As Clinton walks he pushes his shoe against the track.
Which of the following best describes the reaction force to Clinton's shoe pushing against the track?
OA. The track pushes back on Clinton's shoe with the same force.
ОВ.
The track pushes in the same direction as Clinton's shoe with the same force.
OC. The track pushes against gravity with the same force.

The track pushes in a different direction with a different force.

Answers

Answer:A:The track pushes back on Clinton's shoe with the same force.

Explanation:According to Newton's third law of motion, for every action force there is an equal and opposite reaction force. In this case, the action force is Clinton's shoe pushing on the track. As this happens, there is an equal and opposite reaction force in which the track pushes back on Clinton's shoe with the same force.

Do you think we might have problems with not enough water to supply our needs (water scarcity) in the
ture? Why or why not? If you answered yes, what might the causes be?

Answers

Answer:

Water scarcity (water stress or water crisis) is the lack of fresh water resources to meet the standard water demand. Humanity is facing a water crisis, due to unequal distribution (exacerbated by climate change) resulting in some very wet and some very dry geographic locations, plus a sharp rise in global freshwater demand in recent decades driven by industry. Water scarcity can also be caused by droughts, lack of rainfall, or pollution. This was listed in 2019 by the World Economic Forum as one of the largest global risks in terms of potential impact over the next decade.[1] It is manifested by partial or no satisfaction of expressed demand, economic competition for water quantity or quality, disputes between users, irreversible depletion of groundwater, and negative impacts on the environment.[2] Two-thirds of the global population (4 billion people) live under conditions of severe water scarcity at least 1 month of the year.[3][4][5][6] Half a billion people in the world face severe water scarcity all year round.[3] Half of the world's largest cities experience water scarcity.[5]

A 3500 N is force is applied to a spring that has a spring of constant of k= 14000 N/m. How far from equilibrium will the spring be displaced?

Answers

Answer:

the spring be displaced by 25.0 cm

Explanation:

The computation is shown below:

As we know that

F= -K × x

So,

[tex]x = \frac{-F}{K}[/tex]

Now  

[tex]x = \frac{-3500}{14000} \\\\[/tex]

= -0.250m

= 25.0 cm

Hence, the spring be displaced by 25.0 cm
