Answer:

<u>distance</u><u> </u><u>between</u><u> </u><u>should</u><u> </u><u>be</u><u> </u><u>1</u><u>.</u><u>2</u><u>5</u><u> </u><u>×</u><u> </u><u>1</u><u>0</u><u>^</u><u>6</u><u> </u><u>m</u>

Explanation:

Force is proportional to separation distance.

250 \: newtons = 2.5 \times  {10}^{6}  \: metres \\ ( \frac{1}{2}  \times 250) \: newtons = d \\  \\ d =  \frac{125 \times 2.5 \times  {10}^{6} }{250}  \\ d = 1.25 \times  {10}^{6}  \: metres

What are stars made of?<br> How do they expand?<br> How do they explode?
lutik1710 [3]
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements,  star is in a delicate and fragile balance between gravity, which would collapse the star to a point, and its internal pressure caused by the energy of the nuclear fusion reaction in the core. When a star's fuel has been spent, it explodes into a giant fireball known as a supernova.. I really hope this helps!!!!
