Three blocks are connected by an inextensible string as shown in figure, on a horizontal frictionless table and pulled to right with a force \(F\) \(=60 \mathrm{~N}\). If \(\mathrm{m}_1=10 \mathrm{~kg}, \mathrm{~m}_2=20 \mathrm{~kg}\) and \(\mathrm{m}_3=30 \mathrm{~kg}\), then tension \(\mathrm{T}_2\) in string is:
266265 Steam is passed into 22 g of water at \(20^{\circ} \mathrm{C}\). What mass of water will be present when the water is at \(90^{\circ} \mathrm{C}\) ? (latent heat of steam \(=2260 \mathrm{~J} \mathrm{~g}^{-1}\), specific heat of water \(=4.2 \mathrm{~J} \mathrm{~g}^{10} \mathrm{C}^{-1} \mathrm{y}\) :
