Answer:
D. Friction
Explanation:
Friction is a force that opposes motion. So a perpetual motion machine can never be built because it is impossible to eliminate frictional force. It can only be reduced
The two types of motion exerted in bicycle are:
1. rotary motion
2. linear motion
Answer:
speed = 3600 kilometers per hour
= 3600 km/h
speed = 1000 meters per second
= 1000 m/s
Answer From Gauth Math
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.
