Answer:
decreases at a constant rate
Explanation:
At A, the vertical velocity component is positive. At B, it is 0. At C, it is negative.
So the vertical velocity component is decreasing, specifically at the rate of the acceleration due to gravity.
Answer ) Sound level equation
The intensity of a sound wave is related to its amplitude squared by the following relationship: I=(Δp)22ρvw I = ( Δ p ) 2 2 ρ v w . Here Δp is the pressure variation or pressure amplitude (half the difference between the maximum and minimum pressure in the sound wave) in units of pascals (Pa) or N/m2.
It’s okay we can be friends :)
