Problem 10 the projector in kimpel 102 is about 7m = 700cm from the screen at the front of the classroom. from the size of the projector enclosure, the object in the projector cannot be more than 5cm from the projector lens. what is the approximate focal length of the lens in the projector? select one of the following: 3 (a) 4.96cm (b) 5.04cm (c) 30.3cm (d) 350cm (e) 700cm

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
