A cylindrical tank with a large diameter is filled with water to a depth D = 0.310 m. A hole of cross-sectional area A = 7.51 cm2 in the bottom of the tank allows water to drain out.
(a) What is the rate at which water flows out, in cubic meters per second?
(b) At what distance below the bottom of the tank is the cross-sectional area of the stream equal to one-half the area of the hole?
Calculate for the capacitance, the charge of plate, and magnitude of electric field between the plates for a capacitor whose plates are 11 mm apart are 2.00 m-2 in area and being connected to a source with potential difference of 270V.
A 5 uF capacitor is initially charged to a potential of 16 V. It is then connected in series with a 3.75 mH inductor.
110 grams of boiling water (temperature 100° C, heat capacity 4.20 J/gram/K) are poured into an aluminum pan whose mass is 1000 grams and initial temperature 24° C (the heat capacity of aluminum is 0.9 J/gram/K).
All distant galaxies are moving away from us. Describe why this does not imply that we are at the center of universe.
As a crude model for lightning, consider the ground to be one plate of a parallel-plate capacitor and a cloud at an altitude of 510m to be the other plate.
