Calculating If the average or normal temperature decrease with altitude in the troposphere is 6.5°C/km, calculate the approximate altitude in which a pilot would expect to find each of the following atmospheric temperatures, if the surface temperature is 27°C. Show your work. 10°C: 0°C: meters meters

- The temperature of 10°C will be experienced at an altitude of 2.52 km

- The temperature of 0°C will be experienced at an altitude of 4.15 km

Explanation:

Lapse Rate = -6.5°C/km of ascent.

Lapse Rate = Temperature difference/altitude difference

For the 10°C,

Temperature difference = 10 - 27 = -17°C

-6.5 = -17/(difference in altitude between the two points)

Difference in altitude = 17/6.5 = 2.52 km

For 0°C,

Temperature difference = 0 - 27 = - 27°C

-6.5 = -27/(difference in altitude between the two points)

Altitude difference = 27/6.5 = 4.15 km

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
