No, she has it backward. Waves interfere with each other and reflect off objects. When two waves overlap their amplitudes add. If they have the same sign this addition is constructive, meaning the amplitudes grow. If they have opposite signs this constitutes subtraction and the waves can partially, or completely cancel. This is known as interference. Reflection occurs when waves travel from one medium to another. If the wave impedance of the new medium is different (which it generally is) there will be a partial, or even total, reflection.
Answer:
2.5 m/s
Explanation:
Mechanical energy is the sum of the potential and kinetic energy.
E = PE + KE
E = mgh + ½mv²
172.1 J = (7.26 kg) (9.8 m/s²) (2.1 m) + ½ (7.26 kg) v²
v = 2.5 m/s
Explanation:
new non law neutron means neutral then it's important that baseball and softball features small respectable range of masses soft it means that when a ball hits anything hard it comes back by the Newton Law if the baseball is big and the small boy small and then if the contract with each other they ignore triple so when a ball hits the wall if the comeback because of the Mutants and when a big ball if we throw it to the wall it doesn't come that it comes back but in a very low way because it contains less neutrons in it if it is helpful please share with me
Hello <span>Andijwiltbank

Question: <span>Often what one expects to see influences what is perceived in the surrounding environment. True or False?
Answer: True
Reason: What we observe about the environment decides what we believe about it and how we react.
Hope This Helps :-)
