Kepler's Third Law states that the square of the time period of orbit is directly proportional to the cuber of the semi-major axis of that respective orbit. (the semi-major axis for a circular orbit is of course the radius) Mathematically this can be represented as: T2 / r3 = k where k is a constant. The value k is related to physical ...

Bookmarks. P is directly proportional to s means => p = x times s (as s increases p increases, x is constant) P is inversely proportional to r means => p = y divided by r (as r increases p decreases, y is constant) So we can say. p= z times s divided by r (z is a constant different from x and y) When p=1, s =2 and r=0,5.

WebMar 17, 2024 · Step-by-step explanation: Given that M is directly proportional to r² then the equation relating them is. M = kr² ← k is the constant of proportionality. To find k use the condition when r = 2 , M = 14. k = = =. M = r² ← equation of proportion. When M = 224, then. 224 = r² ← multiply both sides by 2. 7r² = 448 ( divide both sides by 7 )
