A certain telescope forms an image of part of a cluster of stars on a square silicon charge-coupled detector (CCD) chip 2.00 cm on each side. A star field is focused on the CCD when it is first turned on and its temperature is 20.0°C. The star field contains 5 342 stars scattered uniformly. To make the detector more sensitive, it is cooled to -100°C. How many star images then fit onto the chip? The average coefficient of linear expansion of silicon is 4.68×10 -6 (°C) -1.
A lunar lander is landing on the moon from 5.0 m above the surface, with a downward speed of 0.8 m/s. With the engine off, it is in free fall. find the speed of the lander just before it hits the surface
An air filled parallel plate capacitor has plates of area 5.0cm^2 each, separated by 0.30 mm with a dielectric of constant 3.4. What is the maximum charge on the capacitor
A woman on a bridge 71.0 m high sees a raft floating at a constant speed on the river below. She drops a stone from rest in an attempt to hit the raft. The stone is released when the raft has 6.60 m more to travel before passing under the bridge. ..
During the Millikan experiment used to determine the charge on the electron, a charged polystyrene microsphere is released in still air in a known vertical electric field, How many excess electrons are on the sphere
A laser is used in eye surgery to weld a detached retina back into place. The wavelength of the laser beam is 470 nm, while the power is 2.2 W. how many photons are emitted by the laser
The small mass m sliding without friction along a looped track is to remain on the track at all times, Calculate the magnitude of the normal force exerted by the track at the top of the loop
why to Assume charge 1 is located at the origin of x axis. A ball is thrown directly downward with an initial speed of 8.70 m/s, from a height of 30.6 m. After what time interval does it strike the ground.

Cliff and Will support the board at each end so that it is horizontal. A 52 kg boulder is placed on a 2.00 m long board at a point that is x = 1.45 m from Cliff. What force does Will apply to the board
The work function of a certain metal is ? = 3.05 eV. Determine the minimum frequency of light f0 for which photoelectrons are emitted from the metal. (Planck's constant is: h = 4.1357×10-15 eVs.)
Coulomb's Law gives us an expression for the electric field caused by a point charge with magnitude . Suppose we have several point charges. The electric field at a location is the vector sum of point charge contributions.
