Solutions

S1.Ans. (b)
Sol. Minerals are naturally occurring compounds metals these are inorganic solid. eg.Hematite is mineral of Fe and Al2O3 (alumina) is a mineral of Al. These mineral from which metals are extracted are known is ores.

S2.Ans. (d)
Sol. A couple has the only effect of producing or preventing the turning effect of the body.
Application of Couple
Steering wheel applied by the car driver, Opening and closing of a water tap, Winding the spring of an alarm clock, Unlocking the locker by using a key etc.

S3.Ans. (b)
Sol. The value of G is a constant like other constants and is independent of factors such as medium, temperature pressure etc. The value of gravitational constant of the earth is independent on the mass and radius of the earth.

S4.Ans. (a)
Sol. Milk is a mixture composed of water, along with fat and sugar. Chief among these protein is called caseins which make up about 80% of the proteins in milk.

S5.Ans. (b)
Sol. An object when thrown upwards reaches a certain height and then falls downward due to pull by gravitational force of the earth. In absence of gravitational force of the earth object wouldn’t fall back.

S6.Ans. (a)
Sol. A detergent is a cleansing agent. Both detergents and soap can clean, but they are different chemically. A soap is the metal salt of long-chain fatty acid. The metal may be an alkali metal such as sodium (Na) or potassium (K).

S7.Ans. (a)
Sol. A gas, when kept at a constant temperature, would obey the gas laws exactly. The gas laws are Charle’s law, Boyle’s law and Gay-Lussac’s law.

S8.Ans. (b)
Sol. When the osmotic pressure outside the red blood cells is the same as the pressure inside the cells, the solution is isotonic with respect to the cytoplasm. This is the usual condition of red blood cells in plasma. Hence the cells do not shrink.

S9.Ans. (d)
Sol. Xylem tissue is the specialized conducting system of the plants. It is the main conducting system for water and some mineral nutrients from roots to the shoot.

S10.Ans. (a)
Sol. The value of g decreases with height and depth from the earth’s surface. The intensity of the Gravitational field of the Earth is maximum at the poles and it is minimum at the equator. The value of g decreases due to the rotation of the Earth. Poles being a little closer to the centre of gravity, intensity of gravity is the maximum.
