Answer:
Electromagnetic spectrum
Explanation:
Telescopes are used by observers to monitor various electromagnetic radiation. Only one component of the visible radiation can be observed by each type of instrument. Telescopes, ultraviolet telescopes, optical celestial objects, and other types of telescopes are available.
Answer:
The easiest way to identify a double displacement reaction is to check to see whether or not the cations exchanged anions with each other.
Explanation:
if the states of matter are cited, is to look for aqueous reactants and the formation of one solid product (since the reaction typically generates a precipitate).
The water cycle renews water supplies by moving water from the oceans, as freshwater, to land
This is a redox reaction.
Cu²⁺ + 2e⁻ = Cu⁰ copper is the oxidizing agent
Fe⁰ - 2e⁻ = Fe²⁺ iron is the reducing agent
The definition of the speed of light is exactly 299,792,458 meters per second, so to find how far it travels in a time period, multiply the speed of light times the time. Aka c=299,792,458m/s where c is speed of light, m is meters, and s is seconds. So for example to find how far light travels in 5 seconds, multiply by 5.
