2. A vector A has a magnitude of 30 m at an angle of 225° with respect to the positive x-axis. If we add a vector B, it is found that the resultant is along the positive x-axis and has a magnitude of 13 m. What are the components of vector B and its direction?

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
