Depth perception is the way in which some animals, such as humans, can tell if a object is close or far away from them.
Answer:
a) Ф = 0.016 N / C m
, b) q_{int} = 0.14 10⁻¹² C
Explanation:
a) For this problem we use Gauss's law
Ф = E .ds = /ε₀
The camp is in the x direction so it has no flow through the cylinder walls.
Ф = E A
The area of a circle is
A = π r
Ф = E π r
Ф = (x- 3.6) r
Let's calculate
Ф = (3.7 -3.6) 0.16
Ф = 0.016 N / C m
b) we clear from Gauss's law
q_{int} = Ф ε₀
Where the flow is on both sides, on the face at x = 0 the flow is zero
q_{int} = 0.016 8.85 10⁻¹²
q_{int} = 0.14 10⁻¹² C
Answer:
the motorcycle travels 42.4 meters until it stops.
Explanation:
Vi= 18 m/s
Vf= 0 m/s
t= 4.7 sec
Vf= Vi - a*t
deceleration:
a= Vi/t
a= 18m/s / 4.7 sec => a=-3.82 m/s²
x= Vi*t - (a * t²)/2
x= 42.4m
