One half mole of ideal gas is taken front state a to state c. (a go down to b and b to c in a line) a pressure is 4.0x10^5, V is .002m^3, b pressure is 2.0x10^5, V is .003m^3 and c pressure is 2.0x10^5 V is .004m^3. A) Calculate the final temppera
a) How wide must this oven be so that it will contain six nodal planes of the microwave disturbance (including the nodal plane at each walls) along its width in the standing wave pattern? b) What is the frequency of these microwaves?
A child's water pistol shoots water through a 1.0 mm -diameter hole. If the pistol is fired horizontally 80 cm above the ground, a squirt hits the ground 1.2m away. What is volume flow rate during the squirt? Ignore air resistance. Answer in mL/s
An infinite line charge of uniform linear charge density = -1.1 C/m lies parallel to the y axis at x = -1 m. A point charge of 2.1 C is located at x = 2.0 m, y = 3.0 m. Find the x- and y-components of the electric field at x = 3.0 m, y = 2.5 m.
A singly ionized helium atom (He+) has only one electron in orbit about the nuclues. What is the radius of the ion when it is in the excited state defined by n=3?
A longitudinal standing wave is established in a tube open at one end only. In air, the fundamental frequency is 110 Hz. What is the frequency of the 3rd harmonic when helium fills the tube? Take the speed of sound in helium to be three times as g
