A uniform beam is 2m long, has a mass 100 kg, and it is supported at its center by a triangular support. the beam is balanced. Mass m1 is 25 kg mass m2 is 10 kg. a. If the distance d is 0.25 m what will the value of mass mx be such that the beam is balanced? b. If you were to remove mass mx and moved the support instead. What will that distance L be such that the beam remains balanced, see figure below

In a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina. what should be the radius of curvature of the cornea such that the image of an object 40.0 cm from the cornea’s vertex is focused on the retina?
