ans:In physics, the Coriolis force is an inertial or fictitious force that acts on objects that are in motion within a frame of reference that rotates with respect to an inertial frame. In a reference frame with clockwise rotation, the force acts to the left of the motion of the object.

d) both ‘a’ and ‘c’ 

b) Ball- bearings

A = 100 cm² = 100 x 10^-ym² = 10^-2m²

θ = 30°

B = 10^-1T

∴ Flux,   ϕ = \(\vec{B}.\vec{A}\) 

= BA cosθ

= 10^-1 x 10^-2 x cos30°

= 10^-3x \(\frac{\sqrt{3}}{2}\)

 =  \(\frac{\sqrt{3}}{2000}\) Wb.

Induced emf, |e| = \(\frac{-dϕ}{dt}\) = \(\Big[\frac{ϕ_f-ϕ_i}{Δt}\Big]\)

= -\(\Big[\frac{0-1.732}{\frac{2000}{10^{-3}}}\Big]\)

=  \(\frac{1.732}{2000}\times\frac{1}{10^{-3}}\) 

= \(\frac{1.732}{2}\) 

= 0.866 V.

Torsion force is found machine axles, twist drills and driving shafts. 

a) Decrease mycobacterium drug-resistance

b) Pyrazinamide

a) Pyrazinamide

Answer: Not less than 5 days

Answer: Destroying of bacterial cells

Horizontal portioning is where the rows in a relation are separated by some criteria and placed into a new relation or file with the same layout as the original relation (in this case only the records in each file differ). Vertical portioning is where the columns in a relation are separated by some criteria and placed into a new relation or file with a different layout as the original relation.

The correct Boolean expression is (a) & (d)

(a) and (d) are logical statements because these statements have a truth value which may be true or false.

The NOT gate is named as Inverter.

Information helps us to take decisions

1. Data Capture 

2. Input 

3. Storage 

4. Process 

5. Output 

6. Distribution

The hierarchical model is a top-down structure where each parent may have many children but each child can have only one parent. This model supports one-to-one and one-to-many relationships. The network model can be much more flexible than the hierarchical model since each parent can have multiple children but each child can also have multiple parents. This model supports one-to-one, one-to-many, and many-to-many relationships.

Manipulation of data to get information is known as Data processing

A set of wire connected between the control unit and other units like memory, Input/Output device.

(b) Storage. It is one of the data processing stage the others are various operations in the stage Process

Data processing

False Information may act as data

In Positional number system, each position has a weightage. True

Data is a collection of unorganized fact.

Denormalization is the process of taking normalized relations and changing them so that they are not longer normalized. This process may lead to anomalies and create data redundancy as negative consequences. However, the revised relations should improve database performance.

Data can be organized into useful  Information

The five logical operators available in SQL are

1. Single inheritance:
A derived class with only one base class is called single inheritance. For example, If A is base class then class B derive from base class A.

2. Multilevel inheritance:
A class can be derived from another derived class which is known as multilevel inheritance. For example, The derived class C inherit B class whereas B is derived from class A.

3. Hierarchical inheritance:
When the properties of one class are inherited by more than one class, it is called hierarchical inheritance. For example, classes B, C, and D are derived from base class A.

4. Hybrid inheritance:
It is the combination of hierarchical and multilevel inheritance. For example, The derived class D derive from the classes B and C whereas both the classes B and C are derived from base class A.

The difference between manual and electronic file systems.

A unique primary index is unique and is used to find and store a row. A nonunique primary index is not unique and is used to find a row but also where to store a row (based on its unique primary index). A unique secondary index is unique for each row and used to find table rows. A nonunique secondary index is not unique and used to find table rows.

All the activities of a computer is controlled by the control unit. That means the function of key board, mouse, monitor, memory etc. are controlled by the control unit.

Distribution of information is the final stage in data processing

a) Data Capture 

b) Input 

c) Storage 

d) Process 

e) Output 

f) Distribution

A data type should be selected so that all possible values are represented using minimal storage space. The data type should help to ensure data integrity and support all possible data manipulations (i.e., cannot place a letter in a field such as salary where a number is required).

Domain constraints include entity integrity and referential integrity. The domain is a set of values that may be assigned to an attribute. The entity integrity rule states that no part of a primary key cannot be null. Referential integrity states that each foreign key value must match a primary key value or be null.

A separate relation is created for each supertype and subtype. The attributes common for all of the subtypes are assigned to the supertype. Each subtype has the primary key from the supertype assigned to it. A subtype discriminator is added to the supertype.

lSCII (lndian Standard Code for Information Interchange)

ASCII means American Standard Code for Information Interchange. It is a 7 bit code. Each and every character on the keyboard is represented in memory by using ASCII Code.

eg: A’s ASCII Code is 65 (1000001), a’s ASCII Code is 97 (1100001)

First you must verify that a relation is in both first normal form and second normal form. If the relation is not, you must convert into second normal form. After a relation is in second normal form, you must remove all transitive dependencies.

Data is a collection of unorganized fact.

Relations in a database have a unique name and no multivalued attributes exist. Each row is unique and each attribute within a relation has a unique name. The sequence of both columns and rows is irrelevant.
