Solution
Ans.1.(c)
Exp. When pressure is increased, the melting point of ice decreases.
Ans.2.(a)
Exp. Sprayer functions are based on Bernoulli’s principle.
Ans.3.(c)
Exp. The fabrication of the transistor is the process of creating the transistor that is used in electrical and electronics circuit. Transistors are made from very pure silicon or germanium, but certain other semiconductor materials can also be used.
Ans.4.(a)
Exp. An electric current is a flow of electric charge which is often carried by moving electrons.
Ans.5.(a)
Exp. Electric fuse is a protective device which protects electrical equipment in the circuit by breaking the circuit when there is a short circuit.It has low melting point.
Ans.6.(b)
Exp. A transformer is used to bring voltage up or down in an AC electrical circuit.
Ans.7.(b)
Exp.Ozone layer thickness is expressed in terms of Dobson units, which measure, what its physical thickness would be if compressed in the earth’s atmosphere. 1 Dobson unit is defined to be 0.01 mm thickness STP (Standard Temperature and Pressure).
Ans.8.(c)
Exp. Lactometer is used for the measurement of the density of milk. Butyrometer is used to measure fat content in milk or milk products.
Ans.9.(d)
Exp. It is very difficult to walk on the ice than on the road because ice has a lesser friction than the road. The roughness of road’s surface gives you much frictional force which enables you to move forward on road.
Ans.10.(b)
Exp. Statics is a branch of mechanics associated with the situation or rest.
