a. The gravitational force of the sun on the earth is $3.54\times 10^{22}$ Newton.

b. The gravitational force of the moon on the earth is $2.0 \times 10^{20}$ Newton.

c. The percent of the moon's force to that of the sun's force is 0.57%

Given the following data:

Mass of sun = $1.99 \times 10^{30}$ kgDistance = $1.55 \times 10^{11}$ meter.Mass of moon = $7.36 \times 10^{22}$ kgDistance = $3.84 \times 10^{8}$ meter.Mass of earth = $6.0\times 10^{24}$ kgGravitational constant = $6.67\times 10^{11}$

a. To find the gravitational force of the sun on the earth:

Mathematically, Newton's Law of Universal Gravitation is given by the formula:

$F = G\frac{M_1M_2}{r^2}$

Where:

F is the gravitational force.g is the gravitational constant.M is the masses of object. r is the distance between centers of the masses.

Substituting the given parameters into the formula, we have;

$F = 6.67\times 10^{-11} \frac{(1.99 \times 10^{30} \times 6.0 \times 10^{24})}{(1.5 \times 10^{11})^2}\\\\F = 6.67\times 10^{-11} \frac{(1.194 \times 10^{55}) }{2.25 \times 10^{22}}\\\\F = \frac{7.96 \times 10^{44} }{2.25 \times 10^{22}}$

F = $3.54\times 10^{22}$ Newton.

b. To find the gravitational force of the moon on the earth:

$F = 6.67\times 10^{-11} \frac{(7.36 \times 10^{22} \times 6.0 \times 10^{24})}{(3.84 \times 10^{8})^2}\\\\F = 6.67\times 10^{-11} \frac{(4.42 \times 10^{47}) }{1.47 \times 10^{17}}\\\\F = \frac{2.95 \times 10^{37} }{1.47 \times 10^{17}}$

F = $2.0 \times 10^{20}$ Newton.

c. To find what percent is the moon's force to that of the sun's force:

$Percent = \frac{2.0 \times 10^{20}}{3.54\times 10^{22}} \times 100$

Percent = 0.57%

Answer from: nscarlisleh13

PART A:

As we know that gravitational force is given by

$F=\frac{GMm}{r^2}$

Here we know that

G = Gravitational constant.

M = mass of the sun = $1.99 \times 10^{30} kg$

m= mass of the Earth = $6 \times 10^{24} kg$

r = distance between them = $1.5 \times 10^{11}$

Sonow we have

$F=\frac{(6.67\times 10^{−11})(1.99\times 10^{30})(6\times 10^{24})}{ (1.5\times 10^{11})²}$

$F=3.53 \times 10^{22}N$

Part B)

As we know that gravitational force is given by

$F=\frac{GMm}{r^2}$

Here we know that

G = Gravitational constant.

M = mass of the moon = $7.36 \times 10^{22} kg$

m= mass of the Earth = $6 \times 10^{24} kg$

r = distance between them = $3.84 \times 10^{8}$

Sonow we have

$F=\frac{(6.67\times 10^{−11})(7.36\times 10^{22})(6\times 10^{24})}{ (3.84\times 10^{8})²}$

$F=1.99 \times 10^{20}N$

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
