Answer
</u>
The impulse on the second trial is smaller is smaller than in the first trial.
<u>Explanation
</u>
Impose of a body is that change in momentum during a time interval. If the change of momentum takes longer then, the impulse of a force is less. I a moving object hits a hard surface the rate of change of momentum is very high. e.i in the first trial, the egg breaks because it hits the hard surface(ground).
In the second trial, the foam cushion absorbs the shock and prolongs the time of impact with the egg hence decreasing the impulse.
Answer:
light doesn't need a medium through which to travel because the speed of light is experimentally constant
Answer:
It is not correct because the amplitude of the waves can be bigger than others and the graph can be going up and down
