A). period is time
b). amplitude can be almost anything that waves . . . length, voltage, pressure, current etc.
But not hertz.
c). frequency ... "oftenness ... reciprocal time. the only item on this list that CAN be measured in Hertz.
d). wavelength ... length units
<span>The atomic number of
a neutral atom is equal to the number of protons and the number of electrons of
the atom. The atomic weight meanwhile is equal to the sum of the number of
protons and number of neutrons. In this case, the number of protons is equal to 26. The number of neutrons hence is 30. </span>
Answer:
7. d. England during the Age of Enlightenment
8. a. State governments do not usually act together
Explanation:
The Age of Enlightenment occurred in the 18th century and at this time England was a Constitutional monarchy with a monarch and parliament ruling the country with different powers.
The third and fourth methods of amending the Constitution will be much harder to use because state governments simply do not usually act together as they most times have ideological differences. The sheer number of states it would take to unite for these methods to be used makes this impractical.
<span>The solution for this
problem is:</span>
density = mass / volume <span>
7860 = 1 / ((4/3) pi r^3)
r^3 = 1 / (7860 * 4/3*pi)
r = (1 / (7860 * 4/3*pi))^(1/3)</span>
= 0.067 m <span>
Inertia = (2/5)mr^2</span>
= (2/5) x 1 x 0.067^2
= 0.0017956 kg-m^2 <span>
1/2.3 = 0.4348 rev/s
0.4348 x 2pi = 2.732 rad/s
Angular momentum = Inertia x rad/s
0.0017956 x 2.732 = 0.00490557 kg m^2/s</span>
