Answer:
![V=23.3kV](https://tex.z-dn.net/?f=V%3D23.3kV)
Explanation:
Definition of the capacitance C, where a voltage V is applied and a charge Q is stored:
![Q=C*V](https://tex.z-dn.net/?f=Q%3DC%2AV)
We solve to find V:
![V=Q/C=0.14*10^{-3}C/6*10^{-9}F)=2.33*10^{4}V=23.3kV](https://tex.z-dn.net/?f=V%3DQ%2FC%3D0.14%2A10%5E%7B-3%7DC%2F6%2A10%5E%7B-9%7DF%29%3D2.33%2A10%5E%7B4%7DV%3D23.3kV)

Answer:
Magnitude of the hiker's total displacement = 3.5 km
Angle and direction of the hiker's total displacement = 22 degree south of west
Explanation:
The first Displacement in vector form is
= -4.5 cos 45i +4.5 sin 45j
= -3.182i + 3.182j
The second Displacement in vector form is
= -4.5j
The total displacement is ,
![s = s_1+ s_2](https://tex.z-dn.net/?f=s%20%3D%20s_1%2B%20s_2)
= -3.182i + 3.182j - 4.5j
=-3.182i-1.318j
The magnitude of the displacement is,
![s= \sqrt{(-3.182)^2 + (-1.318)^2\\](https://tex.z-dn.net/?f=s%3D%20%5Csqrt%7B%28-3.182%29%5E2%20%2B%20%28-1.318%29%5E2%5C%5C)
![s=\sqrt{10.125+1.7371}](https://tex.z-dn.net/?f=s%3D%5Csqrt%7B10.125%2B1.7371%7D)
![s=\sqrt{11.862}](https://tex.z-dn.net/?f=s%3D%5Csqrt%7B11.862%7D)
s= 3.444
The direction is,
![\theta = tan^{-1}(\frac{1.318}{3.182})](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20tan%5E%7B-1%7D%28%5Cfrac%7B1.318%7D%7B3.182%7D%29)
![\theta = tan^{-1}(0.4142)](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20tan%5E%7B-1%7D%280.4142%29)
![\theta = 22.49^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%20%3D%2022.49%5E%7B%5Ccirc%7D)
Answer:
130m
Explanation:
You just have to multiply velocity by the time traveled:
100m/s * 1.3s = 130m!
