Answer:
Explanation:
According to newton's law , force between mass m₁ and m₂ at distance x is given by the following expression
F = G m₁m₂ / x²
differentiating F with respect to x , we have
dF / d x = ₋2G m₁m₂ / x³ .
Rate of reduction of force ∝ 1 / x³
B, he has to apply less force to lift the box because the mass has decreased.
The equation for force is
F=ma
If m is decreased by half, then f decreases as well. It takes less force to push a lighter object across the floor.
Answer:
open source Software
Explanation:
An open source software can be any software made available within an open source license which means that anyone can access its source code, see that it was created and, as the question says, "study, change and improve it."
This is contrary to copyrighted or closed source software where you would require a license to use the software, however, we can not see or amend in the "building blocks" (i.e. code)
