Answer:
Explanation:
f =
T = 120 N
L = 3.00 m
(m/L) = 120 g/cm(100 cm/m / 1000 g/kg) = 12 kg/m
(wow that's massive for a "rope")
f = )
f = /6 = 0.527 Hz
This is a completely silly exercise unless this "rope" is in space somewhere as the weight of the rope (353 N on earth) far exceeds the tension applied.
A much more reasonable linear density would be 120 g/m resulting in a frequency of √1000/6 = 5.27 Hz on a rope that weighs only 3.5 N

Answer:
The underlined words are the answers
Part A
Moving from boron to carbon, the intensity of the bulb <u>Increases</u> because Z increases from <u>5</u> to <u>6</u> , The thickness of the frosting <u>stays the same </u> because the core electron configuration is the same for both atoms
Part B
Moving from boron to aluminum the intensity of the bulb <u>Increases</u> because Z increases from <u>5</u> to <u>13</u> . The thickness of the frosting also <u>increases</u> because Al has the core configuration of <u>Ne</u>, while B has the core configuration of <u>He</u>
Explanation:
Here Z denotes the atomic number
Ne denoted the element called Neon and its electronic configuration is
He denoted the element called Helium and its electronic configuration is
B denoted the element called Boron and its electronic configuration is
Looking at its electronic configuration we can see that the core is He
I,e
Al denoted the element called Aluminium and its electronic configuration is
Looking at its electronic configuration we can see that the core is Ne
I,e
