The mass of the sun is 1.99×1030kg and its distance to the Earth is 1.50×1011m. What is the gravitational force of the sun on the earth?

Answers

In order to calculate the gravitational force of the two bodies we use the formula which is expressed as:

F = GMm/R²

where G = 6.67 x 10^-11 in SI unit, M and m are the mass of the two bodies and R is the distance between them.

F = 6.67 x 10^-11 (1.99×10^30) (6×10^24) / (1.50×10^11)²
F = 3.53×10^22N

The gravitational force of attraction acting on the earth due to sun is $\boxed{3.539*{{10}^(22)}\,{\text{N}}}$ or $\boxed{3.54*{{10}^(22)}\,{\text{N}}}$ .

Further Explanation:

The Newton’s law of Gravitation states that the gravitational force of attraction acting between two bodies is directly proportional to the product of the mass of the two bodies and inversely proportional to the square of the distance between the two bodies.

Given:

The mass of the sun is $1.99*{10^(30)}\,{\text{kg}}$ .

The distance between the Earth and the sun is $1.50*{10^(11)}\,{\text{m}}$ .

Concept:

The gravitational force of attraction between the two bodies can be represented mathematically as:

$F=\frac{{G{M_1}{M_2}}}{{{r^2}}}$

Here, $F$ is the gravitational force of attraction, $G$ is the gravitational constant, ${M_1}$ is the mass of the first body, ${M_2}$ is the mass of the second body and $r$ is the distance between them.

Since the two bodies are Sun and the Earth so the masses of the two are considered.

The mass of the Earth is $6* {10^(24)}\,{\text{kg}}$ and the value of Gravitational constant is $6.67*{10^( - 11)}\,{{{\text{N}}\cdot{{\text{m}}^{\text{2}}}}\mathord{\left/{\vphantom{{{\text{N}}\cdot{{\text{m}}^{\text{2}}}}{{\text{k}}{{\text{g}}^{\text{2}}}}}}\right.\kern-\nulldelimiterspace} {{\text{k}}{{\text{g}}^{\text{2}}}}}$ .

Substitute $6.67*{10^( - 11)}\,{{{\text{N}}\cdot{{\text{m}}^{\text{2}}}}\mathord{\left/{\vphantom{{{\text{N}}\cdot{{\text{m}}^{\text{2}}}}{{\text{k}}{{\text{g}}^{\text{2}}}}}}\right.\kern-\nulldelimiterspace} {{\text{k}}{{\text{g}}^{\text{2}}}}}$ for $G$ , $1.99*{10^(30)}\,{\text{kg}}$ for ${M_1}$ , $6* {10^(24)}\,{\text{kg}}$ for ${M_2}$ and $1.50*{10^(11)}\,{\text{m}}$ for $r$ in above equation.

$\begin{aligned}F&=\frac{{\left({6.67*{{10}^(-11)}\,}\right)*\left({1.99*{{10}^(30)}\,{\text{kg}}}\right)*\left({6*{{10}^(24)}\,{\text{kg}}}\right)}}{{{{\left({1.50*{{10}^(11)}\,{\text{m}}}\right)}^2}}}\n&=\frac{{7.964*{{10}^(44)}}}{{2.25*{{10}^(22)}}}\n&=3.539*{10^(22)}\,{\text{N}}\n\end{aligned}$

Therefore, the gravitational force of attraction acting on the earth due to sun is $\boxed{3.539*{{10}^(22)}\,{\text{N}}}$ or $\boxed{3.54* {{10}^(22)}\,{\text{N}}}$ .

List the following items in order of decreasing speed, from greatest to least: (i) A wind-up toy car that moves 0.15 m in 2.5 s. (ii) A soccer ball that rolls 2.3 m in 0.55 s. (iii) A bicycle that travels 0.60 m in 0.075 s. (iv) A cat that runs 8.0 m in 2.0 s. Knight, Randall D., (Professor Emeritus). College Physics (p. 28). Pearson Education. Kindle Edition.

Answers

Answer:

(iii) > (ii) > (iv) > (i)

Explanation:

Part (i):

$\textrm{Speed of the wind-up toy} = \frac{\textrm{distance traveled}}{\textrm{Time taken}}\n\Rightarrow v_1=(0.15\ m)/(2.5\ s)\n\Rightarrow v_1 = 0.06\ m/s$

Part (ii):

$\textrm{Speed of the soccer ball} = \frac{\textrm{distance traveled}}{\textrm{Time taken}}\n\Rightarrow v_2=(2.3\ m)/(0.55\ s)\n\Rightarrow v_2 = 4.18\ m/s$

Part (iii):

$\textrm{Speed of the bicycle} = \frac{\textrm{distance traveled}}{\textrm{Time taken}}\n\Rightarrow v_3=(0.66\ m)/(0.075\ s)\n\Rightarrow v_3 = 8.8\ m/s$

Part (iv):

$\textrm{Speed of the cat} = \frac{\textrm{distance traveled}}{\textrm{Time taken}}\n\Rightarrow v_4=(8.0\ m)/(2.0\ s)\n\Rightarrow v_4 = 4.0\ m/s$

From the above calculations, we have

$v_3>v_2>v_4>v_1$

So, the speed in the parts mentioned arranged in decreasing order as follow:

(iii) > (ii) > (iv) > (i)
