To loosen a frozen valve, a force F with a magnitude of 70 lb is appliedto the handle of the valve. Knowing that θ = 25°, Mx = –61 lb·ft, andMz = –43 lb·ft, determine ϕ and d.

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.

Nps pollution is caused by rainfall or snowmelt moving over and through the ground. nonpoint source pollution can include: excess fertilizers, herbicides and insecticides from agricultural lands and residential areas. oil, grease and toxic chemicals from urban runoff and energy production
