False, there are always pros and cons to research
Here since both children and merry go round is our system and there is no torque acting on this system
So we will use angular momentum conservation in this
now here we have
Now when children come to the position of half radius
then we will have
now from above equation we have
Gamma-rays, the explanation and information is found in the image below.
Hi
only compound must two different atom.
Element have made by only single atom.
_________________________________
Compound:
A compound is formed when two or more elements chemically combine together. The elements react chemically and form chemical bonds between the atoms of the elements.
A mixture is a combination of two or more substances which are not chemically the same. ____________________________________
Homogeneous mixtures:
Homogeneous mixtures have uniform composition and appearance throughout .A homogeneous mixture is also called a true solution.
Example: sugar solution, ocean water, soft drinks, etc.
____________________________________
Heterogeneous mixtures:
Heterogeneous mixtures consist of different substances.
Examples: mixture of iron and sulphur, mixture of sand and table salt, etc.
so only elements are single atom.
all these are combination of atoms.
thanks for asking
