A 3.00 µF and a 5.00 µF capacitor are connected in series across a 30.0 V battery. A 10.00 µF capacitor is then connected in parallel across the 3.00 µF capacitor. Determine the voltage across the 10.00 µF capacitor.
Suppose that .88 g of water condenses on a 75.0 g block of ironthat is initially at 22C. If the heat released during condensation goes only to warming the iron block, what is the final temperature( in C) of the iron block?
Assuming both air flows to be steady, inviscid and incompressible, and neglecting body forces and weight of the cylinder, determine the magnitude and direction of the net force acting on the cylinder plug. P=1.5x10^5 Pa, T=20 deg C.
Then the car slows down at a constant rate. Suppose that the total distance moved by your car during these two phases is 56.7 m when its initial speed is 82.0 km/h, and 24.4 m when the initial speed is 49.8 km/h.What is the magnitude of the decele
In the present experiment we will be preparing Nylon 66. We willreact 1,6-hexanediamine with an acid chloride prepared from adipicacid. The acid chloride called adipoyl chloride, will be prepared by reacting adipic acid with thionyl chloride.
