Answer:
Work
Explanation:
Work is defined as the ability to use energy in one second and its SI unit is same as energy that is joule.
Work refers to the energy utilized to displace an object over a distance by an external force in one direction and in given time period which can be one second as well.
Hence, the correct answer is "work".
Remark
The given thing on the right is a positron. The mass for these subatomic particles is considered to be 0. It's atomic number is 1 which means it is a blood relative of a proton.
So essentially what happens is that X is one space to the left on the periodic table. But let's solve this a little bit more formally.
Solution

y stays the same at 147. It is z that changes.
65 = z + 1 Subtract 1 from both sides.
64 = z
So the chemical with 64 as its position on the periodic table is
Gadolinium and the answer is C
Answer:
this isnt even a question...
Explanation: what the heck
Answer:
Ideal Gas
The ideal gas is extremely small and the mass is almost zero and no volume Ideal gas is also considered as a point mass.
Real Gas
The molecules of real gas occupy space though they are small particles and also have volume.
