sammy [17]

Answer:

Fusion rates and star evolution increase rapidly because of the conversion of hydrogen molecules to helium.

Explanation:

At the early stage of a star mass, hydrogen atoms are produced. After a few billion years, these hydrogen atoms formed at the core of the star mass begin to fuse on the external side of the core. Hydrogen atoms get rapidly fused, resulting to a contraction of the star core, and as more hydrogen atoms get fused, helium atoms are formed.

This action results into rapid into a rapid and violent burning action of hydrogen atoms around the core.

An electron (charge −e=−1.60×10−19C−e=−1.60×10−19C) is at rest at a distance 1.00×10−10 m 1.00×10−10m from the center of a nucle
shtirl [24]

Answer:

-9.45\times10^{-16} \text{ J}

Explanation:

According to Coulomb's law, the force of attraction between two point charges, q_1 and q_2, separated by a distance d is given by

F = k\dfrac{q_1q_2}{d^2}

k is a constant with a value of 9\times10^9\text{ F/m}.

When we substitute the values from the question,

F = (9\times10^9\text{ F/m})\dfrac{(-1.60\times10^{-19} \text{ C})\times(+1.31\times10^{-17}\text{ C})}{(1.00\times10^{-10}\text{ m})^2} = -1.89\times10^{-6} \text{ N}

This value is negative because it is in a direction towards the positive charge.

The work done in moving the electron from the nucleus is

W = F\times r

W = (-1.89\times 10^{-6} \text{ N})\times(5.00\times10^{-10}\text{ m}) = -9.45\times10^{-16} \text{ J}

This is negative because work is done on the electron, not by it.
