QUESTION 3Likewise, the emitted power per unit area from the planet (EP) can be calculated by the Stefen-Boltzman law with EP-OT4. The parameter T is the equilibrium temperature of the planet, which is close to the actual temperatureof the planet. In addition, scientists measured the global albedo (A) of the planet, which is the ratio between the reflected solar power and the total solar power. The global albedo of the planet A=0.5. With the albedo A, theabsorbed solar power per unit area by the planet (AP) can be expressed by AP-Pp(1-A), where Pp is the solar power per unit area at the distance of the planet (see Question 2). Note: AP and EP are powers per unit area. Theplanet absorbs the solar power through an imaginary disc that has a radius equal to the radius of the planet (r). The area of the imaginary disc for the absorbed solar power (SAP) can be expressed as SAP = Tr². Therefore, thetotal absorbed solar power (APtotal) by the planet can be calculated by APtotal-AP x SAP-AP T²= Pp (1-A) r². At the same time, the planet emits power from its whole sphere. The surface area of a spherical planet (SEP) canbe calculated by SEP=4Tr², and hence the total emitted power (EP total) by the planet can be expressed as EP total-EPXSEP-EPX4T₁²=OT44πr². If we assume a balance between the total absorbed solar power and the totalemitted power for the planet, we have APtotal = EPtotal- Based on the balance AP total = EP total and the estimated Pp in Question 2, please estimate the equilibrium temperature of the planet (T).0T~ 343KelvinsOT-443KelvinsOT-543Kelvins0 T~ 643Kelvins QUESTION 1Estimate The Temperature For A Planet In Other Solar System (Questions 1-3)Let us assume scientists just discovered a planet orbiting a star in an extra-solar system.

Read this main idea: The sun is the center of our solar system. Choose three details that go with the main idea. The sun's gravity holds the planets in place. It provides them with heat and light. The largest stars, called supergiants, are 1,500 times bigger than our sun. It takes Earth 365 days to orbit the sun. Jupiter takes 12 years! Our sun is not the largest or hottest star. It is a medium sized yellow star. Radio telescopes use radio waves to show stars in great detail. Astronomers long ago and today use star charts to map star locations. All of the planets in our solar system revolve around one star-our sun. Stars can be blue, white, yellow, or red. Blue stars are the hottest. A reflector telescope bounces star light through mirrors.

4) Science fiction movies often portray asteroid belts as crowded, dense regions that require spaceships to maneuver quickly to get through them. In this problem, we will calculate the fraction of volume in an asteroid belt that is actually occupied by asteroids. a) If there are 300,000 large asteroids between 2 and 3 AU from the Sun, and each asteroid is assumed to be spherical with a radius of 100 km, determine the total volume occupied by asteroids in this region. Recall that the volume of a sphere is given by the equation V = 4TR³ /3. b) Let's assume the region in which these asteroids orbit is an annulus with an inner radius of 2 AU, an outer radius of 3 AU, and a thickness of 2Ro. Determine the volume of this region. Recall that the area of a circle is given by the equation A = TR². Here are two conversions that you'll need: 1 AU = 1.496 × 108 km and 1 Ro = 6.955 × 105 km. c) What is the ratio of the volume occupied by asteroids to the volume of the asteroid belt (i.e., the…

How many orders of magnitude do you need to grow in spatial scale (size) to form a planet? Let's take the extreme ends of this scale, from a dust particle of radius a = 10-6m to the gas giant Jupiter (you can round up its radius to the nearest ten to keep it simple). What else has this difference in order of magnitude? Maybe pick something that's not a length scale. Be creative!
