A crate with dimension 12 x 10 x 4in and a mass of 120lbs slides on an inclined plane of dimension 80 x 10 x 3in. Answer following questions: 1. Model the system in ADAMS without friction and compare your result with the analytical solution 2. Model the system in ADAMS with friction coefficients, μs=0.4 and μd= 0.3 and and find the minimum inclination that will ensure that a crate slides off an inclined plane. Find the value of the crate's constant acceleration. compare and verify your result with the analytical solution. 3. For previous part, simulate the model for an end time of 0.5 seconds and plot the create acceleration vs. time. Show all the calculations and results clearly

Aprotein molecule in an electrophoresis gel has a negative charge. the exact charge depends on the ph of the solution, but 30 excess electrons is typical. what is the magnitude of the electric force on a protein with this charge in a 1600n/c electric field? write in two significant numbers, and also in newton

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.)
