Answer:
Net Force Formula: F1+F2+F3...+FN
*(MAKE SURE YOU MAKE NOTE OF THE NEGATIVE FORCES AND SUBTRACT THEM!)*
Explanation:
Top left: 17N+25N+25N-42N= 25N
Top right: 65N+200N-65N-150N-200N= 150N
Bottom left: 189N+123N+284N-96N-188N-312N= 0N
Bottom right: 34N+77N-12N-34N= 65N
I hope this helps! :))
Answer:
The density of salt water is more than that of density of fresh water, so so salt and fresh water makes a difference in floating of ships.
Answer:
it is a force
Explanation:
a force is a push or a pull
I believe this is what you have to do:
The force between a mass M and a point mass m is represented by

So lets compare it to the original force before it doubles, it would just be the exact formula so lets call that F₁
So F₁ = G(Mm/r^2)
Now the distance has doubled so lets account for this in F₂:
F₂ = G(Mm/(2r)^2)
Now square the 2 that gives you four and we can pull that out in front to give
F₂ =
G(Mm/r^2)
Now we can replace G(Mm/r^2) with F₁ as that is the value of the force before alterations
now we see that:
F₂ =
F₁
So the second force will be 0.25 (1/4) x 1600 or 400 N.
