Amuseum is creating an exhibit about atoms. which type of exhibit would best explain what atoms are? a. put an atom on a poster in the exhibit. b. use a life-size drawing of an atom. c. display a large, three-dimensional model of an atom. d. set up a microscope so that visitors can view atoms.

 
A).  No.  The entire poster is already covered with atoms,
but they're too small to see.

B).  No.  What's "life-size" of an atom ?  It's too small to see,
and that's the whole problem.

D).  No.  Atoms are too small to see even with a microscope.

C).  Yes !  A model of an atom, big enough to see, would help
get some of the important ideas across.

Explanation:

given,

mass of the satellite = 600 Kg

mass of earth = 5.98 x 10²⁴ Kg

height of the satellite

     r = 2 R_e

R_e is radius of earth = 6.38 x 10⁶ m

Assuming orbital velocity of the satellite

        v = 5.59 x 10³ m/s

    T = 14342.3 s
