A laser produces light of wavelength lamda and amplitude A. The light is directed through two slits that are separated by a small distance. On the other side of the slits is an interference pattern of alternating dark (black) and bright bands. What is the maximum amplitude of the waves in the interference pattern, and where does the maximum amplitude occur?
A 20.0- projectile is fired at an angle of 60.0 above the horizontal with a speed of 80.0 . At the highest point of its trajectory, the projectile explodes into two fragments with equal mass, one of which falls vertically with zero initial speed.
A car is driven east for a distance of 48km, then north for 32 km, and then in adirection 31°east of north for 25 km. Draw the vectordiagram and determine the total displacement of the car from itsstarting point.
A 3.0 microcoulomb point charge is placed in an external uniform electricfield of 1.6*10^4 N/C. At what distance from the charge is the netelectric field zero
A 1000g model rocket is resting horizontally at the top edge of a 40-m-high wall when it is accidentally bumped. How far from the base of the wall does the rocket land
Some simple elemental superconductors (called type I) are perfect diamagnets, meaning that their internal magnetic field exactly cancels the applied field. What is the susceptibility of such superconductors
A moving 4.50 kg block collides with a horizontal spring whose spring constant is 343 N/m. find the work done by the spring in bringing the block to rest
The pressure at the top of a tank of jet fuel is 180.6 kN/m^2. The depth of the liquid in the tank is 6.4 m. The density of the fuel is 825 kg/m^3. Compute the head of the liquid in m that corresponds to the absolute pressure at the bottom of the tan..
A steam engine takes in superheated steam at 290oC and discharges condensed steam from its cylinder at 70oC. If the useful power output of the engine is 210 kW, find how much heat does the engine discharge to its surroundings in 1.5 hour
A flight from Orlando, Florida to Atlanta, Georgia, covers 660 kilometer and heads at 29o west of north. Obtain the direction and magnitude of the Charleston-to-Atlanta leg of the flight
An electric field greater than about 3x10^6 V/m causes air to break down (electrons are removed from the atoms and then recombine, emitting light). Estimate the voltage between your finger and the doorknob
