Coherent light from the laser pointer shown here shines through two slits. The slits are 0.100 mm apart, and each slit is 0.025 mm wide. Light from the slits lands on a screen 4.0 m away.
Draw a true-scale graph showing the resulting power as a function of distance along the screen. Assume that the maximum power output of the laser point is split evenly between the two slits.
Your drawing must have the following properties:
o Quantitatively correct and actual-size horizontal axiso Correct vertical axis that is at least one-quarter page in sizeo Extensive enough to show the effects of both the size and separation of the slits.
A circular platform is supported by 8 identical steel wires. The platform and its uniformly distributed load has a total mass of 3.7 kg. The breaking stress of steel is 7.50 x 108 pascals.
What is this force in Newtons.

In the game of darts, the player stands with feet behind a line2.36 m from a dartboard, with the bull's-eye at eye level. Supposeyou lean across the line, release a dart at eye level 1.74 m from the board, and hit the bullseye.
Table contains the cosine frequency components of a Gaussian peak which has a full width at half-height of 1 sec. The unit height equation for such a Gaussian peak is exp[-4(ln 2)t^2] where t is time in sec. For each frequency component f with rel..
