What is the meaning of G4 P3 A1 A1?
Obstetric history: G4, P3, A1 or gravida 4, para 3, abortus 1. When one or more of the numbers is 0, the preferred form is to write out the terms: gravida 2, para 0, abortus 2. G: gravida (number of pregnancies) P: para (number of births of viable offspring) A or Ab: abortus (abortions) nulligravida gravida 0: no pregnancies
What is Kepler's third law P2 A3?
4) Kepler's third law, p2 = a3, means that. A) the period of a planet does not depend on its mass. B) all orbits with the same semimajor axis have the same period. C) planets that are farther from the Sun move at slower average speeds than nearer planets. Click to see full answer.
What is a g5p2l3?
So if she's had 5 pregnancies and 3 living kids including the twins, she's a G5P2L3. I'll look for some sources on that one, because it's always a big argument between nurses where I work.
What does P 2 a 3 stand for?
The equation for Kepler's Third Law is P² = a³, so the period of a planet's orbit (P) squared is equal to the size semi-major axis of the orbit (a) cubed when it is expressed in astronomical units.
What is the ratio of P2 a3 for Mars?
Mars' orbital period (1.88 Earth years) squared, or P2, is 1.882 = 3.53, and according to the equation for Kepler's third law, this equals the cube of its semimajor axis, or a3. So what number must be cubed to give 3.53? The answer is 1.52 (since 1.52×1.52×1.52=3.53).
What is Kepler's 3rd law simplified?
Kepler's Third Law: the squares of the orbital periods of the planets are directly proportional to the cubes of the semi-major axes of their orbits. Kepler's Third Law implies that the period for a planet to orbit the Sun increases rapidly with the radius of its orbit.
What is G in Kepler's third law?
The Gaussian constant, k, is defined in terms of the Earth's orbit around the Sun. The Newtonian constant, G, is defined in terms of the force between two two masses separated by some fixed distance.
How do you use P 2 a 3?
Kepler's 3rd Law: P2 = a. 3 It means that if you know the period of a planet's orbit (P = how long it takes the planet to go around the Sun), then you can determine that planet's distance from the Sun (a = the semimajor axis of the planet's orbit).
How long is a year on Mars?
687 daysMars / Orbital periodThe Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days - one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days - or one Mars year.
When written as P2 a3 Kepler's third law with P in years and a in AU is applicable to?
The third law p2=a3 relates period to semi major axis distance. In fact the third law as stated only works if the period is in years and the semi-major axis is in Astronomical Units (AU). These laws apply to all planets irrespective of mass.
What does R3 mean in astronomy?
For our solar system and planets around stars with the same mass as our sun, that simply states that R3 = T2, where R is a planet's distance from the sun in Astronomical Units (AU) and T is the planet's orbital period in years.

What is v2 GM R?
Formula: v2 = GM(2/r - 1/a) where G = 6.67 x 10-11 N m2 / kg2, M is the mass of the planet (or object to be orbited), r is the radial distance of the orbiting object from the center of the planet (or object to be orbited) at a given moment. a is the semi-major axis of the elliptical orbit.
What is a value of G?
Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2.
What is G in Kepler's?
where Eorbit is the constant energy, r is the instantaneous distance of the planet from the sun, v is the instantaneous speed, G is the universal gravitational constant, M is the sun mass, and m is the planet mass.
Guide to Obstetrical Words
Obstetrics deals with pregnancy, childbirth, and the post-natal period. Familiarity with obstetrics terminology is necessary to understand and practice obstetrics and gynecology (OB-GYN). Some words are heavily coded and may be confusing at times.
