Chapter 13: Q. 1 (page 353)

Is the earth鈥檚 gravitational force on the sun larger than, smaller than, or equal to the sun鈥檚 gravitational force on the earth? Explain.

Short Answer

Expert verified

Earth's gravitational force on Sun is equal to the Sun's gravitational force on earth.

Step by step solution

01

Given Information

Gravitation force of earth on Sun and

Gravitational force of Sun on earth.

02

Explanation

Gravitational force is defined as F=G(m1脳m2)r2

Where m1 and m2 are the mass of two objects, r is distance between two objects and G is the constant .

Lets consider Sun and Earth system

From the figure the force

F1=G(msun脳mearth)r2

and Force F2 is

F2=G(msun脳mearth)r2

We can see F1 = F2 ,

so, Earth's gravitational force on Sun is equal to the Sun's gravitational force on earth.

Two Jupiter-size planets are released from rest 1.0 x 1011m apart. What are their speeds as they crash together?

You have been visiting a distant planet. Your measurements have determined that the planet鈥檚 mass is twice that of earth but the free-fall acceleration at the surface is only one-fourth as large.

a. What is the planet鈥檚 radius?

b. To get back to earth, you need to escape the planet. What minimum speed does your rocket need?

You are the science officer on a visit to a distant solar system. Prior to landing on a planet you measure its diameter to be 1.8脳107mand its rotation period to be role="math" localid="1648535932335" 22.3hours.You have previously determined that the planet orbits 2.2脳脳1011mfrom its star with a period of 402earthdays. Once on the surface you find that the free-fall acceleration is 12.2m/s2.What is the mass of (a) the planet and (b) the star?

In 2000, NASA placed a satellite in orbit around an asteroid. Consider a spherical asteroid with a mass of 1脳1016kgand a radius of 8.8km.

a. What is the speed of a satellite orbiting 5kmabove the surface?

b. What is the escape speed from the asteroid?

Large stars can explode as they finish burning their nuclear fuel, causing a supernova. The explosion blows away the outer layers of the star. According to Newton鈥檚 third law, the forces that
push the outer layers away have reaction forces that are inwardly directed on the core of the star. These forces compress the core and can cause the core to undergo a gravitational collapse. The
gravitational forces keep pulling all the matter together tighter and tighter, crushing atoms out of existence. Under these extreme conditions, a proton and an electron can be squeezed together to
form a neutron. If the collapse is halted when the neutrons all come into contact with each other, the result is an object called a neutron star, an entire star consisting of solid nuclear matter. Many neutron stars rotate about their axis with a period of 鈮� 1 s and, as they do so, send out a pulse of electromagnetic waves once a second. These stars were discovered in the 1960s and are called pulsars.
a. Consider a neutron star with a mass equal to the sun, a radius of 10 km, and a rotation period of 1.0 s. What is the speed of a point on the equator of the star?
