Answer:
True
Explanation:
- A conservative force is a force whose work done does not depend on the path taken, but only on the final and starting point.
- The mechanical energy of an object is defined as the sum of the kinetic energy (K) and the potential energy (U): E = K + U
- The law of conservation of energy states that, in case only conservative forces are acting on the object, the mechanical energy of the object E is conserved
- In case non-conservative forces are acting on the object, the mechanical energy is no longer constant. An example of non-conservative force is the force of friction: when the force of friction is acting on a car in motion, the car is slowed down by the effect of the force, losing some of its kinetic energy, K. If the car is travelling on a flat road, then its potential energy U does not change: this means that the mechanical energy of the car, E, is decreasing, so it is no longer conserved.
False, lightning is not an <span>example of matter in a liquid state. Rather, it is an example of matter in a state of plasma. </span>It<span> is a form of matter in which many of the electron s wander around freely among the nuclei of the atoms. Hope this answers the question.</span>
Answer:
Convection
Explanation:
Convection is heat transfer due to a density differential within a fluid. As water's temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes more dense and sinks.
