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 $\boxed{3.54* {{10}^(22)}\,{\text{N}}}$ .

A hailstone traveling with a velocity of 43 meters per second comes to a virtual stop at 0.28 seconds after hitting water.what is the magnitude of it acceleration in water

Answers

Answer:

For Plato users the best answer will be 1.5 x 10^2 meters/second^2

Explanation:

as for the reasoning of the other answer, they didn't include scientific notation.

Magnitude of acceleration = (change in speed) / (time for the change)

Change in speed = (final speed) minus (initial speed)

= ( zero ) minus (43 m/s) = - 43 m/s .

Magnitude of acceleration = ( - 43 m/s ) / (0.28 sec) = - 153.6 m/s²

Dark spots on the photosphere are known asA. the corona.
B. the chromosphere.
C. sunspots.
D. solar wind.

Answers

The dark spots that are found on the photosphere are called sunspots. These are a temporary phenomena and are areas of different temperature compared to the surroundings. Sunspots are at a lower temperature compared to the surrpundings and they are created due to magnetic field flux. They can stay on from a few days to a few months and eventually decay.

Answers

The best description of a grizzly bear’s habitat is:

D. the physical area where the bear lives

A habitat is the natural surrounding or place where an organism lives, grows and competes with other organisms for resources. It is a physical area.

There are three major types of habitat which includes:

Freshwater habitat: This refers to the area of water where animals live. Examples of animals that live in a freshwater habitat includes: sea turtle, fishes, etc. Examples of freshwater habitat include:

Rivers
Lakes
Pond, etc

Marine water habitat: This is where a group of organisms live. Examples include:

Oceans
Seas, etc.

Coastal habitat: This is an intersection between the land and sea habitats.

A grizzly bear is a subspecies of brown bear and is resident in the northern plains of America and their habitat is a physical location where they live.

Therefore, the correct answer is option D
