When the object is placed in a graduated cylinder containing 175 ml of water, the water in the cylinder rises to a level of 187.5 ml , this implies that volume of content in the container has increased , the increased volume is volume of the object placed
So, Volume of object
= Increased Volume - Initial volume
= > 187.5 -175
= > 12.5 ml
Since 1 ml = 1 cm³ we can write
[tex]\quad[/tex]12.5 ml = 12.5 cm³
Now,
[tex]\green{ \underline { \boxed{ \sf{Density= \frac{Mass}{Volume}}}}}[/tex]
Putting Values -
[tex]\begin{gathered}\\\implies\quad \sf Density = \frac{32.5}{12.5} \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf Density = \frac{325}{125} \\\end{gathered} [/tex]
[tex]\begin{gathered}\\\implies\quad \sf Density = 2.6 g/cm^3 \\\end{gathered} [/tex]
>> The density of the material is 2.6 g/cm³

A.On human skin
B.On sea ice in Antarctica
C.In the field of a wheat farm
D.In a river flowing through a valley
The corrrect answer is B , On sea ice in Antarctica , it is most likely to find Archaea domain .
What is an Archaea Domain ?
These domain include microorganisms that can survive in the most extreme environments , these are classified in Eukaryota, Eubacteria, and Archaebacteria .
On the basis of research it has been found that many of the Archaea domains have been found on the surface water in cold marine environments .
Therefore it is most likely that Archaea domain to be found on sea ice in Antarctica. Hence correct answer is B .

You will observe the orbits and you have to determine how many planets are in the habitable zone and how many are orbiting successfully. Based on the mass of the star and the placements of the planets, planets may swerve into the star and vanish, collide with each other and vanish, float out of orbit, or all orbit successfully. You will record this information and each planet's orbit in your data table for each trial. If the mass of the sun is 1x, planets will fall into the habitable zone if I place a planet in orbits (Orbit=1,2,3,4,5,6,7,8), and all planets will orbit the sun successfully.
If the mass of the sun is 2x, planets will fall into the habitable zone if I place a planet in orbits (Orbit=1,2,3,4,5,6,7,8), and all planets will orbit the sun successfully.
If the mass of the sun is 3x, planets will fall into the habitable zone if I place a planet in orbits (Orbit=1,2,3,4,5,6,7,8), and all planets will orbit the sun successfully.

fill in the blanks: label the different parts of the rock cycle where igneous, sedimentary, and metamorphic rock are formed.
Answer:
☞rock cycle
=> The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions.
=> There are three main kinds of rocks: igneous rock, metamorphic rock, and sedimentary rock. ... It can erode into sediment or melt into magma. It is formed under extreme pressure and temperature deep inside mountain chains.

Write an equation for the reaction that takes place in a luminous flame assuming the laboratory gas is Butane
Answer:
Fire's basic combustion equation is: fuel + oxygen —> carbon dioxide + water, a line many of us had drummed into us by school teachers. However, combustion reactions do not proceed directly from oxygen to carbon dioxide.

Fire's basic combustion equation is: fuel + oxygen —> carbon dioxide + water, a line many of us had drummed into us by school teachers. However, combustion reactions do not proceed directly from oxygen to carbon dioxide.
The equation for luminous flame assuming the laboratory gas is butane is fuel + oxygen → [tex]CO_{2} + H_{2}O[/tex].
What is butane?Natural gas, the source of butane, would be a colorless, odorless, but also shapeless gas by nature. This kind of gas is extremely prevalent throughout the world and seems to be comparatively cheap to mine as well as produce.
What is a luminous flame?A burning flame that is clearly seen would be called a luminous flame.
When fuel is reacted with oxygen gas then it will form carbon dioxide and water. It can be written as:
fuel + oxygen → [tex]CO_{2} + H_{2}O[/tex].
