What is cosmic background radiation?

Answers

Answer 1

Answer:

Cosmic background radiation is the energy left over from the big bang and it's everywhere we look so if we consider ourselves the center, no matter which way we look we see this cosmic background radiation which is left over energy from the big bang.

Answer 2

Answer: Cosmic background radiation is electromagnetic radiation from the sky with no discernible source. The origin of this radiation depends on the region of the spectrum that is observed.

If We Start With 400 Atoms of a Radioactive Substance, How Many Would Remain After One Half-life ?

Answers

If it's half life, that means that half of the atoms have died out. Therefore, 200 atoms have died, so there are 200 atoms left (exactly one half of 400)

200, the half life of a radioactive substance is pretty simple to remember. It is literally cutting it in half, however, don't make the same mistake I did in this subject, the second half life does not reduce it to 0, it reduces it to 100. It just keeps half-lifing over and over again. For example: 400 atoms after one half life:200, after two: 100, after 3, 50, and so on.

What is the minimum resistance which can be made using five resistors each of 1/5

Answers

The minimum resistance to the flow of electrical current is achieved when
the resistors are connected in parallel, just as the minimum resistance to the
flow of vehicular traffic is achieved when several lanes are built in parallel.

When 5 equal resistors are connected in parallel, the net resistance of their
combination is just 1/5 of the value of each one.

So 5 equal resistors in parallel, each with a resistance of 1/5 ohm, have a
combined net resistance 0f 1/25 ohm.
