Answer:
Explanation:
The definition of the intensity in terms of power is given by:
Where:
- P is the power
- A is the area
If the sound emits uniformly in all directions and that there are no reflections, we can assume the geometry of the wave sound is spherical.
Let's recall the area of a sphere is
To the first location we have:
and to the second location we have:
Now, we can divide each intensity to find the second intensity.
I hope it helps you!
We have that the initial velocity is mathematically given as
V1=86.4m/s
<h3>Velocity</h3>
Question Parameters:
- A 0.05 kg arrow
- Is fired at a velocity towards a 1.2 kg apple.
- The arrow sticks in the apple and both move at 3.6m/s.
Generally the equation for the Conservation of momentum is mathematically given as
M1V1=M2V2
Therefore
0.05*V1=1.2*3.6
V1=(1.2*3.6)/0.05
V1=86.4m/s
