A mixture is a combination of two or more elements that can be separated using physical means such as filtration, evaporation,...etc
A mixture can be one of two types:
1- homogeneous mixture where you cannot identify the elements easily by the naked eye. Example is sugar and water mixture.
2- heterogeneous mixture where you can easily identify the elements through naled eye.
Example is mixture of rocks and sand.
Based on the above, you can easily infer that:
a heterogeneous mixture is a mixture in which the components retain their identity.
Answer:
Explanation:
Let the cross sectional area be a cm .
volume of hydrometer inside liquid = 12 x a = 12 a
weight of liquid displaced = 12a x .8 x g = 9.6 a g
For free floatation of liquid
weight of hydrometer = weight of displaced liquid
9.6 a g = 100 g
a = 10.41 cm²
cross sectional area = 10.41 cm².
Answer:
An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction. In collisions of macroscopic bodies, some kinetic energy is turned into vibrational energy of the atoms, causing a heating effect, and the bodies are deformed.
Explanation:
Answer:
The energy is

=>
Generally the corresponding energy stored in the circuit is
Answer: Electric force
Explanation:
The electric force is a force that is inversely proportional to the square of the distance. This can be proved by Coulomb's Law, which states:
<em />
<em>"The </em><em>electrostatic force</em><em> between </em><em>two point charges </em><em> and is proportional to the product of the charges and </em><em>inversely proportional to the square of the distance</em><em> </em><em>that separates them</em><em>, and has the direction of the line that joins them" </em>
<em />
Mathematically this law is written as:
Where is a proportionality constant.
