Why does the solar system consist of small planets orbiting close to sun and larger on more distant
ahrayia [7]

Answer:

The inner planets are smaller and rockier

Explanation:

Astronomers divide the planets into two groups in Solar system,  the  inner planets and outer planets. The inner planets are smaller and rockier and it is closer to the sun.  The outer planets are larger , further far away and made of gas

The inner planets are Mercury, Venus , Earth and Mars.  The outer planets Jupiter , Saturn , Uranus and Neptune comes after an  asteroid belt. In some other planetary systems the gas are close to the sun.

particles in a disk of gas and dust will form Planets.  If they orbit the star they are colliding and sticking.  The stars wind blows away their gases . So the nearest planets to starts are rockier.

Elanso [62]

Answer:

8.13secs

Explanation:

From the question weal are given

Height H =324m

Required

time it takes to drop t

Using the equation of motion

H = ut + 1/2gt²

Substitute the given values

324 = 0(t)+1/2(9.8)t²

324 = 1/2(9.8)t²

324 = 4.9t²

t² =324/4.9

t² = 66.12

t = √66.12

t = 8.13secs

Hence the time taken to drop is 8.13secs

Line segment gj is a diameter of circle l. angle k measures (4x 6)°. circle l is inscribed with triangle g j k. line segment g j
choli [55]

The value of x in the given right triangle in a semicircle is determined as 21.

<h3>What is the measure of a triangle in a semicircle?</h3>

The triangle in a semicircle is always a right angle triangle.

From the figure shown, we can say that the triangle  G J K is right triangle and m<K = 90degrees.

Given that m<K = 4x + 6, we will can use the following equation to find the value of x as shown:

4x + 6 = 90

4x = 90 - 6

4x = 84

x = 21

Thus, the value of x in the given right triangle in a semicircle is determined as 21.
