1 : 1.5 : 3, where 1 part of cement is to be mixed with 1.5 parts of sand and 3 parts of coarse aggregates.
Water requirement for the mix would be less than 25 liters per bag of cement.
As 5.5 m³ of concrete mix has 3 m³ of coarse aggregate,

Correct Option: B

Correct Option: D

For minimum no. of sprinklers, the spacing between them should be maximum.
Let us assume that shape of area coverage of the sprinkler is square. As area coverage of one sprinkler is 20 m²,
so the side of the square = √20 = 4.47
and satisfies 1.8 < 4.47 < 4.6

Proxemics : The branch of knowledge that deals with the amount of space that people feel it necessary to set between themselves and others. The 4 types of Proxemics are : Intimate, Personal, Social and Public. The concept was given by Edward T Hall.
Serial Vision : A prominent concept is that of ‘serial vision’, elaborated by Gordon Cullen. Serial Vision is the sequential and unfolding nature of urban experience (foreground/middle ground/background), with its corners, divisions/ modules, protrusions, and recesses/setbacks etc creating aspects of interest and surprise.
Urban Imageability : Kevin Lynch concerned himself with how we locate ourselves within the city, how we find our way around. He suggested that to know where we are within the city, we have to build up a workable image of each part. So, studying the legibility and imageability are essential required issues in the urban environment. K. Lynch defined the Legibility of the cityscape as the ease with which its parts can be recognized and organized into a coherent pattern. Kevin defined imageability as the quality of a physical object which gives an observer a strong vivid image. He put the elements as follows : Paths, Edges, Districts, Landmarks and Nodes.
Defensible Space : As defined by Oscar Newman, a defensible space is a “residential environment whose physical characteristics-building layout and site plan-function to allow inhabitants themselves to become key agents in ensuring their security.

An autotroph ("self-feeding", from the Greek autos "self" and trophe "nourishing") or "producer". Example- plants.
A heterotroph is an organism that cannot fix carbon and uses organic carbon for growth. This contrasts with autotrophs, such as plants and algae, which can use energy from sunlight (photoautotrophs) or inorganic compounds (lithoautotrophs).
Chemotrophs are organisms that obtain energy by the oxidation of electron donors in their environments. These molecules can be organic (chemoorganotrophs) orinorganic (chemolithotrophs). The chemotroph designation is in contrast to phototrophs, which utilize solar energy. Chemotrophs can be either autotrophic orheterotrophic.
Saprotroph, a term used for organisms which obtain nutrients from dead organic matt
