Answer:
The number of protons in an atom is different than the atom's total mass.
Explanation:
Mendeleev had presented the first structured periodic table in 1869. But, in 1913, Henry Moseley developed the modern periodic table. The crucial difference between the two periodic tables is that Mendeleev's periodic table is generated on the basis of the atomic masses of chemical elements while the chemical element's atomic numbers were the main focus of Moseley's periodic table. There were just 56 chemical elements in Mendeleev's periodic table. On the other hand, 74 chemical elements are presented in Moseley's periodic table.

A funnel shaped cloud is called a funnel cloud.
If it touches the ground it is called a tornado.
Answer:
4.42 s
Explanation:
The frequency of the oscillation is given by the ratio between the number of complete oscillations and the time taken:
where for this glider, we have
N = 7.00
t = 31.0 s
Substituting, we find
Now we now that the period of oscillation is the reciprocal of the frequency:
So, substituting f = 0.226 Hz, we find:
