us? Identify or design your own research question and state what the independent and dependent variables would be (e.g., I am interested in whether chocolate consumption decreases anxiety. Chocolate would be the ____ variable and anxiety would be the _____ variable). Students are required to: 1) respond to the original discussion prompt provided and 2) respond to at least one...
