True or false science questions?

1. True or False?





Momentum is a property of an object and cannot be transferred from that object to another.





2. True or False?





Acceleration is defined as the rate of change in position.





3. True or False?





The more dense area of a compressional wave is calles a rarefaction.(s/p)





4. True or False?





When two or more waves combine to become a new wave, the process is called interference.





5. What is the Keppler effect?True or false science questions?
Momentum is a property of an object and cannot be transferred from that object to another.





False. Momentum is frequently transferred between objects in collisions.





Acceleration is defined as the rate of change in position.





False. The time rate of change of position is called ';velocity.'; Acceleration is the time rate of change of velocity.





The more dense area of a compressional wave is calles a rarefaction.(s/p)





False. The least dense area of a wave is a rarefaction. The more dense area is called a compression.





When two or more waves combine to become a new wave, the process is called interference.





True.
