The complete sentence is the following:
<span>" As the size of the nucleus increases, more NEUTRONS are needed to maintain the attractive force. "
In fact, as the size of the nucleus increases and the number of protons increases, the repulsive electrostatic forces between them increase as well (because the protons have the same electric charge, so they repel each other). In order to hold them together, it is necessary to have more neutrons in the nucleus. In fact, the strong nuclear force acts between protons and neutrons holding them together, like a "glue", and preventing the nucleus from breaking apart due to the repulsive electrostatic force of the protons.</span>
Answer:
Prominences
Explanation:
Their arched shapes show that they are formed of ionized gas trapped in the magnetic field. You see prominences in filtergrams as dark filaments silhouetted against the bright chromosphere.
Answer:
The height of the water column = 1.62405
× 10⁻¹ m
Explanation:
The air cavity in the Coke bottle = 0.220 m deep
The fundamental (frequency) it plays when water is added to shorten the column and it is blown across the top, f = 528 Hz
The given speed of sound in air, v = 343 m/s
We note that the air cavity in the coke bottle is equivalent to a tube closed at one end
The fundamental frequency for a tube closed at one end, 'f', is given as follows;
f = v/(4·L) = v/λ
Where;
L = The height of the water column
λ = The wavelength of the wave
∴ 4·L = v/f = (343 m/s)/(528 Hz) = 0.6496
m
∴ L = 0.6496
m/4 = 0.162405
m
The height of the water column = 1.62405
× 10⁻¹ m.
