Answer: a all the outer planets are large
Explanation: because i have the smarts
Known values; mass per / volume and mass of each atom
average volume=<span> volume per atom. </span>
<span>density*mass per atom = volume per atom </span>
<span>1cm^3 / 7.87 gram * 9.27 *10^-26 kg /atom* 1000 gram / kg=
</span>=<span>1.178 * 10^-22 cm^3 per atom </span>
<span>Convert that to mass </span>
<span>1 cm^3 * (1 m / 100 cm)^3 </span>
average volume= <span>1.178 *10^-29 m^3 per atom </span>
<span>distance: </span>
<span>Volume of a cube is L^3 </span>
<span>so L = (1.178*10^-29)^(1/3) </span>
<span>Half way through the cube is distance 1/2 L. </span>
<span>Second cube is 1/2 L </span>
<span>So distance between the center of 2 cubes = L </span>
=2.28 *10^-10 m

Answer: The ball (option A)
Explanation: change in momentum is defined by the formulae m(v - u) where m = mass of object, v = final velocity and u = initial velocity.
For the ball, it hits the ground and bounces back with the same speed, that's final velocity equals initials (v = - u)
Change in momentum = m( -u- u) = m(-2u) = m(-2u) = -2mu
For the clay, it final velocity is zero since it sticks to the floor, hence (v =0)
m(v - u) = m(0 - u) = - mu.
-2mu (change in momentum from the ball) is greater than - mu ( change in momentum of clay)
