Answer:
Since their wings and body develop the drag. When there is warm air then they expand their wings. Since,soaring birds and glider pilots have no engine, they always maintain their high speed to lift their weight in air for hours without expending power by convection
Explanation:
Answer:
(a)-0.701m
(b)-0.674m/s
Explanation:
Given a = -0.24,m/s² Xo = 0.170m, u = 0.190m/s
X = Xo + ut +1/2at²
X = 0.170 + 0.190×3.6 + 1/2×(-0.24) 3.6² = -0.701m
(b) its velocity at the end of this time interval is v
v = u + at
= 0.190 + (-0.24)× 3.6 = -0.674m/s

Explanation:
For rotational equilibrium of the door we can say that torque due to weight of the door must be counter balanced by the torque of external force

here weight will act at mid point of door so its distance is half of the total distance where force is applied
here we know that

now we will have


so our applied force is 72.5 N
