The minimum resting energy expenditure of an awake alert person is referred to as resting metabolic rate (RMR). It represents the amount of energy required to maintain basic physiological functions such as heartbeat, breathing, and body temperature while at rest.
A source is a device that provides electrical energy, while a battery is a specific type of electrical energy source that stores chemical energy and converts it to electrical energy. Think of a battery as a portable source of energy that can be used in various electronic devices, while a source can refer to any device that generates electricity, such as a power outlet or generator.
No, kinetic energy is not a source of activation energy. Activation energy is the minimum amount of energy required to start a chemical reaction, while kinetic energy is the energy of motion possessed by an object.
The energy is converted into other forms as the rock comes to a stop. Some of the energy is dissipated as heat due to friction with the air and the surface it's resting on, while the rest of the energy is transferred to the surroundings.
Sound is determined by the amount of energy the source produces. A louder sound is created by a source that produces more energy, while a quieter sound is produced by a source with less energy. The amplitude or intensity of the sound wave also plays a role in determining the volume of the sound.
