How far does the satellite travel in one hour? Assume that the radius of Earth is 4,000 miles. What is the greatest distance on the surface of the earth that can be seen from the top of a mountain which is 2.4 km hi...
Volume and Mass of Sphere: Firstly, the value of the volume of the given metal sphere is computed by the formula shown below: {eq}\displaystyle V=\frac{4}{3}\pi r^3 {/eq}, where, {eq}r {/eq} is the radius of the sphere in centimeters....
Observations of the surface of Mercury reveal many dozens of fault escarpments that record an episode of global contraction early in the planet's history. There is no evidence for global expansion. Homogeneous accretion models for Mercury involving heating and core formation predict significant global...
Mercury, SurfaceMercury, InteriorPlanetary dynamicsMapping tectonic features using MESSENGER data mainly acquired at high Sun incidence angle (>50°) reveals previously undetected structures. The analysis of the latter features determines an upward revision of measurements of density and spatial distribution...
Using the inverse square law, estimates can be made of the distances at which illumination from a light-trap is equal to that from background sources. From these distances an index of trap radius can be constructed which can be considered as a measure of trap potential. Between new moon and...
A particle that is moving in circular motion is subjected to a force referred to as centripetal force. This force is called the center seeking force because the direction of the acceleration is towards the center of the motion. The centripetal force is proportional to t...
The Michelson Doppler Imager (MDI) aboard the Solar and Heliospheric Observatory observed the transits of Mercury on 2003 May 7 and 2006 November 8. Contact times between Mercury and the solar limb have been used since the seventeenth century to derive the Sun's size but this is the first ...

Analysis of images obtained by the MESSENGER spacecraft during its three flybys of Mercury yields a new estimate for the planet's mean radius of 2439.25卤0.69 km, in agreement with results from Mariner 10 and Earth-based observations, as well as with MESSENGER altimeter and occultation data. ...
Mercury in the Arctic originates from emissions and releases at lower latitudes and, to a lesser extent, from local and regional sources. The relationship between mercury (Hg) and polycyclic aromatic hydrocarbons (PAHs) in sediment can be applied as an indicator of the mercury source. This ...
