Explanation:
a scientific theory is a well substantiated explanation of some aspect of the nature world, based on a body of facts that have been repeatedly confirmed through observation and experiment. search fact-supported theories are not "guesses" but reliable account of the real world .
Answer:
The total kinetic energy of the system before the collision is 57 Joules.
Explanation:
Given that,
Mass of first block,
Speed of first block,
Mass of second block,
Speed of first block,
We need to find the total kinetic energy of the system before the collision. It is equal to the kinetic energies of both the blocks. It is given by :
So, the total kinetic energy of the system before the collision is 57 Joules.
Answer:
the law of motion
Explanation:
because the wheels are moving it means motion i am not sure which number law it is but I believe that it is 2nd but u should look it up to be safe
Answer: Im not entirly sure but I think It's D all the above. I think all but B because I never really heard of that but if you look in our history I think that happen im not sure I would wait untill you know that somone knows for sure.
