1)During a mountain climbing trip it is observed that the water used to cook a meal boils at 93 °C rather than the standard 100 °C at sea level. At what altitude are the climbers preparing their meal? (See Physical Properties of Water (SI Units) and Properties of the U.S. Standard Atmosphere (SI Units) for data needed to solve this 2)The following bearings taken on a closed compass and fill up the table. Lines Bearings (deg-min) Azimuth N Deflection Angles...
1) An observer fails to check the bubble of a level and it is off two divisions on a 100-m sight. If the sensitivity of the bubble is 20-sec, what error would there be in the reading? 2 ) The following azimuths are from the north: 329°20’, 180°35’, 48°32’, 170°30’, 145°25’, 319°35’, 350°45’, 95°49’, 11°30’, 235°45’. Express these directions as (a) azimuth from the south, (b) back azimuths, (c) bearings. 8) 6.7 The following azimuths are reckoned from the north:...
