White dwarfs: properties - Remaining cores of dead, low mass stars Electron degeneracy pressure supports them against gravity Slowly fade with time Sirius and its hot WD companion White dwarfs with same mass as Sun are about same size as Earth; slowly cooling Typical density 10^6 gram / cubic cm Higher mass white dwarfs are smaller Cannot be more massive than 1.4MSun, the Chandrasekhar limit WDs in binaries: nova, supernova Type I - Mass falls toward white dwarf from binary companion ...

1. What two properties of a planet affect the gravity we feel on its surface? A: radius and distance from the Sun B: radius and temperature C: mass and distance from the Sun D: mass and radius E: mass and temperature - D 2. Two planets have the same radius. If Planet A is 5 times more massive than Planet B, how does gravity differ on the surfaces of the two planets? A: gravity is 5 times stronger on Planet B B: gravity is 5 times stronger on Planet A C: gravity is 25 times stronger on ...

The force of gravity by the Sun keeps the planet in orbit around it, but how do the planets affect the sun? - correct answer They exert an equally strong pull on the sun, causing it move slightly Newton's First Law - correct answer An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. ex: if the sun suddenly disappeared, the Earth would continue in the direction that it was traveling ...

How high are you jumping at twice Earth's mass compared to Earth's mass? - Half as high Since the jump height is half as high what does that tell us about gravity? - Twice as much. (More gravity = lower jump height) Now we can change the mass to 0.5M. If we do, how much higher are you jumping than at one Earth mass? - Twice as high Now we can change the mass to 0.25M. If we do, how much higher are you jumping? - Four times as high As the mass of the planet increases, the jump height ___...

What two properties of a planet affect the gravity we feel on its surface? - Answer- Mass and radius Two planets have the same radius. If Planet A is 5 times more mass than Planet B, how does gravity differ on the surfaces of the two planets? - Answer- Gravity is 5 times stronger on planet A Say that there were a planet X in our Solar System with a mass 1/4 the mass of Earth and a radius 1/2 the radius of Earth. How will the gravity on its surface compare to the surface gravity of Earth? -...

Gleim Private Pilot FAA Knowledge Test Guide Gleim Private Pilot FAA Knowledge Test Guide What is one purpose of wing flaps? To enable the pilot to make steeper approaches to a landing without increasing the airspeed. One of the main functions of flaps during approach and landing is to: Increase the angle of descent without increasing the airspeed. What is the purpose of the rudder on an airplane? To control yaw. Which is not a primary flight control surface? A. Flaps B. Stabilat...
