A) 0.0123
B) 0.123
C) 1.23
D) 1.32
Correct Answer: C
Solution :
Given: Mass of bird m = 1.25 kg Velocity v =10m/s Area, \[A=0.1\,{{m}^{2}}\] The density is given by \[\rho =\frac{Mass}{Volume}=\frac{M}{V}=\frac{M}{Av}\] \[(\because V=Av)\] \[=\frac{12.3}{0.1\times 10}=1.23\,kg/{{m}^{3}}\]You need to login to perform this action.
