← A uniform spring of force constant 120 N/m is cut into two pieces whose lengths are in the ratio 1 : 2. A block of mass 0.60 kg lies on a smooth table between two walls, with the short piece joining it to one wall and the long piece to the other. Both pieces have their natural lengths when the block is at rest. What is the angular frequency of small oscillations of the block? Give the answer in rad/s.A container holds a mixture of 1.0 mol of helium (4 g/mol) and 1.0 mol of oxygen (32 g/mol), well mixed, at 300 K. Treat both as ideal gases, with R = 8.314 J/(mol K). What is the speed of sound in the mixture? →
