It is given that a rhombus of perimeter 20 cm and one base angle is the supplement of 130 degree
From the given information we get 1 side of rhombus = 20/4 = 5cm
One angle = 130° therefore the adjacent angle = 180 - 130 = 50°
Drawing of rhombus
Step1: draw a line segment AB of 5 cm
Step 2: Draw line AX from A making an angle of 130° with AB and draw a line BY from B making an angleof 50° with AB
Step 3: Mark a point on AX as D such that AD = 5cm
Step 4: Mark a point on BY as C such that BC = 5cm
ABCD is arhombus of perimeter 20 cm and one base angle is the supplement of 130 degree

Given that, surface area of cube = 600 cm^2
Let the length of each side of cube be l.
Surface area of cube = 6 (Side)2
600 cm2 = 6 l2
l 2= 100 cm2
l = 10 cm
Thus, the side of the cube is 10 cm.

Causes of water pollution.
- Untreated sewage and effluents from cities are discharged into this river.
- River is used by people for bathing and washing clothes, also for bathing their cattle.
- Cremation of dead bodies on the banks of the Ganges is an age old practice, and this practice pollutes the river water.
- Rivers are preferred for immersing idols, flower and many other leftovers of rituals and worships.
- Many industrial towns are situated on the banks of this river, e.g. Kanpur.
- There are about 5000 industrial units in Kanpur; which include fertilizer, tanneries and paint industries. These factories release harmful chemicals into this river.
- Rampant use of weedicides, pesticides and chemical fertilizers pollute river water and groundwater.

Causes of ozone depletion:
- Methyl bromide
- Nitrogen oxides released from freezers, air conditioners, aerosol products and industrial solvents
- Compounds such as CFCs break down into chlorine atoms in the atmosphere. These chlorine atoms break down O3 into oxygen (O2) and nascent oxygen (O).

The term “prokaryote” is derived from the Greek word “pro“, (meaning: before) and “karyon” (meaning: kernel). It translates to “before nuclei.“
Prokaryotes are one of the most ancient groups of living organisms on earth, with fossil records dating back to almost 3.5 billion years ago.
These prokaryotes thrived in the earth’s ancient environment, some using up chemical energy and others using the sun’s energy. These extremophiles thrived for millions of years, evolving and adapting. Scientists speculate that these organisms gave rise to the eukaryotes.
The term “Eukaryotes” is derived from the Greek word “eu“, (meaning: good) and “karyon” (meaning: kernel), therefore, translating to “good or true nuclei.” Eukaryotes are more complex and much larger than the prokaryotes. They include almost all the major kingdoms except kingdom monera.
Structurally, eukaryotes possess a cell wall, which supports and protects the plasma membrane. The cell is surrounded by the plasma membrane and it controls the entry and exit of certain substances.

given,
the area of square is=5184m²
s×s=5184
s²=5184
s=√5184
s=72
according to problem,
l=2x
b=x
we know that,
perimeter of square=perimeter of rectangle
4s=2(l+b)
4×72=2(2x+x)
288=6x
x=288/6
x=48
from problem,
l=2x
=2×48
=96
b=x
=48
therefore length is 96
breadth is 48
area of rectangle = l × b
= 96 × 48
=4608 m²

In physics a force field is a vector field that describes a non-contact force acting on a particle at various positions in space. Specifically, a force field is a vector field {\displaystyle {\vec {F}}}{\vec {F}}, where {\displaystyle {\vec {F}}({\vec {x}})}{\vec {F}}({\vec {x}}) is the force that a particle would feel if it were at the point {\displaystyle {\vec {x}}}{\vec {x}}. In speculative fiction, a force field, sometimes known as an energy shield, force shield, force bubble, defence shield or deflector shield, is a barrier made of energy, plasma, or particles. It protects a person, area, or object from attacks or intrusions. This fictional technology is created as a field of energy without mass that acts as a wall, so that objects affected by the particular force relating to the field are unable to pass through the field and reach the other side. This concept has become a staple of many science-fiction works, so much that authors frequently do not even bother to explain or justify them to their readers, treating them almost as established fact and attributing whatever capabilities the plot requires.

As the formula states CP=(100/(100+Gain%))×SP
=(100/(100+12))×1596
=(100/112)×1596
=1425
∴ The cost price is ₹1425
