Answer:
Passive solar heating system
Explanation:
The goal of passive solar heating systems usually refers to the system in which the energy provided by the sun is used for heating and cooling of the living places in a house.
When sunlight falls on the house, the building elements capture the heat energy of the sun and it later releases back this heat when the sun is not there. The main objective of this system is to regulate the room temperature. It is comprised of two main elements, one is the glasses that face towards the south and a thermal mass that is used for heat absorption, storing and distribution of heat.
Answer:
Answer is (d) value of 10
Explanation:
Usually when we write "int x=10;", a memory space is allocated for an integer variable with name x, and content 10.
Answer:

Explanation:
Given
Options A to D
Required
Which deletes the first occurrence of 3
The options show that the question is to be answered using the knowledge of Python.
So, we analyze each of the options using Python syntax
(a) listB.clear(3)
In python, clear() is used to delete all elements of a list, and it does not take any argument i.e. nothing will be written in the bracket.
<em>Hence, (a) is incorrect</em>
(b) listB(3)
The above instruction has no meaning in Python
(c) listB delete(3)
The above instruction as written is an invalid syntax because of the space between listB and delete.
Also, it is an invalid syntax because lists in Python do not have the delete attribute

This removes the first occurrence of 3
