The correct answer is <span>D) centrifuge the mixture because the substance with the highter density will be pulled to the bottom
When things spin around, like a centrifuge, the centripetal force draws things towards the middle. If you make it a bit like a spiral and put it sideways, then the denser thing will go to the bottom while the less dense ones will remain on the outside. </span>
The answer is A. The vibration caused by the waves through the air eventually weaken, which is why sound diminishes easily over distance.
Answer : The volume of the resulting solution will be 0.4999 L.
Explanation : As the two molar concentration of the
solution are given and one of the volume concentration needs to be found.
So, according to the formula :-
And here if we consider
as 0.1718 L moles and
as 0.3556 moles then we need to find
as
is given as 0.1222 moles.
Hence on solving the formula we get,
= (0.1718 X 0.3556) / 0.1222 = 0.4999 L
The <u>option which correctly compares beta decay and gamma decay</u> is Beta-decay releases a particle, while gamma decay only reduces the energy level. Beta-decay is a form of nuclear fission, but gamma decay is not.
Beta decay is a form of radioactivity in which an electron is released. The electron could be positively charged(positron) or negatively charged.
Also, beta decay also occurs when there is nuclear fission of a substance in which a larger atom breaksdown into a smaller atom and releases energy.
Gamma decay is a form of radioactivity in which photons are released without the release of a particle from the atom.
Since a photon is released, only the energy level of the atom reduces and is thus not a form of nuclear fission
So, the <u>option which correctly compares beta decay and gamma decay</u> is Beta-decay releases a particle, while gamma decay only reduces the energy level. Beta-decay is a form of nuclear fission, but gamma decay is not.

Explanation: <u><em>
The fertilized egg zygote divides repeatedly as it moves down the fallopian tube to the uterus. First, the zygote becomes a solid ball of cells. ... Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes.</em></u></h3><h3><u><em /></u></h3>
