The magnitudes of the radii of curvature are 30.5 cm and 44.2 cm for the two faces of a biconcave lens. the glass has index of refraction 1.53 for violet light and 1.51 for red light. (a) for a very distant object, locate the image formed by violet light. (give your answer to two decimal places. indicate the position of the image relative to the lens with the sign of your answer.) (b) for a very distant object, locate the image formed by red light. (give your answer to two decimal places. indicate the position of the image relative to the lens with the sign of your answer.)

Matt is driving down 7th street. he drives 150 meters in 18 sec. assuming he doesn’t slow down or speed up, what is his speed?

Will you chech and finish these for me, because i am stumped with them.

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:
