Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four. If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.
I guess it’s d) isobaric mate correct me if I am wrong :D
Answer:
15
Explanation:
displacement = initial position - final position
The Coulomb's law equation is F = Kq₁q₂/r².
<h3>
What is Coulomb's law?</h3>
This is the law that relates the product of two charges to the square of distance between the two charges.
Coulomb's law states that the force of attraction or repulsion is directly proportional to the product of the charges and inversely proportional to the square of distance between the charges.
<h3>Coulombs' law equation</h3>
The equation of Coulomb's law is given as;
F = Kq₁q₂/r²
where;
- K is Coulomb's constant, Nm²/C²
- q₁ is the first charge, C
- q₂ is the second charge, C)
- r is the distance between the charges, m
Thus, the Coulomb's law equation is F = Kq₁q₂/r².
