Formula

Click For Summary

The discussion revolves around verifying the correctness of a formula used for calculating electrical parameters in a circuit involving a coil, capacitor, and resistor. The user presents a formula for frequency and equations for potential difference (P.d) across each component. They also calculate the current based on the total voltage and the potential differences. The community is asked to provide feedback on the accuracy of these calculations. The inquiry seeks clarity on the application of the formulas in the context of the given circuit.

Please see question at . . . . . .http://www.flickr.com/photos/37144556@N07/3475560721/sizes/o/

(B) f = 1 / (2.pi. square root of [ L.C ] )

(C)

(1)P.d across coil = 2.pi.f. (0.32)

(2) P.d across capacitor = 2.pi.fr.(0.5 x 10^-6)

(3) P.d across resistor = 30v - (1) - (2)

(ii) Current = 30/60

Is this correct??

any ideas?

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
