Answer:
You could move something across the Earth with a little push. It would make fuel really efficient on those pathways. You could make a floor that is impossible to walk on. Everybody would just fall without traction.
Explanation:
Answer:
68.2 Quadrillion meters
Explanation:
A lightyear is the distance that light travels in one year.
Speed of light is 
So light covers 300,000,000 meters in one second.
One year has 31536000 seconds so , light covers
so 7.2 light years is
so 7.2 light years is
6.82 x 10^(16) meters or
68.2 Quadrillion meters
The answer is false. The speed of the astronaut cancels out the force of gravity, causing a 'stationary freefall'. While under these effects, it is not required for an astronaut to 'strengthen' his body.
1. Scientists are responsible for removing plasmids, small rings of DNA, from bacterial cells.
2. The Enzymes cut open the plasmid DNA. The same enzyme removes the human insulin gene from its chromosome.
3. The human insulin gene attaches the open ends of the plasmid to form a closed ring.
4. Some bacterial cells take up the plasmids that have the insulin gene.

5. When cells reproduce, the news cells will contain copies of the engineered plasmid. The foreign gene directs the cell to produce human insulin.</span>
Explanation:
Given that,
Input force on a simple machine, F = 2 N
The output force on a simple machines, F' = 4 N
The ratio of the output force to the input force of any simple machines is called its mechanical advantage. Mathematically, it is given by :
Putting the value of F and F' in above equation. We get :
m = 2
So, the mechanical advantage of the simple machines is 2. Hence, this is the required solution.
