d. all of the above

Answers

Nuclear power plants produce radioactivewaste that must be stored properly. It is very impossible for a nuclear power plantto have no waste at all since lots of chemicals are used to create the processas it gives energy to other machines. Nuclear energy can be used to power allof the above choices. Radioactive waste can not be released into local watersupplies since the wastes are very radioactive and may cause mutation to thefishes and bioaccumulation which will affect humans as well. It will also causeair pollution if the chemicals are not stored properly.

Which elements has the smallest first ionization energy?

Answers

Answer:

Cesium has smallest ionization energy.

Explanation:

Ionization energy is the energy that an atom at ground state must be absorb to release an electron to form a cation. for eg.

H ⇒ $H^(+) + e^(-)$

The unit of ionization energy is $(KJ)/(mol)$ .

The ionization energy is minimum for cesium & maximum for fluorine.

Ionization energy depends upon the radius of atom. cesium has smallest radius so it has low Ionization energy.

Therefore the cesium has smallest ionization energy.

In which space, outdoors or in your classroom, would it be easier to hear a musician? Explain

Answers

Answer:

It is easier to hear a musician in the classroom than outdoors

Explanation:

It is easier to hear a musician in the classroom due to the improved acoustics provided by the walls of the classroom whereby along with the direct sound of the musician, which is the lead source of the sounds, there is an increased number of indirect sound reaching the ear in the classroom than outdoors and due to precedence effect, all the sound appear to come from the musician

In music played outside, along side the direct sound from the musician, the indirect sound that reach the ear is echoed from maybe by only the ground while the majority of the sound from the music wanders away with the wind and in other directions as well as being absorbed such that speakers will be required to improve the sound of the music outdoors.
