Answer:
When x = 2.8 cm, 
When x = 5.5 cm, 
when x = 7.3 cm, 
When x = 11.0 cm, 
Explanation:
According to Biot-Savart law,
.......................(1)
R = 11.0 cm = 0.11 m
I = 17.0 A
N = 300 turns

When x₁ = 2.8 cm = 0.028 m

When x₂ = 5.5cm = 0.055 m

When x₃ = 7.3 cm = 0.073 m

When X₄ = 11.0 cm = 0.11 m

Answer:
The 1st Answer
Explanation:
Because kinetic energy is the energy which a body possesses by virtue of being in motion. So if the velocity of the object (cannonball in this case) decreases than so would the kinetic energy

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.
