Answer:
The fraction of kinetic energy lost in the collision is 0.25 .
Explanation:
We know , momentum will be conserved along x direction .
Therefore ,
Now , fraction lost in kinetic energy is :
Therefore , the fraction of kinetic energy lost in the collision is 0.25 .
Answer:
Microwaves fall in the range of the EM spectrum between radio and infrared light.
Explanation:
Just because there is more mass in a certain substance doesn’t mean it’s density will change. In this case, water, will not change density simply because there is more of it. I.e the ocean. The bottom of the ocean may have more pressure to it because of the weight of the water above it but if you were to take a cup of it and take it to the surface it wouldn’t sink.
