Identify the object in the solar system.
Answer to Problem 1RQ
The object described here is a meteoroid.
Explanation of Solution
A meteoroid is nothing but is a piece of stone debris move through the space. This may have found in large or smaller size. Some of the smallest meteoroid comes from the moon or mars and largest meteoroid assumed to be comes from the asteroid belt. Meteoroids also will come to the earth’s atmosphere and it will start to glow because of the attrition.
Meteoroids can also make big impact on the planets as well as different moon surfaces. Most of the meteoroids are larger than a pebble and are rocky. These are also the part of Solar system. When these are enter into the earth’s atmosphere and some part is survived form the friction, the leftover part is known as meteorite.
Conclusion:
Therefore, the object described here is a meteoroid.

- Since 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?arrow_forwardWhile looking through the Mt. Palomar telescope, you discover a large planetary object orbited by a single moon. The moon orbits the planet every 7.35 hours with the centers of the two objects separated by a distance roughly 2.25 times the radius of the planet. Fellow scientists speculate that the planet is made of mostly iron. In fact, the media has dubbed it the ''Iron Planet'' and NASA has even named it Planet Hephaestus after the Greek god of iron. But you have your doubts. Assuming the planet is spherical and the orbit circular, calculate the density of Planet Hephaestus.arrow_forwardWhat is the gravity of Mars, if the mass of the planet is 6.39x1023kg and the radius of the planet is 3397.2 km?

- A)At what altitude would a geostationary sattelite need to be above the surface of Mars? Assume the mass of Mars is 6.39 x 1023 kg, the length of a martian solar day is 24 hours 39minutes 35seconds, the length of the sidereal day is 24hours 37minutes 22seconds, and the equatorial radius is 3396 km. The answer can be calculated using Newton's verison of Kepler's third law.arrow_forwardYou are a rover pilot on the crew of the initial exploration team sent to Kepler 22b,the first extrasolar planet discovered within the habitable zone of a sun-like star. Thescience team recently discovered liquid water on the surface. (Hurrah!) Your rover isat point A on the shore of a circular lake with radius 4 km collecting samples. Thescience team wants to send your rover to a point C diametrically opposite A. Therover can drive around the circumference of the lake at a rate of 4 km per hour andfly over the lake at a rate of 3 km per hour.(a) How long will it take the rover to fly across the lake?(b) How long will it take the rover to drive around the shore of the lake?You could also fly at an angle θ along a chord inside the circular lake, andcomplete the rest of the path driving along the circumference of the lake.(c) Find the length of the chord in terms of θ. How long will it take the drone totraverse the chord?(d) Find the length of the remaining shoreline after the cord in…arrow_forwardJupiter's moon Io has active volcanoes (in fact, it is the most volcanically active body in the solar system) that eject material as high as 500 kmkm (or even higher) above the surface. Io has a mass of 8.93×10^22kg and a radius of 1821 km. How high would this material go on earth if it were ejected with the same speed as on Io?

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?

- The figure shows, not to scale, a cross section through the interior of Earth. Rather than being uniform throughout, Earth is divided into three zones: an outer crust, a mantle, and an inner core. The dimensions of these zones and the masses contained within them are shown on the figure. Earth has a total mass of 5.98 x 1024 kg and a radius of 6370 km. Ignore rotation and assume that Earth is spherical. (a) Calculate ag at the surface. (b) Suppose that a bore hole (the Mohole) is driven to the crust-mantle interface at a depth of 25.0 km; what would be the value of ag at the bottom of the hole? (c) Suppose that Earth were a uniform sphere with the same total mass and size. What would be the value of ag at a depth of 25.0 km? (Precise measurements of ag are sensitive probes of the interior structure of Earth, although results can be clouded by local variations in mass distribution.) 6345 km (a) Number (b) Number 25 km Number i 3490 km -Core, 1.93 x 1024 kg Mantle, 4.01 × 1024 kg Crust,…arrow_forwardThe mass of venus is 4.883x10^15 Tg and density of Venus is 5.256 g/cm^3.
