A negative charge i guess
Answer: Mendeleev arranged the elements in his periodic table in <em>order of increasing atomic mass.</em> In the modern periodic table, elements are arranged <em>in order of increasing atomic number</em>
The unstable nuclei undergo radioactive decay. The nucleus decay in form of emitting the radiations or changing into the different chemical element.
Thus, the nucleus decay takes place till the nuclei become stable.
Hence, given statement is false.
Answer:
glass if for a good view, but for absorbing heat concrete and brick is the best
Explanation:
wood is not a good idea bc it can cause fires from too much heat and it absorbs less heat but all of that depends on how good the material your using
A)
2revs in 0.08s
so in 1s thats 25revs
therefore thats <u>50π radians</u> in one second
b)
well, ω=2π/T
therefore ω=50π = 157.079rads^-1
and v=rω where r is in meters;
v=0.3x157.079
<u>v=47.123ms^-1</u>
c)
f=1/T
f=1/period for one rotation
1 rotation = 0.08/2 = 0.04
f=1/0.04
<u>f=25Hz</u>
