There are two telescopes observing at night. The first telescope is 0.3m and has a focal ratio of f/8. The second telescope has a focal ratio of f/4 and is 30m in diameter. They each have an identical CCD camera whose pixels are 25 microns on a side. How much energy will be accumulated in a single pixel in a 100s exposure?
Note: Object being observed has an apparent brightness of 1.0*10^-7 W m^-2 and has an angular diameter of 15 arcsec.
Consider a spacecraft in an elliptical orbit around the Earth.At the perigee it is 400 km away from the earth's surface; What is the period of the spacecraft's orbit
Relationships between wavelength, frequency and speed.
A disk-shaped merry-go-round of radius 3.02 m and mass 159 kg rotates freely with an angular speed of 0.635 rev/s. A 54.1-kg person running tangential to the rim of the merry-go-round at 3.07 m/s jumps onto its rim and holds on. Before jumping on the..

iron atoms have been detected in the sun's outer atmosphere, some with many of their electrons stripped away. What is the net electric charge(in coulombs) of an iron atom with 26 protons and 7 electrons? Be sure to include the algebraic sign (+ or..
n air-filled spherical capacitor is constructed with inner and outer shell radii of 7.00 and 14.0 cm, respectively. Calculate the capacitance of the device
Determine the maximun wavelength of incident radiation that can be used to remove the remaining electron from a singly ionized helium atom He+ (z= 2)
An electron and a proton are initially very far apart (effectivelyan infinite distance apart). They are then brought together to forma hydrogen atom, in which the electron orbits the proton at anaverage distance of 5.39*10-11 m.
