What other factor affected the gravitational force between the two objects in this simulation?

1 answer:

neonofarm [45]3 years ago

7 0

Answer:

The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases

Answer: (x - 4)² + (y - 7)² = 9

<u>Explanation:</u>

The equation of a circle is: (x - h)² + (y - k)² = r² where

(h, k) is the center
r is the radius

Given: (h, k) = (4, 7)

Find the intersection of the given equation and the perpendicular passing through (4, 7).

3x - 4y = -1

-4y = -3x - 1

$y=\dfrac{3}{4}x-1$

$m=\dfrac{3}{4}$ --> $m_{\perp}=-\dfrac{4}{3}$

$y-y_1=m_{\perp}(x-x_1)\\\\y-7=-\dfrac{4}{3}(x-4)\\\\\\y=-\dfrac{4}{3}x+\dfrac{16}{3}+7\\\\\\y=-\dfrac{4}{3}x+\dfrac{37}{3}$

Use substitution to find the point of intersection:

$x=\dfrac{29}{5}=5.8,\qquad y=\dfrac{23}{5}=4.6$

Use the distance formula to find the distance from (4, 7) to (5.8, 4.6) = radius

$r=\sqrt{(5.8-4)^2+(4.6-7)^2}\\\\r=\sqrt{3.24+5.76}\\\\r=\sqrt9\\\\r=3$

Input h = 4, k = 7, and r = 3 into the circle equation:

(x - 4)² + (y - 7)² = 3²

(x - 4)² + (y - 7)² = 9

On earth, the solar constant is approximately I = 1367 W/m2 . This corresponds to the power per unit area that a detector at the

d1i1m1o1n [39]

Answer:

Explanation:

for earth -sun system

E = σ T⁴ , E is radiation emitted by sun at temperature T

E = 4π R₁² x solar constant on earth , R₁ is distance between earth and sun.

for marsh -sun system

E = σ T⁴ , E is radiation emitted by sun at temperature T

E = 4π R₂² x solar constant on Mars , R₂ is distance between earth and sun.

from two equation ,

4π R₂² x solar constant on Mars = 4π R₁² x solar constant on earth

solar constant on Mars = (R₁ / R₂ )² x solar constant on earth
