    Calculating Initial Mass for Nuclear Reactor Operation

    Homework Statement What initial mass of 23592U is required to operate a 350 MW reactor for 3 yrs? Assume 46% efficiency. Homework Equations I used Mass* C* efficiency as a decimal= power (e^-6) * time (in seconds) and got 800 as the mass, however, this was incorrect The Attempt at a...

    Calculating Time Needed for 1.0 mCi of 3215P to Deliver 36 Gy

    A 1.0 mCi source of 3215P (in NaHPO4), a β emitter, is implanted in a tumor where it is to administer 36 Gy. The half-life of 3215P is 14.3 days and 1 mCi delivers about 10 mGy/min. Approximately how long should the source remain implanted? I'm calculating 2.19 days but doing something wrong...

    Undergrad Is the Time Constant Affected by Changing Plate Distance in an RC Circuit?

    I'm not sure what I'm doing wrong though, because with that I'm getting a completely different answer. I realize its 63% until tmax. and the settings would be .5V. But how are you getting the other parts?

    Undergrad Calculating Time Constant in Parallel Plates: Keeping the Capacitor Constant

    How can a time constant, in parallel plates, be the original value without changing the capacitor?

    Undergrad Is the Time Constant Affected by Changing Plate Distance in an RC Circuit?

    If, by some means, the distance between the parallel plates of the capacitor is reduced to half of what it was before, would the time constant change? If yes, then what would be the new time constant?
