Answer:
Unfortunately, you can rarely identify a mineral only by its color. Sometimes, different minerals are the same color. For example, you might find a mineral that is a gold color, and so think it is gold. But it might actually be pyrite, or “fool's gold,” which is made of iron and sulfide.
Explanation:
Answer:
the endocrine system and the nervous system are the two major regulating and communicating systems of the body. During rest and exercise, the nervous system along with endocrine system regulate the body mechanism to initiate the maintenance of Homeostasis in the body.
both endocrine and nervous system are both together involved in the transmission of chemicals signals which are important for physiological processes in the body . The difference is that endocrine system uses Hormones while nervous system uses neurotransmitters for chemical signalling.
The main area of the brain where these system work together and perform their function collectively is Hypothalamus where they signal each other when they receive proper stimulus.
Amplitude
Energy
Explanation:
The amplitude is the height of the wave and measures the amount of energy it carries.
Amplitude of a wave is the maximum amount of displacement of wave from rest.
The energy of the a wave is the amount of disturbance a wave transmits.
- The amplitude of a wave is the wave height.
- It measures the vertical height through which a wave passes through.
- Waves that have a high vertical displacement i.e high amplitude carries a lot of energy.
E = kA²
where E is wave energy , k is the wave number and A is the amplitude of the wave.
