What we are seeing now is an "Emission line spectrum".
Explanation:
- When an electrified glass tube containing thin neon gas is turned on, the tube will glow with a rich red color which are nothing but the line emission spectrum.
- Emission spectrum are nothing but the spectrum that contains frequencies of electromagnetic radiations that might get emitted due to the transition of atom from a higher energy state to lower energy state.
- If the emitted radiation is in the form of light, It is known as light emission spectrum and In the above mentioned sculpture you can see that neon gas is electrified which in turn produces rich red color and hence we can conclude that the obtained spectrum is Emission line spectrum.
Answer: The stratification of earth into its geologic layers was brought about by th e formation of the earth iron core.
Explanation:
If it happens to be cruising along at 5 meters per second (about
11 miles per hour), then it covers 10 meters in 2 seconds without
any acceleration at all.
2) What must be connected for an electrical current to flow in a simple current?
<em>d.moving magnets,conductors, load to do work
</em>
here moving magnets will work as generator and conductors is used as connectors.
5)What is the purpose of a load in a circuit?
<em>c.provide resistance to keep the voltage strong
</em>
Load will provide the resistance to the circuit and help to build the voltage across it
6) What cause an electric current from a generator
<em>d.Magnets and conducting wires move near each other
</em>
here when magnets move near wires then it will induce the electric current and behaves like generators
7) What do all generators have in common
<em>b.they transform mechanical into electrical energy
</em>
They have magnets and rotating coils which will convert magnetic energy to electrical energy
8) How can we measure electrical current
<em>b.the pressure force is voltage;the # of electrons moving is amperes
</em>
this voltage and number of electrons will help to calculate current
answer:
liquids have he ability to change shape
liquids flow even with some resistance
liquids have a definite volume
liquids have molecules that slip past each other
