The force between the two objects is 19.73 nN.
<u>Explanation:
</u>
Any force acting between two objects tends to be directly proportional to the product of their masses and inversely proportional to the square of the distance between the two objects. And this kind of attraction force between two objects is termed as gravitational force.
So if we consider 
and 
as the masses of both objects and let d be the distance of separation of two objects. Then the force between the two objects can be determined as below:
As gravitational constant 
, = 20 kg and = 100 kg, while d = 2.6 m, then
Thus, we get finally,
As we know, nano denoted by letter 'n' equals to 
So the force acting between two objects is 19.73 nN.
Hooke's Law states that the extension is directly proportional to the force applied so:
F/x = constant
F₁/x₁ = F₂/x₂
2 / 0.02 = 1600 / x₂
x₂ = 16 m
Elastic work = 1/2 Fx
= 1/2 * 1600 * 16
= 12.8 kJ

Answer:
Positions in Hockey: 6 players for each team on the ice
1 Goalie – the player in the goal who tries to stop the puck from going in the net.
1 Center – plays in between the two wings and is usually the best passer on the team
2 Wings – offensive players who plays on both sides of the center. They are usually goal scorers
2 Defensemen – main job is to play defense and help defend the goal
Passing Cues
1. Stick blade faces target
2. Puck in center of blade
3. Transfer weight rear to front as you pass
4. Use wrist movement to drive the puck
5. Follow through at target
Receiving Cues:
1. athletic position
2. catch puck with middle of blade and control
3. slow the puck when it contacts the stick by giving with it
Explanation:
Acceleration means any change in the speed or direction of motion.
