Solutions:
S1.Ans.(c)
Sol. An image stays on the retina for about 1/16 of a second. This feature is called persistence of vision.
S2.Ans.(d)
Sol. Newton’s second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
S3.Ans.(b)
Sol. The coil wire is heating element in electric room heater or electric cooking heater to converts electricity into heat through the process of resistive or Joule heating. Electric current passing through the element encounters resistance, resulting in heating of the element.
S4.Ans.(b)
Sol. Energy in the form of heat is wasted when a machine is operated. This heat is generated due to Friction between two parts.
S5.Ans.(c)
Sol. The law of reflection states that the incident ray, the reflected ray, and the normal at the point of incidence all lie in the same plane.
S6.Ans.(b)
Sol. A concave mirror is capable of producing a real image.
S7.Ans.(c) 
Sol. The distance-time graph for the motion of an object moving with a constant speed is a Straight Line.
S8.Ans.(a)
Sol. If the force applied on the object is in the direction of its motion, the speed of the object increases.
S9.Ans.(a)
Sol. If an object moves in a circular path with uniform speed, its motion is called uniform circular motion.
S10.Ans.(c)
Sol. The reflection formed by the plane mirror is Lateral inversion.
