Answer from: shelby8385

$3.524(10)^{22}N$

Explanation:

According to Newton's law of Gravitation, the force exerted between two bodies of masses and and separated by a distance is equal to the product of their masses and inversely proportional to the square of the distance:

$F=G\frac{(m1)(m2)}{r^2}$ (1)

Where:

is the Gravitational Constant and its value is $6.674(10)^{-11}\frac{m^{3}}{kgs^{2}}$

$m1=1.99(10)^{30}kg$ is the mass of the Sun

$m2=5.972(10)^{24}kg$ is the mass of the Earth

$r=1.50(10)^{11}m$ is the distance between the Sun and the Earth

Substituting the values in (1):

$F=6.674(10)^{-11}\frac{m^{3}}{kgs^{2}}\frac{(1.99(10)^{30}kg)(5.972(10)^{24}kg)}{(1.50(10)^{11}m)^2}$ (2)

Finally:

$F=3.524(10)^{22}N$ This is the gravitational force acting on the earth due to the sun

Answer from: lakesha04begaye

The magnitude of the gravitational force : 3.48.10²² N

Further explanation

Gravity is a force that arises because of the attraction between objects with mass.

The magnitude of this attraction is proportional to the mass of the object.

The greater the mass of the object, the greater the gravitational force

Relationships can both be stated in

Newton's Gravity Law:

$\rm F=G.\dfrac{m_1.m_2}{r^2}$

with F = gravitational force,

G = gravitational constant,

m1, m2 = mass of object,

r = distance between two objects.

From the available data:

m earth = 5.98.10²⁴ kg

m sun = 1.99.10³⁰ kg

r = 150 million km = 15.10⁷ km = 15.10¹⁰ m

G = 6.67.10⁻¹¹N.m² / kg²

We put in the formula:

$\rm F=6.67.10^{-11}.\dfrac{5.98.10^{24}.1.99.10^{30}}{(15.10^{10})^2}\\\\F=3.48.10^{22}\:N$

So The earth exerts 3.48.10²² N of force on the sun, exactly the same amount of force the sun exerts on the earth

Answer from: Quest

An atom (ours, not carroll's) consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6 nm. * if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
