Solutions

S1.Ans. (b)
Sol. Fundamental physical quantities that do not depend upon other physical quantities. There are seven fundamental quantities- length, mass, temperature, time, electric current, luminous intensity and amount of substance.

S2.Ans. (d)
Sol. Units of physical quantities can be expressed in terms of fundamental units and such units are called derived units. Unit of area can be an example for derived unit.

S3.Ans. (b)
Sol. A physical quantity which has only magnitude is called scalar quantity. eg: speed and distance while physical quantities having both magnitude and direction are called vector quantities eg: velocity and displacement.

S4.Ans. (d)
Sol. The Golgi complex and rough ER work closely. When a protein is made in the ER, then transition vesicles are synthesized. These vesicles float through the cytoplasm to the Golgi apparatus and are absorbed. After the Golgi does its work on the molecules inside the sac or the vesicle a secretory vesicle is created and released into the cytoplasm. So the main function of the Golgi bodies is secretion. Respiration occurs in both plants and animals, cell division occurs during the phase of cytokinesis i.e. mitosis and meiosis, and gastric juices are those which help in digestion.

S5. Ans. (b)
Sol. Lysosomes are found in cytoplasm of the cell. It acts as the waste disposal system by digesting unwanted or harmful substances in the cytoplasm. Due to this act, they are known as ‘suicide bags’.

S6.Ans. (c)
Sol. Distillation is used to separate mixtures of liquids by exploiting differences in the boiling points of the different components.

S7.Ans. (a)
Sol. Washing machine works on the principle of centrifugation. Centrifugation is a process that involves the use of the centrifugal force for the separation of mixtures with a centrifuge, used in industry and in laboratory settings. More-dense components of the mixture migrate away from the axis of the centrifuge, while less-dense components of the mixture migrate towards the axis.

S8.Ans. (b)
Sol. Kelvin is the SI unit of thermodynamic temperature, and one of the seven SI base units. The Kelvin scale is an absolute thermodynamic temperature scale, meaning it uses absolute zero as its null (zero) point.

S9.Ans. (c)
Sol. Railway tracks are banked at the curves so that the necessary centripetal force may be obtained from the horizontal component of the reaction on the train. The outer track of the bend is slightly higher than the inner, this is known as banking of the rails or tracks, the following three kinds of force act on it:
the weight of the train acting vertically downwards,
the normal reaction provided by the track, acting upwards, to support the weight of the train, and
the frictional force acting between the contact area of wheels and the track surface helps the train move forward.

S10.Ans. (c)
Sol. Sclerenchyma tissues are found in hard parts of plant body, in cortex, pith, hypodermis, in the pulp of fruits. Young cells are living and they have protoplasm. But matured cells becomes dead due to deposition of secondary walls. They give mechanical support, strength and rigidity to the plant body.
