A dielectric-filled parallel-plate capacitor has plate area A = 10.0cm2 , plate separation d = 5.00mmand dielectric constant k = 5.00. The capacitor is connected to a battery that creates a constant voltage V = 7.50V . Throughout the problem, use ?0 = 8.85×10?12C2/N?m2 .
A) Find the energy U1 of the dielectric-filled capacitor.
B) The dielectric plate is now slowly pulled out of the capacitor, which remains connected to the battery. Find the energy U2 of the capacitor at the moment when the capacitor is half-filled with the dielectric.
C) The capacitor is now disconnected from the battery, and the dielectric plate is slowly removed the rest of the way out of the capacitor. Find the new energy of the capacitor, U3.
D) In the process of removing the remaining portion of the dielectric from the disconnected capacitor, how much work W is done by the external agent acting on the dielectric?
A 1.00 kg beaker containing 2.0 kg of oil (density=916-kg/m3) rests on a platform scale. A 2.00 kg block of iron is suspended from a spring scale and is completely submerged in the oil.
Burning a pound of coal produces about 13,000 Btu of energy. How many megajoules of energy are produced by burning 4 pounds of coal?
Use graphical techniques to find out the direction of the dog’s resultant displacement vector. Give the direction of the resultant displacement in degrees (out of 360).
An aging coyote cannot run fast enough to catch a roadrunner. He purchases on eBay a set of jet-powered roller skates, which provide a constant horizontal acceleration of 15.0 m/s2. The coyote starts at rest 70.0 m from the edge of a cliff at the ins..
What is the energy density in the electric field at the surface of a 2.90-cm-diameter sphere charged to a potential of 1000V
The rocket moves for 3.00 s along its initial line of motion with an acceleration of 32.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile. Find out the maximum altitude reached by the rocket.
An oil drop whose mass is determined to be 3.3x10^-15 is held at rest between two large plates separated by 1cm while the potential difference between them is 340 V. How numerous excess electrons does this have here.
Helium (He), a monatomic gas, fills a 0.012 m3 container. The pressure of the gas is 6.90x 10^5 Pa. How long would a 0.25 hp engine have to run (1 hp = 746 W) to produce an amount of energy equal to internal energy of this gas.
a proton and an electron have the same kinetic energy upon entering a region of constant magnetic field. What is the ratio of the radii of their circular paths?
