A company purchased a machine on January 1 of the current year for $750,000. Calculate the annual depreciation expense for each year of the machine's life (estimated at 5 years or 20,000 hours, with a salvage value of $75,000). During the machine's 5-year life its hour...

When a resistor is connected across the terminals of an ac generator (112 V) that has a fixed frequency, there is a current of 0.500 A in the resistor. When an inductor is connected across the terminals of this same generator, there is a current of 0.400 A in the inductor. Whe...

Planets A, B and C orbit a certain star once every 3, 7, and 18 months respectively. If the three planets are now in the same straight line, what is the smallest number of months that must pass before they line up again?
PHY: To AJAYB, follow up on previous response
First, I'd like to thank you for your response to my question. However, I had some follow up questions on your response from Saturday, July 28, 2012 at 8:27am. If you could take a look at that post and get back to me, it would be greatly appreciated.
Physics- Repost (Answer did not make sense)
Thanks for your response, but I have a few questions. For part B, why is full battery voltage 6V, and not 12V? For part C, my question is once again about using 6V in the calculation for finding q0, as well as units. Using 6V, qo= 54 uC? For the time constant, I plugged in 12m...

I plugged the #'s into that site you supplied, but I still get my answer of 0.012 seconds, not the 1.2E-5 seconds you put?
