Answer:
The direction will be 
and the distance 250.75km.
Explanation:
Let's say A is the displacement vector which represents the first 170km and B the one for the next 230km. Then the components of these vector will be:
The vector which point from the origin to the final position of the plane will be R=A+B. We sum components on <em>x </em>and <em>y </em>independetly (vector property):
If 
is the direction of R then:
⇒ 
⇒ 
.
The distance will be given by the magnitud of the vector R:
⇒ 
.
1 Kg = 1,000g
Therefore 1.33 × 10^-7 g = 1.33 × 10^-10 kg
1m³ = 1,000,000cm³
Therefore 1 cm³ = 1 × 10^-6 m³
Dividing the mass per unit volume you get:
(1.33 × 10^-10 kg) ÷ (1 × 10^-6 m³)
= 1.33 × 10^(-10--6) = 1.33 × 10^(-10 + 6) = 1.33 × 10^-4 kg/m³
Density = 1.33 × 10^-4 kg/m³
True, when charging a secondary cell, energy can be stored within a dielectric material using an electric field.
<h3>Relationship between dielectric material and electric field</h3>
The electric field in a capacitor separates the negative and positive charges in the dielectric material, this causes an attractive force between each plate and the dielectric.
The dielectric material can store electric energy due to its polarization in the presence of external electric field, which causes the positive charge to store on one electrode and negative charge on the other.
Thus, when charging a secondary cell, energy can be stored within a dielectric material using an electric field.
