As mentioned on page 13, the MCO was lost because of a mix-up in the units used to calculate the force needed to correct its trajectory. Ground-based computers generated the forte correction file. On September 29, 1999, it was discovered that the fortes reported by the ground-based use in MCOnavigation software were by a factor of 4.45. The erroneous trajectory brought MCO 56 km above thesurface of Mars: the correct trajectory would have brought the MCO approximately 250 km above the surface. At 250 km, the NCO would have successfully entered the desired elliptic orbit. The data contained in the force correction files were delivered in lb-sec instead of the required Sl units of newton-sec for the MCO navigation software. The newton is the SI unit of force is described in Appendix B. The British Engineering (gravitational) system uses a pound (b) as a unit of force and ft / s2 as a unit of acceleration. In turn. the pound is defined as the of on unit of mass at a caused by gravity 32.174ft / s2. The unit of mass this is the slug, which is 14.59 kg. Thus,

- Marie Curie was born in Poland but studied and carried out her research in Paris. In 1903, she shared the Nobel Prize in Physics with H. Becquerel and her husband Pierre for their discovery of radioactivity. (In 1911 she received the Nobel Prize in Chemistry for the discovery of two new chemical elements, radium and polonium, the latter named for her homeland, Poland.) They and others observed that a radioactive substance could emit three types of radiation: alpha (), beta (), and gamma (). If the radiation from a radioactive source is passed between electrically charged plates, some particles are attached to the positive plate, some to the negative plate, and others feel no attraction. Which particles are positively charged, which are negatively charged, and which have no charge? Of the two charged particles, which has the most mass? Radioactivity. Alpha (), beta I(), and gamma () rays from a radioactive element are separated by passing them between electrically charged plates.arrow_forwardA east.cengagenow.com OWLV2 | Online te in Course: CHM_103_003 General Chemistry I [References] Use the References to access important values if needed for this question. 8A 1A H 2A 4A 5A 6A 7A He 3A Be BCNOF Ne Mg 1B 28 A1 Si PS CI Ar 3B 4B 5B 68 7E E 8B K Ca Sc Tiv Cr Mn Fe Co Ni Cu Zn Ga Ge As Se Br Kr Rb Sr Y Zr Nb Mo Tc Ru Rh Pd Ag cd In Sn Sb Te I Xe Cs Ba La Hr Ta Hg TI Pb Bi Po At Rn Fr Ra Ac RT Ha et Er Tm Yb Lu ot Fm Md No Lr ot (1) What is the name of the element with a valence electron configuration of 3s2?
