Answer
Integral EdA = Q/εo =C*Vc(t)/εo = 3.5e-12*21/εo = 4.74 V∙m <----- A)
Vc(t) = 21(1-e^-t/RC) because an uncharged capacitor is modeled as a short.
ic(t) = (21/120)e^-t/RC -----> ic(0) = 21/120 = 0.175A <----- B)
Q(0.5ns) = CVc(0.5ns) = 2e-12*21*(1-e^-t/RC) = 30.7pC
30.7pC/εo = 3.47 V∙m <----- C)
ic(0.5ns) = 29.7ma <----- D)

The speed of the falcon is 144 km/h
Explanation:
The speed of a body is a scalar quantity telling how fast the object is moving, without giving any information about its direction.
It can be calculated as:
![speed = \frac{d}{t}](https://tex.z-dn.net/?f=speed%20%3D%20%5Cfrac%7Bd%7D%7Bt%7D)
where
d is the distance covered
t is the time taken
In this problem, the falcon has a speed of
![speed = 40 m/s](https://tex.z-dn.net/?f=speed%20%3D%2040%20m%2Fs)
We want to convert it into km/h. Let's keep in mind that:
1 km = 1000 m
1 h = 3600 s
Therefore, we convert as follows:
![speed = 40 \frac{m}{s} \cdot \frac{3600 s/h}{1000 m/k}=144 km/h](https://tex.z-dn.net/?f=speed%20%3D%2040%20%5Cfrac%7Bm%7D%7Bs%7D%20%5Ccdot%20%5Cfrac%7B3600%20s%2Fh%7D%7B1000%20m%2Fk%7D%3D144%20km%2Fh)
