The required orbital velocity is a little more than 17,000 mph (about 27,400 kph).
Answer:
You also know about the mass of that sample, if you know the moles
(First option)
Explanation:
Moles = Mass / Molar mass
Moles . Molar mass = Mass
For example, I have 4 moles of H₂O
Molar mass H₂O = 18 g/m
4 m . 18 g/m = 72 g
If I have 4 moles of H₂O, I also have 72 grams of water too.
All they do is simply expand when you inhale and contract when you exhale.
Answer:
mental
Explanation:
the element is vanadium, it is a Transition metal
<span>The balance equation will be
234/91 Pa --> 234/92 U + </span>a beta particle
An example of it is potassium-40 nucleus. A beta particle has a high-energy and high-speed electron in the radioactive decay. These particles ranges <span> from 0 MeV to 4 MeV. It carry one charge only and it is positively charge, it is called positron.</span>
