I believe the answer for 1) is
PEgrav = mass • g • height
PEgrav = m *• g • h
The answer is : Low frequency sounds
place theory is a theory of hearing which states that our perception of sound depends on where each component frequency produces vibrations along basilar membrane, which is very sensitive to low frequency sound
Answer:
4.5 m/s
Explanation:
ignore the mass, it doesn't matter
speed is defined as distance/time
both are given so just divide the two
