Two thin parallel slits that are 19.5 latex: \muμm apart are illuminated by a laser beam of wavelength 585 nm. the interference pattern is observed on a very distant large screen. what it the total number of bright fringes (those indicating complete constructive interference), including the central fringe and those on both sides of it? solve this problem without calculating the angles! (hint: what is the largest that latex: \sin\thetasin ⁡ θ can be? what does this tell you is the largest value of m? )

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:
