Find the charge on the capacitor in an LRC-series circuit at t = 0.04 s
when
L = 0.05 h,

R = 3 Ω,

C = 0.02 f,

E(t) = 0 V,

q(0) = 3 C,
and
i(0) = 0 A.

Determine the first time at which the charge on the capacitor is equal to zero. (Round your answer to four decimal places.)

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
