What force causes weight? How is weight affected as an object moves farther away from the center of the earth?

stich3 [128]

Gravity affects weight of an object

Its weight reduces as it moves away from the center as gravity is strongest near the core and reduces as you move away

(a) What is the minimum speed, relative to the Sun, necessary for a spacecraft to escape the solar system if it starts at the Ea

mixer [17]

Let the minimum speed required be : $V$

Now, to escape solar system means to escape the gravitational pull of the Sun.

The escape velocity is given as: $v=\sqrt{\frac{2 G M}{r}}$

$M &=\text { mass of } \text { sun }=1.9 \times 10^{30} \mathrm{~kg} \\ \\ \\r=\text { distance b/w Earthis orbit }$

$$r=$ distance b/w Earthis orbit of sun.$

$=1.5 \times 10^{11} \mathrm{~m}$

$$$ $G=$ gravitational constant.$

Thus,

$\quad v=\sqrt{\frac{2 \times 6.67 \times 10^{-11} \times 1.9 \times 10^{30}}{1.5 \times 10^{11}}}$

Hence,

$$\quad v=4.2 \times 10^4 \mathrm{~m} / \mathrm{s}$.$

<h3>Why is it called a solar system?</h3>

There are numerous planetary systems like our own within the universe, with planets orbiting a host star. Our planetary system is named the "solar system" since our Sun is named Sol, after the Latin word for Sun, "solis," and anything related to the Sun we call "solar."

Our solar system comprise of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Defaces, Jupiter, Saturn, Uranus, and Neptune; predominate planets such as Pluto; handfuls of moons; and millions of space rocks, comets, and meteoroids.

Consider the following neutral electron configurations in which n has a constant value. Which configuration would belong to the

grandymaker [24]

Answer:

he configuration with the highest electronic affinity is 2s2 2p5

Explanation:

Electronic affinity is the variation of energy when we add an electron to a neutral atom to form an ion

When an electron is added, it must occupy a space is the sub-level of the atom, giving more stability when it approaches the configuration of a complete shell with eight electrons (noble gas), so the affinity must increase when moving in a period Group VIII noble gases)

Let's examine the given settings

In this case, when adding an electron, 2s2 is very far from a complete level configuration, so its affinity must be small.

2s2 2p2 when adding an electro the one has a little more affinity, but is still a long way from a full shell, it would be missing 3 electrons

2s2 2sp5 this is the atom with the highest electronic affinity, since i = that when adding an electron the ion has the configuration of a noble gas. This is the most stable on the list

2s2 2p6 already has a full shell making it very difficult to insert an electron into this atom.

In summary, the configuration with the highest electronic affinity is 2s2 2p5
