Mountain pull. a large mountain can slightly affect the direction of ""down"" as determined by a plumb line. assume that we can model a mountain as a sphere of radius r = 2.00 km and density (mass per unit volume) 2.6 × 103 kg/m3. assume also that we hang a 0.750m plumb line at a distance of 3r from the sphere's center and such that the sphere pulls horizontally on th

Janelle made a hypothesis bout the uneven temperatures inside her house during winter. she believes that 50% of the ducts are blocked and she plans to investigate. if she wants to prove her hypothesis using scientific processes what should she do next?

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ

Which of the following is an example of units for speed
