In Fig. 13-57, identical blocks with identical masses m = 2.00 kg hang from strings of different lengths on a balance at Earth's surface, The strings have negligible mass and differ in length by h = 5.00 cm, Assume Earth is spherical with a uniform density ρ = 5.50 g/cm3. What is the difference in the weight of the blocks due to one being closer to Earth than the other?

- Problem 5: A painter (of mass 71 kg) needs to reach out from a scaffolding to paint the side of a building, so he lays a plank across two bars of the scaffolding, and puts a heavy bucket of mass 27 kg directly over one of the bars (see figure). You can assume the plank is massless, and is long enough to reach to the other building. L d If the bars are separated by a distance 1.5 m, how far, d, from the bar on the the right can the painter walk before the plank starts to fall? d= m 9 HOME sin() cos() tan() J ( ) 7 8 cotan() asin() acos() E 1시 신 4 atan() acotan() sinh() 5 6 7 * 1 2 3arrow_forwarda 5.0-kg block is taken to another planet that has the same mass as the Earth.

- a 300 kg cylinder that is horizontal. Three steel wires support the cylinder from a ceiling.Wires 1 and 3 are attached at the ends of the cylinder, and wire 2 is attached at the center. The wires each have a crosssectional area of 2.00 * 10-6 m2. Initially (before the cylinder was put in place) wires 1 and 3 were 2.0000 m long and wire 2 was 6.00 mm longer than that. Now (with the cylinder in place) all three wires have been stretched.What is the tension in (a) wire 1 and (b) wire 2?arrow_forwardA non-homogeneous bar is 50 cm long and its linear density is given by the function λ(x)=32 + 25x² , where x is the position of the bar from one end, where λ is given g/m (grams per meter). a) Draw a sketch of the bar and mark where on the bar its center of mass is locatedb) Calculate the total mass of the rod.arrow_forwardInternational computer communications are often carried by optical fibers in cables laid along the ocean floor.
