Answer:
Magnitude of kinetic force is the product of the normal force and the coefficient of kinetic friction.
Explanation:
The kinetic frictional force is the force which is experienced in the moving surfaces of bodies.The magnitude of the force is affected by the coefficient of kinetic friction between the material of two bodies in contact. Mathematically, it is expressed as;
Fk=μk*η
where;
- Fk=force of kinetic friction
- μk=coefficient of kinetic friction
- η=normal force
Answer:
Since the nearsighted eye over converges light rays, the correction for nearsightedness is to place a diverging spectacle lens in front of the eye. This reduces the power of an eye that is too powerful.
Explanation:
Applying Newton's Second Law of Motion, the acceleration of the ball is 16.8 
<u>Given the following data:</u>
- Acceleration due to gravity = 9.8

To find ball's acceleration, we would apply Newton's Second Law of Motion:
First of all, we would determine the net force acting on the ball.

× 
Downward force = 4.9 N

Net force = 8.4 N
Mathematically, Newton's Second Law of Motion is given by this formula;

<em>Acceleration = 16.8 </em>
<em />
Therefore, the acceleration of the ball is 16.8

The output voltage is 10 times the input voltage.
So the output coil has 10 times as many turns as the input coil has.
That's how transformers work.
Complicated, huh !
10 times 1,000 turns = <em>10,000 turns</em>
We do not know how how fast the car was going
