The answer is A. the moving charge induces a magnet field
.
Answer:
It will not change
Explanation:
The period of oscillation of a mass-spring system is given by

where
T is the period
m is the mass hanging on the spring
k is the spring constant
As we see from the formula, the period of oscillation does not depend on the amplitude of the motion: therefore, if we change the amplitude, the time for one oscillation will not change.
Groups
Same number of valence electrons
Li, Na, K
Explanation:
A.
If the periodic table is not color coded, the groups of elements gives the arrangement of atoms with the same chemical properties.
All elements that are in the same group have the same chemical properties.
Periodic table groups are also called family. They are the vertical columns on the periodic table.
B.
Elements that same number of electrons in outermost shell have the same chemical properties.
The outermost shell is called the valence shell of an atom.
They are the shell containing the most loosely held electrons. Group 1 has just one electron in their outermost shell.
C.
Li Na k group 1
F Cl Br group 7
