The answer is B 1,500 meters since 1 kilometer to meters is 1,000 and u add the 500
That if you see them in a dogram they are not like a solid state of matter and not like a glass they are close together but not in rows
Is this what you mean I’m not sure but that’s what I seee
Answer:
The kinetic energy of the heavier block after the push is equal to the kinetic energy of the lighter block
Explanation:
Kinetic energy of smaller object

where m= mass of smaller object and v= velocity of smaller object
Also, it is given that heavier object is four times the mass of lighter object and consider its velocity as V
kinetic energy of heavier block 
Now, For smaller block , 
[by Newtons laws of motion]
Also, 
Where S= displacement, F= force, u= initial velocity
So, ![K=(1/2)m[2(F/m)]S](https://tex.z-dn.net/?f=K%3D%281%2F2%29m%5B2%28F%2Fm%29%5DS)

For heavier block ,

or, 
So,

Therefore the kinetic energy of the heavier block after the push is equal to the kinetic energy of the lighter block
The number 4 represents four atoms of iodine per molecule. Thyroxine is a type of hormone produced by the thyroid gland and this hormone controls human's metabolism process. There are two hormones produced by the thyroid gland, the thyroxine and the triiodothyronine, which also control human's metabolism process. These hormones consisted of iodine atoms in each of the molecule, which human gets from eating salt.
