Which of the following statements is incorrect in relation to the Data Link Layer Switching? we can join LANs together to make a larger LAN by using devices called repeaters on a single LAN a defective node that keeps outputting a continuos stream of garbage can clog up the entire LAN-by deciding what to forward and what not to forward bridges prevent that node from bringing down the entire system the algorithm used by the bridges is - backward learning repeaters, hubs, bridges, switches, routers, and gateways are in common use, but they all differ in subtle and not-so-subtle ways Previous question Next question

Which one of the following statements is incorrect in relation to ionization enthalpy?(a) Ionization enthalpy increases for each successive electron.(b) The greatest increases in ionization enthalpy is experienced on removal of electron from core noble gas configuration.(c) End of valence electrons is marked by a big jump in ionization enthalpy.(d) Removal of electron from orbitals bearing lower n value is easier than from orbital having higher n value. Which one of the following statements is incorrect in relation toionization enthalpy? (a) Ionization enthalpy increases for each successive electron. (b) The greatest increases in ionization enthalpy is experienced onremoval of electron from core noble gas configuration. (c) End of valence electrons is marked by a big jump in ionizationenthalpy. (d) Removal of electron from orbitals bearing lower n value is easierthan from orbital having higher n value. The option (d) represents incorrect statement. It states that "Removal of electron from orbitals bearing lower n value is easier than from orbital having higher n value". The correct statement is "Removal of electron from orbitals bearing lower n value is difficult than from orbital having higher n value". The attraction between the nucleus and the electron present in orbital having lower n value is higher than the attraction between the nucleus and the electron present in orbital having higher n value.

Relational Design Exercises Relational Design Exercises Functional Dependencies 1. Consider a relation R(A,B,C) and suppose R contains the following four tuples: A B C 1 2 2 1 3 2 1 4 2 2 5 2 For each of the following functional dependencies, state whether or not the dependency is satisfied by this relation instance. (a) A → B (b) A → C (c) B → A (d) B → C (e) C → A (f) C → B (g) AB → C (h) AC → B (i) BC → A 2. Which of the following rules for functional dependencies are correct (i.e., the rule holds over all databases) and which are incorrect (i.e., the rule does not hold over some database)? For incorrect rules, give the simplest example relation instance you can come up with where the rule does not hold. (a) If A → B and BC → D, then AC → D (b) If AB → C then A → C (c) If A → B1,..,Bn and C1,..,Cm → D and Which of these sets are equivalent? (Two sets of functional dependencies (FDs) F and F' are equivalent if all FDs in F' follow from the ones in F, and all FDs in F follow from the ones in F'.) Multivalued Dependencies 7.Consider a relation R(A,B,C) and suppose R contains the following five tuples: A B C 1 2 3 1 3 2 1 2 2 3 2 1 3 2 3 For each of the following multivalued dependencies, state whether or not the dependency is satisfied by this relation instance. (a) A → > B (b) A → > C (c) B → > A (d) B → > C (e) C → > A (f) C → > B 8.Consider a relation R(A,B,C,D) that satisfies A → > B and B → > C. Suppose R contains the tuples (1,2,3,4) and (1,5,6,7). What other tuples...

\( \newcommand\) • • • • • • • • • • • • • • • • • PREVIEW ACTIVITY \(\PageIndex\) • Find two different examples of two ordered pairs \((x, y)\) and \((y, z)\) such that \((x, y) \in R\), \((y, z) \in R\), but \((x, z) \notin R\), or explain why no such example exists. Based on this, is the following conditional statement true or false? For all \(x, y, z \in A\), if \((x, y) \in R\) and \((y, z) \in R\), then \((x, z) \in R\). • Is the following conditional statement true or false? Explain. For all \(x, y \in A\), if \((x, y) \in R\) then \((y, x) \in R\). PREVIEW ACTIVITY \(\PageIndex.\) Introduction to Relations In relation in the sense that each element of the first set, the domain, is “related” to exactly one element of the second set, the codomain. This idea of relating the elements of one set to those of another set using ordered pairs is not restricted to functions. For example, we may say that one integer, \(a\), is related to another integer, \(b\), provided that \(a\) is congruent to \(b\) modulo 3. Notice that this relation of congruence modulo 3 provides a way of relating one integer to another integer. However, in this case, an integer \(a\) is related to more than one other integer. For example, since \(5 \equiv 5\) (mod 3), \(5 \equiv 2\) (mod 3), and \(5 \equiv -1\) (mod 3), we can say that 5 is related to 3, 5 is related to 2, and 5 is related to -1. Notice that, as with functions, each relation of the form \(a \equiv b\) (mod 3) involves two integersa and...

The correct option is D Linear momentum = Moment of inertia × Angular velocity The explanation for the correct options: In the case of options A, B, and D, • The Torque in rotational motion is equivalent to force in linear motion. It is the prime parameter that keeps an object under rotatory motion. The torque applied to an object begins to rotate it with an acceleration inversely proportional to its moment of inertia. • Mathematically, it can be expressed as, T = I α, Where, I is a moment of inertia and, α is angular acceleration. Angular momentum is defined as the property of any rotating object given by moment of inertia times angular velocity. • Mathematically, it can be expressed as, L → = I × ω →, Where, L → is the Angular momentum, I is the moment of inertia, and ω → is the angular velocity. • The Torque in rotational motion is equivalent to force in linear motion. It is the prime parameter that keeps an object under rotatory motion. The torque applied to an object begins to rotate it with an acceleration inversely proportional to its moment of inertia. Mathematically, it can be expressed as, T = I α, Where, I is a moment of inertia and, α is angular acceleration. 4. Magnetic moment, also known as magnetic dipole moment, is the measure of the object’s tendency to align with a magnetic field. 5. The magnetic moment is a vector relating torque Ï„ of an object to the magnetic field. This is mathematically represented as: Ï„ = m × B, where, m is the m...
