Answer:
A latching relay
Explanation:
A latching relay is a subtype of electromechanical or electromagnet switch. It is a type of relay that maintains its position even after the power is removed. The reason why its used is because they allow a control of circuit by simply providing a single pulse to the relay control circuit.

Explanation:
magnesium is not a good conductor has some free electrons but it is not used that much in the industries because of other better alternatives.
You can tick number 5 as wlee. Good luck
Answer: Energy can be involved in disconnecting or connecting atoms to each other as the energy is used to break the bonds between the atoms ,so the reaction could proceed.
Explanation:<u> The statement can be well explained by the Planck's quantum theory , which states -:</u>
- In the form of small energy packets known as quanta of energy, energy is not released continuously, but discontinuously.
- The energy of each quantum is directly proportional to radiation frequency, i.e. E is directly proportional to v, where v is frequency E = hv, where h is the proportionality constant known as the constant of Planck.
- Any integer quanta will be the total energy of the radiation emitted or absorbed. Let the 'E' be the total radiation energy. So, when n is an integer, E'=nhv.
Hence, the given answer is based on the Planck's Quantum theory.
Answer:
Chemical Properties. The chemical properties of matter are those characteristics that give it the ability (or inability) to undergo a chemical change—a change in composition. ... Combustibility (how readily a substance can burn) is an example of a chemical property. For example, wood burns readily, forming ash and smoke.

Answer:
Ksp = 4.9 E-9
Explanation:
solubility: S S S
⇒ Ksp = [ Zr²+ ] * [ CrO4²- ]
⇒ Ksp = S * S = S²
⇒ Ksp = ( 7.0E-5)²
⇒ Ksp = 4.9E-9
