2\u00a0<\/sub>isothermally, \n \n <\/p>\nAnswer 9. \nMaterial A is stronger than material B because it can withstand more load without breaking for material A, the break-even point (D) is higher.<\/p>\n
Answer 10. \nThe thermal conductivity of brass tumbler is larger than a wooden tray. Hence a brass tumbler feels much colder than a wooden tray.<\/p>\n
Answer 11. \na.Hydrostatic paradox. \nb. Pressure at the same height is the same.<\/p>\n
Answer 12. \n \nb. 3<\/p>\n
Answer 13. \n1. Amplitude should be small. \n2. The period of simple pendulum \\(T=2\\pi \\sqrt { \\frac { 1 }{ g } }\\) \nWhen a lift is moving down with an acceleration g\/3. \n <\/p>\n
Answer 14. \na. The passenger experiences a decrease in weight. \n \nb. The passenger experiences weightlessness W’ = m (g – g) = 0<\/p>\n
Answer 15. \na. Material A is more elastic. Because the strain of material A is smaller than that other and slope of A is more. Soan extension of A will be less than B and C. When they are subjected to same reforming force F. \n <\/p>\n
Answer 16. \na. Hooke\u2019s law. Hooke\u2019s law states that when elastic limit stress is directly proportional to strain. \n <\/p>\n
Answer 17. \na. Heat can be given to gas in two ways. \n1. By keeping the pressure constant. \n2. By keeping volume constant. In (1) gas expands, additional heat is needed to work. \n <\/p>\n
Answer 18. \na. Centre of a mass of a rigid body in the point where the whole mass of the body is assumed to be concentrated. \n <\/p>\n
Answer 19. \n \n <\/p>\n
Answer 20. \n <\/p>\n
Answer 21. \na. Newton\u2019s 1st Law of motion. The law states that \u201c everybody continues in its state of rest or of uniform motion in a straight line unless compelled by some external unbalanced force to change that state\u201d, \nb. The law states that \u201c If no external force acts on a system of several particles, the total linear momentum of the system remains constant\u201d.<\/p>\n
Answer 22. \na. The constant speed of the object falling through a viscous medium is called terminal velocity. The vicious force, F = 6xr|rv Considering the motion of the body, viscous force = apparent weight of the object in the fluid. where 5 is the density of the material of the solid and a that of the fluid. \n \nb.Rain drop falling under gravity is acted upon by weight, upthrust and viscous force. Hence it attains constant velocity.<\/p>\n
Answer 23. \na. Heat energy into mechanical energy. \nb. Isothermal expansion AB Adiabatic expansion BC Isothermal compression CD Adiabatic compression DA \n \nd. \n1. Gas molecules randomly move all the time and collide with each other and with walls of a container. \n2. Size of molecules is negligible compared to the average distance between molecules. \n3. Molecules are rigid spheres with no attraction or repulsion between themselves or container and so, all the internal energy is kinetic. \n4. A collision between molecules and wall are elastic. In between collisions they move in straight lines with uniform velocity. Time of collision is very small compared to time available for free motion.<\/p>\n
Answer 24. \na. Obtuse or \u03b8 > 90\u00b0 \n \nThe capillary action is a result of both adhesion and surface tension. If a capillary tube is held vertical in a liquid which has a concave meniscus. There always exists an excess pressure equal to 2s\/R on the concave side of liquid are interphase. Where \u2018S\u2019 is the surface tension and R is the radius of curvature of a meniscus. Pressure just below the meniscus is p 2s\/R, where P is the atmospheric pressure. The pressure outside the tube at a level of the meniscus is the atmospheric pressure’P\u2019. Since the pressure at points in the same level of liquid must be the same, the liquid is pushed up in the tube to the height \u2018h\u2019 as shown in fig(a). In this position, the pressure of liquids column of height \u2018h\u2019 becomes equal to 2s\/R.\u00a0\u2234 \\(hpg=\\frac { 2s }{ R }\\) where p is the density and \u2018g\u2019 is an acceleration due to gravity. \nFrom fig (b) \n \n \nl = 2h or length increases.<\/p>\n
Answer 25. \na. Just as inertia resists translatory motion, when a rigid body rotates about an axis, there is a tendency to resist changes in uniform rotational motion. Moment of inertia resists change in rotational motion of the body. \nb. Moment of inertia of a rigid body depends on the mass of particles and the distribution of particles about the axis of rotation, size, and shape. \n <\/p>\n
Answer 26. \na. It is provided by the force of friction between the tires of the car and the road. \nb. Banking of roads. \n <\/p>\n
