Answer:
Net force is the vector sum of forces acting on a particle or body. ... Its associated torque, the net force, becomes the resultant force and has the same effect on the rotational motion of the object as all actual forces taken together. It is possible for a system of forces to define a torque-free resultant force.
Explanation:
In a tug of war, a fat man pulls with a force of 100 N on one side, and a man pulls with 90 N on the other side. Compute the net force.
Solution:
Given:
Force F1= 100 N,
Force F2 = -90 N.
The net force formula is given by,
F_NET = F_1 + F_2F
N
ET=F
1
+F
2
F_NET = (100 ) +(– 90)F
N
ET=(100)+(–90)
F_NET= 10 NF
N
ET=10N
Therefore, the net force is 10 N.

Answer: Their final relative velocity is -0.412 m/s.
Explanation:
According to the law of conservation,
Putting the given values into the above formula as follows.
v = 
= -0.412 m/s
Thus, we can conclude that their final relative velocity is -0.412 m/s.
Answer is adaptation. An organism develops a trait over time to help survive in its environment called an adaptation. You could take a giraffe for example. A long time ago giraffes actually had short necks, but now since their food is higher they soon developed a longer neck and this is what we now see in the present. This goes for any artic animal. Polar bears and seals have a white fur adaptation to help them blend in with their environment. A chameleon changes colors in order to hide from predators and sneak up on prey. These are all adaptations
