This would be louder sound. Higher pitch would be represented by a more compressed wave that oscillates more times over a shorter period. Higher amplitude represents higher sound because the wave oscillates at the same speed, yet higher.
Hope this helped, and have a nice day!
C) doubling the mass doubles the acceleration
Answer:
From C to D, kinetic energy is transformed into
gravitational potential energy.
Velocity of the plane relative to the air = +400.0 m/s
Velocity of the air relative to the ground = -35.0 m/s (negative because it's moving opposite to the eastward direction)
Velocity of the plane relative to the ground = (velocity of the plane relative to the air) + (velocity of the air relative to the ground) = 365.0 m/s to the east
Answer:
milligrams
