The more _________ an electron has, the further away it can be from the nucleus. mass
Monica [59]

Answer:

ectron's further from the nucleus are held more weakly by the nucleus, and thus can be removed by spending less energy. Hence we say they have higher energy. The Coulomb interaction energy between a nucleus of atomic number and an ele

The 8.1 N weight is in equilibrium under the influence of the three forces acting on it. The F force acts from above on the left
Luden [163]

Answer:

F=16.512\ N

\theta=74.38^{\circ}

Explanation:

Given:

Observe the schematic showing the angle direction and magnitude of the forces acting on the center of the mass.

Here we find that there are 3 forces acting on a point and we can build a relation among the forces and the angle between them using Lami's Theorem.

\frac{8.1}{sin\ (134-\theta)} =\frac{F}{sin\ (136)} =\frac{6.4}{sin\ (90+\theta)}

Now, from the extreme left and extreme right term:

\frac{8.1}{sin\ (134-\theta)} =\frac{6.4}{sin\ (90+\theta)}

\frac{8.1}{6.4} \times cos\ \theta=0.72\times cos\ \theta+0.7\times sin\ \theta

\theta=74.12^{\circ}

Now, for calculating force F:

\frac{F}{sin\ (136)} =\frac{6.4}{sin\ (74.12+\theta)}

F=16.25\ N
