A syringe is set up filled with air (mainly N2and O2) as shown in the diagram below. The cross-sectional area of the cylindrical syringe is 19.0 cm2. The initial pressure inside the syringe is Pi= 113 kPa and the height of the plunger above the bottom ishi= 27.4 cm. The syringe is made of a thin, transparent plastic. Give your answers to all parts of this question to three significant figures.
a) The syringe is compressed very quickly when the 5.00kg mass is placed on it. You take a photo of the syringe immediately after this takes place. What is the new height of the syringe?
b) After placing the 5.00 kg mass onto the syringe you wait for the syringe to return to thermal equilibrium with the surrounding laboratory. What is the height of the syringe now?
Two aluminum wires have the same resistance. If one has twice the length of the other, what is the ratio of the diameter of the longer wire to the diameter of the shorter wire
Power windmills turn in response to the force of high-speed drag. For a sphere moving through a fluid, the resistive force, FR is pro- portional to r2v2, where r is the radius of the sphere and v is the fluid speed.
A homogeneous ball with mass m = 1g and total charge q = 10^-3 C (uniformly distributed) is placed on a horizontal xy-plane. The ball starts rolling without slipping under the influence of a uniform electrostatic field E = (E,0,0) with E = 1 V/m. ..
