Which refers to the change of pitch heard when the source of the sound approaches and then moves away from a stationary person? Doppler effect volume resonance effect vibration
2 answers:
<h2><em>The Doppler effect is a change in the frequency of sound waves that occurs when the source of the sound waves is moving relative to a stationary listener. As the source of sound waves approaches a listener, the sound waves get closer together, increasing their frequency and the pitch of the sound.</em> </h2><h2><em>HOP</em> E IT HELPS </h2><h2>THANK YOU </h2>

Answer:
A dissipates more power.
Explanation:
In a series circuit, the current is the same at any point in it. The power dissipated in any resistor follows Joule's law, as follows:
So, for a given current, the power is directly proportional to the resistance of the resistor. In this case, as resistor A has twice the resistance of resistor B, A dissipates twice more power than B.

The time it takes for the ball to reach its maximum height can be calculated using
since
Answer:
85.556metres
Explanation:
Using pythagorean theorem
C²=A²+B²
we have c as the hypotenuse vector A thus:
93.8²=A²+38.4²
93.8²-38.4²=A²
8794.44-1474.56=A²
7319.88=A²
A=85.556
