Alow intensity light beam emitting about 10 photons/s impinges on a young's experiment in which the slits are spaced by a distance equal to 5 times the wavelength (300 nm). where will the first few photon counts be detected if a screen at distance 100 cm is covered with an array of photon counters?

a. the initial counts will appear in a single spot on the axis.
b. the initial counts will appear at a positions 0.035 cm above and below the axis.
c. the initial counts will appear at the first maxima on either side of the axis.
d. one cannot predict where the first counts appear but just the probability distribution.
e. the initial counts will appear in direct line with the two slits.

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
