I don't know how good you are at sketching ... I'm terrible.
But you can put the point across in a dramatic way if you
can sketch a bowling ball and a basketball ... you'll need
to clearly identify them with the markings you sketch on
each ball.
They're the same shape and nearly the same size, but
there's a huge difference in their densities.
im not gonna write a research paper but this is the really easy way write global warming talk about animals the polar ice caps and water levels then for what causes it burning fossil fuels and energy plants. then finish off with its awful and we should use solar or geothermic or wind or when the time comes fusion not fission fusion makes helium from hydrogen then burylliam from helium then oxygen and silicon so on so forth instead of fissions uranium,plutonium and thorium and with radioactive waste
#A
Mass=4.4kg
acceleration=-1.74m/s^2
Use newtons second law
#B
initial velocity=u
Final velocity=v=0
Acceleration=a=-1.74m/s^2
Time=t=1.27s
Answer: Please see below
Explanation:
Are pure substances that cannot be broken down into a simpler form---- Element
are units of two or more atoms---- Molecule
are the smallest possible particles of an element---- an Atom
are pure substances made of two or more atoms of different elements---- Compound
An atom is the smallest unit of matter that consists of protons, neutrons and electrons. Eg the element, helium, contains atoms with two protons in the nucleus.
Eg of element, we have carbon, hydrogen, helium
Eg of a compound--- Ammonia
Eg of a molecule-----H2O (water),C6H12O6 (glucose)
