The thing that they should do to prevent fatigue and maintain the quality of chest compressions is: <span>Change positions every 2 minutes.
Giving a CPR require someone to stay in one place and doing the same movement over and over again (such as chest compression)
IF we do a CPR more than 2 minute, our body will start to feel fatigue that could decrease the quality of our CPR. If we have 2 persons doing a cpr, changing position every 2 minutes will help maintaining this quality.</span>
Are there any answer choices you can give us??
Momentum is a vector quantity, which means it has both magnitude and direction. When two objects collide, the direction of motion of the objects after collision is determined by the direction of the momentum of the object with the larger momentum. Therefore, the answer is B. the larger object's momentum<span>.</span>
Atrophy, hope this helps :)
