1-36. Someone  says  that  it  is  very  humid  outside (high   relative   humidity).   What   does   this statement imply? 1. It is very hot out 2. Precipitation will occur 3. Water vapor content is diminished 4. The air is very moist 1-37. To determine the degree of saturation of the air, you must compute 1. absolute humidity 2. specific humidity 3. relative humidity 4. mixing ratio 1-38. In a given mass of dry air, the ratio of the mass of water vapor to the given mass of dry air is expressed  in  grams  per  gram  or  grams  per kilogram and is known as the 1. mixing ratio 2. specific humidity 3. saturation mixing ratio 4. relative humidity 1-39. Under which of the following conditions will the    specific    humidity    of    unsaturated    air change? 1. Temperature changes 2. Pressure changes 3. Air is compressed 4. Water vapor content changes 1-40. Knowing that the mixing ratio of a parcel of air is 6.3 g/kg and the saturation mixing ratio is 9.0 g/kg,   what   is   the   relative   humidity   of   the parcel? 1. 56 % 2. 63 % 3. 70 % 4. 90 % 1-41. Which of the following statements concerning dew point is most correct? 1. Saturation only occurs if the air temperature is cooled to its dew point 2. Saturation only occurs if the air temperature is increased to its dew point 3. Saturation occurs if the air temperature is cooled   to   its   dew   point   and   there   are corresponding changes in the pressure and water vapor content 4. Saturation occurs if the air temperature is cooled  to  its  dew  point  and  the  pressure and water vapor content do not change 1-42. A   tropical   depression   moved   360   nautical miles in 24 hours. This movement is referred to as 1. acceleration 2. speed 3. velocity 4. inertia 1-43. A  low-pressure  center  is  stationary  over  the south  central  North  Atlantic  Ocean  for  three days.  On  day  four,  the  low  moves  250  miles north. Which law of motion applies to the low’s change in position? 1. Newton’s first law 2. Newton’s second law 3. Newton’s third law 4. Dalton’s law 1-44. A  stationary  high-pressure  center  begins  to move,  and  in  12  hours,  the  upper-level  winds move   the   center   60   nautical   miles.   What property   did   the   high   exhibit   when   it   was stationary, and what was necessary to move it 60 nautical miles? 1. Acceleration and inertia 2. Inertia and acceleration 3. Inertia and work 4. Kinetic energy and potential energy 1-45. A destroyer is dead in the water. Which of the following forces is NOT acting upon the ship? 1. Gravity 2. A contact force 3. An at-a-distance force 4. A resultant force 4
