Answer:
The strong forces oppose the electromagnetic force of repulsion between protons. Like ”glue” the strong force keeps the protons together to form the nucleus. The strong forces and electromagnetic forces both hold the atom together.

B. 8
Although it may seem that transition metals would have more than 8 valence electrons, they in fact do not.
Electric force is given by:
F = (kQ₁Q₂)/r²
where k is Coloumb's constant of value 9 x 10⁹, Q₁ and Q₂ are charges and r is the separation between them.
Let the charge of the nucleus be located at its center.
The separation of the proton is equal to:
Radius of nucleus + distance from surface
= 3 + 1.8
= 4.8 fm
Charge of Nucleus = 54e
Charge of proton = e
F = (9 x 10⁹ x 54 x 1.60 x 10⁻¹⁹ x 1.60 x 10⁻¹⁹)/(4.8 x 10⁻¹⁵)²
F = 540 N
Part 3)
The mass of the proton = 1.67 x 10⁻²⁹ kg
acceleration = 540/1.67 x 10⁻²⁹
= 3.20 x 10³¹ m/s²
<span>Greenhouse gases are so difficult to measure, because carbone dioxide, m</span>ethane, chlorofluorocarbons comes from multiple sources, some of which are relatively hard to measure.
For example, missions related to wetlands, deforestation, cattle, leakage from natural gas wells, storage facilities and distribution systems and because such leaks are highly variable and depend on factors such as well construction methods and maintenance systems for infrastructure.
