Answer:
A.......
Explanation: The sun is the main source of energy
Answer:
z≅3
Atomic number is 3, So ion is Lithium ion (
)
Explanation:
First of all
v=f*λ
In our case v=c
c=f*λ
λ=c/f
where:
c is the speed of light
f is the frequency

Using Rydberg's Formula:

Where:
R is Rydberg constant=
z is atomic Number
For highest Energy:
n_1=1
n_2=∞

z≅3
Atomic number is 3, So ion is Lithium ion (
)
The equivalence point of a titration is equal to its stoichiometric equivalents of analyte and titrant.
Depending on the concentration of titrant we could be adding little excess of it and this may result in persistence of color of solution. After continuous stirring for a while the excess titrant may react with dissolved CO₂ in air and thus decolorizing the solution.

Answer:
A space station
Explanation:
A space station provides an avenue for scientist to orbit the space and carryout scientific findings. Most space stations are usually controlled under agreement between different countries. The international space station is one such example.
A rover is usually a robotic device that has been pre-programmed and equipped with state of the art devices to carryout explorations on their own.
Most space observations are usually powerful telescopes on the earth surface that monitors events in space.
A satellite is a body that orbits another.
