Question

a bird of mass 1 23 kg is able to hover by imparting a downward
velocity 10m/s2 uniformly into the air of density P kg/m3 over an
effective area 0 1m2 If the accerelation due to gravity is
19m/s2,then the magnittof P in kg/m2
a 0 0123
b 0 123
c 1 23
d 1 32

Sai Rupesh · Answer

Density=mass/volume
1 23/a*p=1 23/0 1*10=1 23kg

a bird of mass 1.23 kg is able to hover by imparting a downward velocity 10m/s2 uniformly into the air of density P kg/m3 over an effective area 0.1m2 .If the accerelation due to gravity is 19m/s2,then the magnittof P in kg/m2 a 0.0123 b 0.123 c 1.23 d 1.32
