Find the two new orbits. (I initially thought the orbits would be the same as the original except one piece would be going in the opposite direction, however my professor said that it was incorrect)
Helium gas fills in a well-insulated cylinder fitted with a piston at 295K and 1 atm. The piston is moved very slowly (adiabatic expansion) so that the volume increases to four times its original vo
After the two come into into thermal equilibrium, what is the temperature of the water? If a second identical ice cube is added, what is the temperature of the water? The specific heat of water is 4
A 5-µF capacitor is charged to 30 V and is then connected across a 10-µH inductor. The frequency of oscillation of the energy stored in the electric field of the capacitor and the magnet
A 0.072m X 0.045 m steel beam of length 3.7m is heated from 293Kelvin to 372Kelvin. What is the new length of the beam? What is the strain in the beam?
A 5-µF capacitor is charged to 30 V and is then connected across a 10-µH inductor. The maximum value of the current in this circuit is
A 5-µF capacitor is charged to 30 V and is then connected across a 10-µH inductor. The maximum value of the energy stored in the electric field of the capacitor is:
A- Explain, in terms of the microscopic structure of matter, why materials expand when heated.
A cubical block of side length L has a density DC and floats in a liquid of density DL. The answers should be in terms of these parameters and constants. a) Determine the fraction of the volume of t
During an earthquake, the top of a building oscillates with an amplitude of 30cm at 1.5Hz. Part A: What is the magnitude of the maximum displacement from the equilibrium of the top of the building? (i
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 small earthquake starts a lamppost vibrating back and forth. The amplitude of vibration of the top of the lampost is 6.0cm at the moment the quake stops, and 7.8s later it is 2.2cm. Part A: What
Finally, sketch a fourth wave of amplitude 2 cm in phase with the first two waves. Use the sketches to aid answering the following questions.(a) What is the amplitude of the sum of these waves?
The eyepiece of a microscope has a focal length of 1.25 cm and the objective lens focal length is 1.49 cm. (a) If the tube length is 22.0 cm, what is the angular magnification of the microscope?
On the screen, the red light with a wavelength of 688 nm is separated from the violet light with a wavelength of 391 nm by 6.60 mm. What is the separation of the two slits?
An object 5.00 mm tall is placed 6.00 cm to the left of a converging lens of focal length 20.0 cm. a) How far away from the lens is the image formed?
Will the house remain comfortable? Suppose that comfortable temperature is 18 degrees celcius.
Find an expression for the value of capacitance C if the charging energy associated with the coulomb blockade for the capacitor is the same as Eo.
What is the minimum potential difference that must be applied to an X-ray tube to knock a K-shell electron completely out of an atom in a copper (Z = 29) target? Use the Bohr model as needed.
He-Ne lasers are often used in physics demonstrations. They produce light of wavelength 633 nm and a power of 0.700 mW spread over a cylindrical beam 1.20 mm in diameter (although these quantities
A building stands on the shore, and the laser beam hits a target at the top of the building. The goal is to find the height of the target above sea level.Find the angle of incidence of the beam stri
Rotation in the Milky Way: as I mentioned the rotation speed of the sun around the Milky Way center is approximately 200 km/s (actually to be precise, it's 220 km/s), and that it takes the sun aroun
What is the energy range (in joules and in eV) of photons in the visible spectrum, of wavelength 400 nm to 750 nm? (Enter your answers with the lowest energy first.)
About 0.1 eV is required to break a "hydrogen bond" in a protein molecule. Calculate the minimum frequency and maximum wavelength of a photon that can accomplish this.
