Which of the following has the greatest impulse? Which has the greatest momentum? a. A 6000 kg elephant charging at a constant velocity of 11 m/s.
b. A 200 gram bullet fired from rest to 300 m/s.
c. A 18,000 kg fire truck parked on the street.

In which of these cases are the two wave points considered to be in phase with each other?

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.

The law of entropy can also be called the law of increasing disorder, but this law seems to contradict the existence of living organisms that are able to organize chemicals into organic molecules. prepare for a class debate on the validity of the following arguments: a. living things are not subject to the laws of thermodynamics. b. the increase in the universe's entropy due to life processes is greater than the decrease in entropy within a living organism.
