Which of the following sets cannot enter into the list of fundamental quantities in any system of units ?
Detailed Solution for Test: Units & Measurement - 3 - Question 1
We define length and time separately as it is not possible to define velocity without using these quantities. This means that one fundamental quantity depends on the other. So, these quantities cannot be listed as fundamental quantities in any system of units.
Detailed Solution for Test: Units & Measurement - 3 - Question 2
Parallactic second is the unit of distance because parallactic second is an abbreviation of parsec. Parsec = Parsec is the Unit for larger distances.It is the distance at which a star would make parallax of one Second of arc.
Detailed Solution for Test: Units & Measurement - 3 - Question 3
The newton second (also newton-second, symbol N s or N.s) is the derived SI unit of impulse. It is dimensionally equivalent to the momentum unit kilogram metre per second (kg.m/s). One newton second corresponds to a one-newton force applied for one second.
If a and b are two physical quantities having different dimensions then which of the following can denote a new physical quantity
Detailed Solution for Test: Units & Measurement - 3 - Question 8
Quantities with different dimensions cant be added or subtracted. Also the dimension of the product of the quantities in power is always one. But when two quantities are multiplied the dimension of the product is the product of the dimensions of the initial quantities.
Two physical quantities whose dimensions are not same, cannot be :
Detailed Solution for Test: Units & Measurement - 3 - Question 9
The two physical quantities which do not have the same dimensions can’t be added or subtracted in the same expression because doing so would lead to equating two quantities of different dimensions, which is non possible. Ex [F] [P].
Detailed Solution for Test: Units & Measurement - 3 - Question 10
Correct Answer :- d
Explanation : a) A topological sort of a directed acyclic graph (DAG) is any ordering m1, m2, …, mn of the nodes
of the graph, such that if mimj is an edge then mi appears before mj . Any topological sort of a
the dependency graph gives a valid evaluation order for the semantic rules.
b) The parse tree can be annotated with synthesized or inherited attributes. The parse tree can also be indicated with an arrow mark to indicate the manner in which the value gets propagated between the nodes of the parse tree. This graph is called as dependency graph as it indicates the dependency between nodes for deriving the values. This graph is an acyclic graph which doesn’t have a cycle. The presence of a cycle indicates that the graph is incorrect as the dependence of nodes for deriving values cannot be predicted. Edges in the dependence graph show the evaluation order for attribute values and thus the graph is a directed one.
When a wave traverses a medium, the displacement of a particle located at x at time t is given by y = a sin (bt - cx) where a, b and c are constants of the wave. The dimensions of b/c are the same as those of
Detailed Solution for Test: Units & Measurement - 3 - Question 24
Argument of sin is dimensionless and using principle of dimensional homogeneity, we get
Thus, ∣b∣=T−1 and ∣c∣=[L−1]
Thus, dimensions of b/c are [LT−1], which is the same as the velocity of wave.
