An object is said to be in uniformly accelerated motion if the velocity of the moving object
changes by equal amounts in equal intervals of time.
Two equations of motions are:
V= u + at
S = ut + ½ at2.
14. Mass of an object is a measure of its inertia and has a unit kg. Weight of an object is the force
acting on it due to gravity that W= mg. S.I unit of weight is N.
Mass of object, m = 10 kg, g = 10 m/s2.
Weight of object on earth = 10 x 10 = 100 N.
Weight of object on moon = 100/6 = 16.67 N.
15.

insects that feeds on weeds and destroy them.
17. Integrated farming practices means combining agriculture with livestock, poultry, fisheries,
beekeeping etc. It increases the income of people involved in agriculture as well as combat
the problem of hunger and sustained livelihood.
Improvement in poultry breeds involves cross breeding the indigenous varieties with exotic
breeds. The improved varieties are developed for the following desirable traits:
(i) to improve the quality and quantity of chicks.
(ii) to develop dwarf broiler parent for commercial chick production.
(iii)tolerance of high temperature
(iv) low maintenance requirements.
18. Production practices in agriculture involve three components namely nutrient management,
irrigation and cropping pattern. It controls the various aspects of crop production so as to
obtain the maximum and the best yield.
(a) Nutrient management involves the selecting, timing and amount of nutrient supply to
the crops.
(b) Irrigation is the process of supplying water to crop plants through human efforts by
means of canals, wells, tube wells etc.
(c) Cropping pattern involves obtaining maximum benefits from the same piece of land.
19. (a) (i) Sugar solution gives the Tyndall effect but starch solution does not.

(iii) Sugar solution is transparent but the starch solution is translucent.
(b) (i) Evaporation and crystallization.
(ii) Centrifugation.
(iii) Magnetic separation.
20. (a) When sugar is dissolved in water, its crystals breaks into tiny particles. The sugar
particles go into the spaces between the particles of water and mix with them to form sugar
solution. The sugar particles occupies the space between water particles.
From the dissolution of sugar in water, we infer that
(i) The matter consisting of sugar and water is made up of small particles.
(ii) The particles of matter have space between them.
The compound which can undergo sublimation themselves but contain impurities which
cannot sublime can be purified by the process of sublimation.
21. (i) Cardiac muscles are involuntary, striated and non-fatigue muscles which is located in the
walls of heart to perform rhythmic contraction and relaxation throughout life. The cells are
uninucleate, small and cylindrical with broad ends.
(ii) The tissue which is under the control of will and work as per the requirement of body is
striated or skeletal muscular tissue. They are voluntary in nature.
(iii) Ligaments are cord likes dense yellow fibrous connective tissue of considerable
strength and high elasticity. They binds a bone with another bone. Because of elasticity a
ligament allows bending and rotation of over joint.
22. (a) The average speed of an object is defined as the ratio of total distance covered by the
object and total time taken by it to cover that distance.
The average velocity of an object is defined as the ratio of net displacement of the object and
the total time for that displacement.
(b) From the given graph
Velocity of A = displacement/time = 80- 20 m/8-0s = 7.5 m/s
Velocity of B = 60-40m/8-0s = 2.5 m/s
The meeting point of A and B is at 50 m and at 4 s.
23. (a) (i) When a person jumps from a boat to the shore, the boat moves backwards due to
reaction force according to third law of motion.
(ii) When a person fires a gun, the bullet moves in forward direction and in turn the gun
recoils in backward direction. Due to recoil motion of gun person experience an jerk in
backward direction.
(b) Third law states that to every action there is an equal and opposite reaction. The action
and reaction are equal in force but opposite in direction.
(c) Mass of object, m = 20 kg. Initial velocity, u= 36 km/h = 10 m/s.
Final velocity, v= 54 km/h = 15m/s. time, t = 25 s.
Initial momentum = mu = 20x 10 200 kg m/s.
Final momentum = mv = 20x 15 = 300 kg m/s.
Magnitude of force = change in momentum/time = 300 – 200/25 = 4N.
24. (a) Irrigation is important to ensure that crops get water at the right stages during growth.
The important water sources are wells, canals, rivers and tanks.
Wells- they are shafts sunk into ground that reach water table and are used to draw water. It
may be tube wells or dug wells.
Canals- they form a extensive irrigation system, where in they get water from large rivers.
The main canal is divided into branch canals and further into distributaries to irrigate the
field.
Rivers- in area where canal flow in insufficient or irregular due to inadequate reservoir
release, the water is directly drawn from river for irrigation.
(b) Rain water harvesting is a method which does not allow main water to go waste. It is
collected and used for recharging ground water by sinking deep drain pipes. It can be
poured into wells or used for filling ponds in low level area. In water shed management,small check dams are built up in water shed area to increase percolation of water into
ground, reduce flow of main water and prevent soil erosion.
