1 viscous
2 non-volatile
3 both (1and 2 )
4 transparent
Laws of Motion

1 Solids
2 Liquids
3 Gases
4 Both 2 and 3
Laws of Motion

270110 A block ' \(B\) ' rests on ' \(A\) '. A rests on a horizontal surface ' \(C\) ' which is frictionless. There is friction between \(A\) and \(B\). If ' \(B\) ' is pulled to the right

1 B moves forward and A to the left
2 ' \(B\) ' only moves to the left
3 ' \(B\) ' does not move
4 ' \(A\) ' and ' \(B\) ' move together to the right
Laws of Motion

270111 Sand is dusted to the railway tracks during rainy season to

1 make it always wet
2 increase friction
3 to reduce consumption of fuel
4 make it always dry
Laws of Motion

270112 With increase of temperature, the frictional force acting between two surfaces

1 increases
2 decreases
3 remains same
4 may increase or decrease
