Answer:

Forces come in pairs, so the force of gravity (9.8 N) with the mans weight (794N) on the earth is counteracted with the normal force ( the force of the earth back on the man) which is the same

a stone is projected vertically up from the top of a tower 73.5m with velocity 24.5 m/s . find the time taken by the stone to re
hoa [83]

The stone's altitude at time t is given by

y=73.5\,\mathrm m+\left(24.5\dfrac{\rm m}{\rm s}\right)t-\dfrac g2t^2

where g=9.80\dfrac{\rm m}{\mathrm s^2} is the acceleration due to gravity. The stone reaches the ground when y=0:

0=73.5\,\mathrm m+\left(24.5\dfrac{\rm m}{\rm s}\right)t-\dfrac g2t^2\implies t=7.11\,\rm s

PLEAS HELP.

<span>A: put an atom on a poster in the exhibit
     Good luck.  The poster itself is made of trillions of trillions of trillions
     of atoms.  You could not see the extra one any easier than you could
     see the ones that are already there, and even if you could, it would be
     lost in the crowd.
 
B: use a life size drawing of an atom
     Good luck.  Nobody has ever seen an atom.  Atoms are too small
     to see.  That's a big part of the reason that nobody knew they exist
     until less than 200 years ago.

D: set up a microscope so that visitors can view atoms
     Good luck.  Atoms are way too small to see with a microscope.

</span><span><span>C: Display a large three dimensional model of an atom.
    </span> </span>Finally !  A suggestion that makes sense.
     If something is too big or too small to see, show a model of it
         that's just the right size to see.
