Answer:
The distance between the tip of her nose from the center of the crystal ball is 14.3 cm.
Explanation:
Given that,
Charge, 
The end of her nose experiences an electric field strengths of 2200 N/C
It is required to find the distance between the tip of her nose from the center of the crystal ball. The formula of the electric field is given by :

r is distance

So, the distance between the tip of her nose from the center of the crystal ball is 14.3 cm.
Answer:
The mass is 16 [g]
Explanation:
We have to remember the formula that defines density, which mentions that the density is equal to mass divided by the volume.
![Density = mass / volume\\where:\\density = 2[\frac{g}{cm^{3} } ]\\Volume = 8 [cm^{3}]](https://tex.z-dn.net/?f=Density%20%3D%20mass%20%2F%20volume%5C%5Cwhere%3A%5C%5Cdensity%20%3D%202%5B%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%20%7D%20%5D%5C%5CVolume%20%3D%208%20%5Bcm%5E%7B3%7D%5D)
Now we clear the mass:
![mass= density*volume\\mass = 2[\frac{g}{cm^{3} }]*8[cm^{3} ]\\mass = 16 [g]](https://tex.z-dn.net/?f=mass%3D%20density%2Avolume%5C%5Cmass%20%3D%202%5B%5Cfrac%7Bg%7D%7Bcm%5E%7B3%7D%20%7D%5D%2A8%5Bcm%5E%7B3%7D%20%5D%5C%5Cmass%20%3D%2016%20%5Bg%5D)
Answers:
a) 30 m/s
b) 480 N
Explanation:
The rest of the question is written below:
a. What is the final speed of the falcon and pigeon?
b. What is the average force on the pigeon during the impact?
<h3>a) Final speed</h3>
This part can be solved by the Conservation of linear momentum principle, which establishes the initial momentum
before the collision must be equal to the final momentum
after the collision:
(1)
Being:


Where:
the mas of the peregrine falcon
the initial speed of the falcon
is the mass of the pigeon
the initial speed of the pigeon (at rest)
the final speed of the system falcon-pigeon
Then:
(2)
Finding
:
(3)
(4)
(5) This is the final speed
<h3>b) Force on the pigeon</h3>
In this part we will use the following equation:
(6)
Where:
is the force exerted on the pigeon
is the time
is the pigeon's change in momentum
Then:
(7)
(8) Since 
Substituting (8) in (6):
(9)
(10)
Finally:
