An unbalanced force is required to accelerate an object according to Newton's Second Law of Motion.
<h3>
What does Newton's Second Law of Motion state?</h3>
It states that the force applied to the object is equal to the product of mass and acceleration.
- An object will accelerate when the net force applied on the object is more than zero or unbalanced.
- The acceleration is the change in the direction or speed of the object. To achieve acceleration the force must be greater in a direction.
- When force is greater in one the object move in that direction which is known as acceleration.
Therefore, an unbalanced force is required to accelerate an object according to Newton's Second Law of Motion.

Answer:
The current in the wire = 39.53 A.
Explanation:
The given cross -sectional area of the wire = 1.35 .
The number of electrons flowing in the wire at any point is
= 5.41 electrons.
The charge of an electron is known to be =
The electronics flow across the wire for a time of, t = 2.19 seconds.
The current in the wire = (number of electrons) ×
= 5.41 ×
= 39.53 A.
The formula for current is actually, i = .
The (number of electrons )×(charge of an electron) will equal the total charge flowing through the wire in the given time = 2.19 seconds.
The current in the wire = 39.53 A.

b
Explanation:
because I dont know I guess I learned it in school
Friction is a force that oppose other forces and can slow them down
