- What is the difference between tidal volume and vital capacity? Suggest a way you could measure a person’s tidal volume.Question: The current and most scientifically accurate theory for the formation of the Moon is: a.) The large impact theory. b.) The capture theory. c.) The fission theory. d.) The twin formation theory.3. Several years ago, NASA conducted the Lunar CRater Observation and Sensing Satellite (LCROSS) mission to look for evidence of water deep in craters near the south pole of the Moon (www.nasa.gov/mission_pages/LCROSS/main/index.html). Preliminary analysis of the LCROSS data has already demonstrated that there are indeed signifcant quantities of water on the Moon-a useful thing to know if we ever decide to build a permanent base on the Moon. The LCROSS spacecraft was launched from Earth aboard at Atlas V rocket on 18 June 2009. It was then sent on its way to the Moon by a Centaur transfer stage rocket. On 9 October 2009, while being observed by the LCROSS spacecraft, the Centaur rocket crashed into a crater at the south pole of the Moon creating a huge plume of Lunar dust. Instruments on the LCROSS spacecraft measured the spectroscopic properties of this dust and radioed this data back to Earth for analysis. Then, 4 minutes after the Centaur rocket impacted the Moon, the LCROSS…
- 7) Calculate the gravitational field strength (g) on the surface of Jupiter.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,…21) Why doesn't Venus have as many craters as Earth's moon?
