Two planets X and Y travel counterclockwise in circular orbits about a star, as seen in the figure.
sergeinik [125]

Planet Y has rotated by 135.5° through during this time.

To find the answer, we need to know about the relation between angle and radius of orbit.

<h3>What's the expression of angle in terms of radius?</h3>
  • Angle= arc/radius
  • As arc = orbital velocity × time,

            angle= (orbital velocity × time)/radius

  • Orbital velocity= √(GM/radius), G= gravitational constant and M = mass of sun
  • So, angle = (√(GM)× time)/radius^3/2
<h3>What's is the angle rotated by planet Y after 5 years, if ratio of the radius of orbit of planet X and Y is 4:3 and planet X is rotated by 88°?</h3>
  • Let Ф₁= angle rotated by planet Y, Ф₂= angle rotated by planet X
  • As time = 5 years ( a constant)
  • Ф₁/Ф₂= (radius of planet X / radius of planet Y)^(3/2)
  • Ф₁= (radius of planet X / radius of planet Y)^(3/2) × Ф₂

   = (4/3)^(3/2) × 88°

   = 135.5°

Thus, we can conclude that Planet Y has rotated by 135.5° through during this time.

Measure the distance from the drop point in Brazil to the drop point in Angola. Use that number in your calculation. Given that
klemol [59]

To develop this point we will start by finding the approximate coordinates of the points that were connected at the time of the Pangaea between Brazil and Angola. These coordinates are presented below.

1 . Brazil - Latitude: 18 0 07’ 55.56” S Longitude: 39 0 35’ 14.50” W 2.

Angola - Latitude: 9 0 08’ 50.02” S Longitude: 13 0 02’ 32.11” E

Using a tool for calculating distances between these two points we will notice that its distance is 576,155,570.12 cm

Applying the equation given in the statement we will have to,

v = \frac{x}{t} \rightarrow v = Velocity, x = Distance, t = Time

200,000,000 years have passed and the movement was previously found, so the speed of travel is,

v = \frac{576,155,570.12cm}{200.000.000 years}

v = 2.88 cm/year

Therefore the velocity is 2.88 cm per year.
