The sudden conversion of water to water vapor causes a dramatic expansion that can rip apart shoes. water has density 1000 kg/m3 and requires 2256 kj/kg to be vaporized. if horizontal current lasts 2.14 ms and encounters water with resistivity 176 ω·m, length 13.2 cm, and vertical cross-sectional area 17.8 × 10-5 m2, what average current is required to vaporize the water?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
