Claudia goes bungee jumping. she has a mass of 51 kg.

a. the bungee cord will stretch 5 m when 200 n of force is applied to it. what is the spring constant of the bungee cord?

b. after her jump, claudia hangs from the cord motionless. how stretched is the bungee cord past its natural length?

c. the maximum force the bungee cord can handle without breaking is 15,000 n. how far would you have to stretch it to get it to break?

How would a small bar magnet be oriented when placed at position x?

Juliette sets the initial velocity to +10 m/s, the acceleration to zero, and clicks “start.” how can shakina describe the subsequent motion of the car juliette controls?

People with normal vision cannot focus their eyes underwater if they aren't wearing a face mask or goggles and there is water in contact with their eyes. 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.with the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 2.05cm in front of the eye.)
