<h2><u>FORMAT</u><u>ION</u></h2>
Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material
Hope It Helps!
Because less energy is being wasted. non-renewable resources will last longer.
the cost is kept lower. hope it helps :)
Evolution should be the answer
Only the masses of the objects and the distance between them. Nothing else affects the gravitational forces. Not even a concrete, steel, and Kryptonite wall between them.
M*g*sin20-f=m*a
<span>and the rotational frame </span>
<span>f*r=I*a/r </span>
<span>where f is the force of friction, a is the translational acceleration and I is the moment of inertia of the sphere </span>
<span>combine and solve for f </span>
<span>a=g*sin20-f/m </span>
<span>and </span>
<span>f*r^2/I=g*sin20-f/m </span>
<span>or </span>
<span>f=g*sin20/(r^2/I+1/m) </span>
<span>I=2*m*r^2/5 </span>
<span>therefore </span>
<span>f=2*m*g*sin20/7</span>
