Answer:

Explanation:
= Permittivity of free space = 
A = Area = 
d = Thickness = 
k = Dielectric constant = 5.4
V = Voltage = 86.2 mV
Charge is given by

The charge on the outer surface is 
Answer:
<em>10.90km</em>
Explanation:
Magnitude of the total displacement is expressed using the equation
d = √dx²+dy²
dx is the horizontal component of the displacement
dy is the vertical component of the displacement
dy = -6.7sin27°
dy = -6.7(0.4539)
dy = -3.042
For the horizontal component of the displacement
dx = -4.5 - 6.7cos27
dx = -4.5 -5.9697
dx = -10.4697
Get the magnitude of the bicyclist's total displacement
Recall that: d = √dx²+dy²
d = √(-3.042)²+(-10.4697)²
d = √9.2538+109.6146
d = √118.8684
<em>d = 10.90km</em>
<em>Hence the magnitude of the bicyclist's total displacement is 10.90km</em>

The inertia of the ketchup will keep it from moving if it isn't too tightly adhered to the sides of the moving bottle.
Answer:
The pressure difference between two pipe is
Pa
Explanation:
Density

Speed in one pipe

Speed in second pipe

According to the bernoulli equation,
The pressure difference is given by,


![P_{2} - P_{1} = \frac{1}{2} \times 1165 \times[ (4.53)^{2}- (1.77)^{2}]](https://tex.z-dn.net/?f=P_%7B2%7D%20-%20P_%7B1%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%201165%20%5Ctimes%5B%20%284.53%29%5E%7B2%7D-%20%281.77%29%5E%7B2%7D%5D)
Pa
Therefore, the pressure difference between two pipe is
Pa
