How does Newton's second law of physics apply to lifting weights? O A. Lifting weights requires the proper form and net force.
OB.
Without force or motion, the weights are an unbalanced force.
C. It requires more force to move weights, and this builds muscles.
OD. Weights are an immovable object, and the force is provided by muscles.

C

Explanation:

Whenever we lift weights, we are exerting force against the barbell. In physics, we measure force using Newton's Second Law of Motion via the equation f = ma, or put differently, force is equal to mass multiplied by acceleration. To generate more force, we must either increase mass or acceleration (or both).

answer:

Our freedom of choice in a competitive society rests on the fact that, if one person refuses to satisfy our wishes, we can turn to another. But if we face a monopolist we are at his absolute mercy. ... There is no consensus as to whether an increase in economic freedom of choice leads to an increase in happiness.

Explanation:

It is so important to understand that we are all making choices all the time, even when we chose not to choose we have still made a choice. It is our choices that determine our experiences. ... Unless we are willing to take full responsibility for ourselves and the choices we make, we have no control over our lives
