Based on what you've learn on the impact of the Earth-Sun distance on the seasons, what can you say about the the cause of the seasons? (Give ALL correct answers, i.e., B, AC, BCD...)A) Earth's axis is tilted an an angle of 23.5 degrees compared to a line perpendicular (straight up and down) to its orbit, which is the main cause for the seasons.B) Earth's speed varies in its orbit around the Sun, giving us summer when Earth is moving fastest and winter when Earth is moving slowest.C) The Earth-Sun distance play a major role in creating seasons on Earth.D) The tilt of Earth's axis causes the Northern Hemisphere to be closer to the Sun than the southern hemisphere in summer, and vice versa in winter. E) The tilt of Earth's axis causes different portions of the Earth to receive more or less direct sunlight at different times of year.F) Earth's Northern Hemisphere is always tilted away from the Sun at an angle of 23.5 degrees.G) Earth's Northern Hemisphere is always tilted toward the Sun…
Mars is 1.5 times as far away from the Sun as Earth. Earth’s axis is tilted at 23.5o compared to the ecliptic. The axis of Mars is tilted at 25o compared to the ecliptic. The atmosphere on Earth is 100 times as thick as the atmosphere on Mars. Which of the following statements is true?
1.)Mars is so cold that the water there is ice, while Earth does not have any ice
2.)When it is summer in Earth’s northern hemisphere, it is winter on Mars’ southern hemisphere
3.) Earth has seasons, Mars does not
4.) All of the water on Mars is frozen, while Earth has water in solid, liquid and gas form
The Mars Robotic Lander for which we are making these calculations is designed to return samples of rock from Mars after a long time of collecting samples, exploring the area around the landing site, and making chemical analyses of rocks and dust in the landing area. One synodic period is required for Earth to be in the same place relative to mars as when it landed.
Calculate the synodic period (in years) using the following formula:
1/Psyn = (1/PEarth) - (1/PMars)
where PEarth is the sidereal period of the Earth (1 year) and PMars is the sidereal period of Mars.
If 3/4 of a Martian year was spent collecting samples and exploring the terrain around the landing site, calculate how long the Mars Robotic Lander expedition took!

Thank you!!arrow_forwardIf the sun suddenly ceased to shine, how long would it take earth to become dark? a) Using the formula d = s x t , where d=distance , s= speed, and t = time, rearrange the terms to solve for time. b) Given the distance to the Sun is 93 million miles ( 1.5 x 10^11 m) and the speed of light is c= 3 x 10^8 m/s) use this information to find out how many SECONDS it takes light to reach earth. c) Convert your answer for b) to Minutes and remaining seconds.arrow_forwardYou are elected as the chief engineer of a project to explore the whole Solar System. Your aim is to design, manufacture and run a satellite -or- a device -or- a spaceship -or- "something" that will travel to each planet in the solar system, explore it and then send the data gained back to Earth. What points you consider as important stages of the project? What kind of travel method(s) you would use to cover whole solar system? How are you going to send back the data you gathered during the exploration?arrow_forward

In your dream, you leave Kala- mazoo at 9 a.m. on a tour along 194: you drive to Chicago, Milwaukee, Minneapolis, and Fargo. You arrive to Fargo at 8 p.m. You spent your entire trip staring out the window enjoying the sights, and (this is a dream, remember?) you didn't get hurt. According to the trip counter on your odometer, you have travelled 813 miles on your trip. The speed limit was between 55 mph and 70 mph on your trip. Were you ever speeding?

- Kepler’s First Law: Elliptical Planetary Orbits: The solar system major planet in the most elliptical solar orbit is little Mercury, which is the closest planet to the Sun. At Perihelion, Mercury’s distance from the Sun (Rp) is 0.31 AU. At Aphelion, Mercury’s distance from the Sun (Ra) is 0.47 AU. The intensity of Sunlight (I) that a planet receives from the Sun is inversely proportional to the square of that planet’s distance from the Sun (R). in other words, I = Constant / R2. Calculate how much more intense the Sunlight received by Mercury is at perihelion (p) than at aphelion (a): Rp2 = Ra2 = Ip / Ia = Ra2 / Rp2 =arrow_forwardWhat will you notice as you fly over the surface of Venus?arrow_forwardWhat is the latitude of the North Pole?
