- Take a dynamometer of 1N
-  Suspend an object of 100g to the dynamometer
- Plunge the object suspended in the test-tube

The tide is the variation of the sea-level height, caused by the effect of the gravitational forces due to the revolution of the Earth around the center of gravity of the Earth-Moon system.

F = Force of gravity
G = Newton's constant
M1 = Mass 1
M2 = Mass 2
r = Distance

Gravitation is the attraction between two things which have a mass.
It's Newton who discovered gravitation with an apple that fall from the tree and never in any other direction.

Archimedes' thrust is the particular force exerted by a body immersed in whole or in part in a fluid (liquid or gaseous) subjected to a gravitational field.
This force comes from the increase of the fluid with the depth.
The pressure being stronger on the lower part of an immersed object than on its upper part, the thrust is vertical

She studies collisions of galaxies and their transformations during these collisions. It also seeks to know how stars that lie outside galaxies are born.

She was then hired following her request after meeting with NASA astronomers.

She thus began working with galaxies in close interactions and analyzed the effects of interactions on them.

# data[].attributes.body
Subsequently, she became more and more focused on how galaxies meet and transform  each other during interaction. She then held a postdoctoral position and worked as an adjunct  at Chalmers University.

And I like her because she sought to understand things that were not taught before what advanced our understanding of the universe.

Duilia de Mello was born in Sao Paulo and has always been curious and always wanted to know more about the universe. She became an astronomer to know all there was to know! Later on, she turned towards extragalactic astronomy to study extremely distant objects.
