True or false: You can make a pulse travel at a faster speed without changing the shape or size of the pulse.

False

Explanation:

A Larger pulse with more energy means that the wave has a large amplitude. As in the given question, both the waves are travelling in the same medium, hence their speeds will remain the same and therefore the larger pulse will not overtake the smaller pulse. Remember the amplitude of a wave does not affect the speed at which the wave travels.

answer; ///(74) degrees is your answer..

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .
