Question Discussion & Solution

The correct answer is ​Heat is absorbed.

Key Points

•  When ice is converted into water heat is absorbed by the ice, so the molecules of ice increase their energy and convert into water. Hence option A is correct.
• Additional Information
• The conversion of ice into water is an example of melting. If you took out the ice cubes from the freezer and placed them in a warm room, the ice would absorb energy from the warmer air around them. This absorbed energy would facilitate them to overcome the force of attraction holding them together, enabling them to slip out of the fixed position that they held as ice. The process in which solids change to a liquid is called melting. The melting point is the temperature at which a solid changes to a liquid. 
• The static water is converted to ice It means when the water is converted into ice its potential energy decreases. 
• If we compare the kinetic and potential energy of the water vapor, water and ice then water vapor has the most kinetic as well as potential energy as compared to water and ice.
• This is because the particle of water vapor is free to move and they can move more vigorously. Please note that kinetic energy is associated with moving objects whereas potential energy is associated with a static object. 

The longest Highway in the state is NH 15 of length 878.3 km and Smallest is 71B of length 5 km.

• The highway starting from the junction of NH- 71 near Rewari in the state of Haryana of 69 km and connecting Dharuhera and passing through Rajasthan of 5 km and connecting Taoru -Sohna and terminating at its junction with NH 2 near Palwal.
• NH 79 A - Kishangarh- Nashirabad - 35 km
• NH 11 C - Old alignment of NH no. 8 passing through Jaipur. Length in Rajasthan 53 km
• NH 3 - Agra-Gwalior-Shivpuri-Indore-Dhule-Nasik-Thane-Mumbai. Length in Rajasthan 32 km

Saw is used for cutting wood.

Similarly, Scythe is used for cutting Grass.

A constructor is a member function of a class that initializes objects of a class. In C++, Constructor is automatically called when an object (instance of a class) creates. It is a special member function of the class.

Syntax

class_name(parameter1, parameter2, ...)

{

    // constructor Definition

}

Default Constructor

It is the constructor that doesn’t take any argument. It has no parameters.

Parameterized Constructors

It is possible to pass arguments to constructors. Typically, these arguments help initialize an object when it is created. 

Copy Constructor

A copy constructor is a member function that initializes an object using another object of the same class.

The correct answer is Select, where, group by, having.

Additional Information

Six Operations to Order: SELECT, FROM, WHERE, GROUP BY, HAVING, and ORDER BY. Because the database executes query components in a specific order,

SELECT select_list [ INTO new_table ]  [ FROM table_source ]

[ WHERE search_condition ]

[ GROUP BY group_by_expression ]

[ HAVING search_condition ]

[ ORDER BY order_expression [ ASC | DESC ] ]

Hence Option 4 is correct
