Part 1: a magnetic levitation or maglev train rides rails without touching them. explain how this works using your data. include the appropriate magnet drawing in your answer. part 2: two objects are near a bar magnet. one is about 1 cm away, while the other is 6 cm away. compare and contrast the magnetic force that affects each object. use your data to answer the question

Sorry i don’t know what to do

Answernewton's second law,says that when a contant force acts on a massive body, it causes it to accelerate

We can not use the law of conservation of energy here. we will use the law of conservation of momenta. we will break into two components, the x component will represent east, and y component will represent north.solving this system will give us the velocity of the third mass.we can plug this backi into the first equation: with this angle we can now calculate the velocity:

The scientist was trying to demonstrate that humans can introduce their own biases into an experiment. bias is a prejudice in favor of one thing compared with the another.in this case, the bias is believing that mice with higher intelligence would solve the maze better.  bias in science should be avoided as it is not desirable that research becomes influenced by scientists personal beliefs.
