I think it’s cause no change i think
A region around a charged partical or object. Let me know if this works. Hope I could help you.
Yes. Kinetic energy is a form of mechanical energy and friction will turn that kinetic energy into heat.
Answer:
90 degrees
Explanation:
the answer is 90 because angle a has a square on the angle which means it is 90 degrees
Answer:
Option C
100 J
Explanation:
Kinetic energy, KE is given by
where m is the mass and v is the velocity
Substituting 50 Kg for mass, m and 2 m/s for velocity v then we obtain

Therefore, the child's kinetic energy is equivalent to 100 J
