A particle is subjected to the action of two forces: F1 = - 4 i + 7 j + 7 k [kN] and F2 = 9 i - 6 j - 5 k [kN]. The coordinate direction angle of the resultant force with the Z-axis is:

Select one:
a. γR= 68.58°
b. γR= 42.09°
c. γR= 111.42°
d. γR= 24.09°

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

the results is a decrease in air temperature with an increase of altitude.
