Choose the law that best explains the example:

pushing off the wall at the ice skating rink and going the opposite direction is an example of newton’s

group of answer choices

3rd law

none of these

2nd law

1st law

3rd law

Explanation:

First law of Newtons :

 Newton's First Law states that, unless an external force acts on it, an object will remain in a straight line in rest or uniform motion.  

The second law of Newtons :

The second law states that an object's acceleration depends on two variables-the net force that acts on the object and the object's mass.

The change in the linear momentum of the object is equal to the force.

Third law of Newtons :

This law states that every action has its reaction with the same magnitude but in the opposite direction.

When we push the wall , then the wall does not move because the wall is fixed but we skid opposite to the direction of applied force because wall offers an opposite force on our body.

Therefore the answer is "third law".

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
