During the launch of shenzhou-9 spacecraft, it was affected by the buoyancy of the air____ If the density becomes smaller according to VG, the buoyancy is zero During the launch of shenzhou-9 spacecraft, it was affected by the buoyancy of the air____ If the density becomes smaller and the buoyancy becomes smaller according to VG, but according to f = g, it should be unchanged,

You don't understand that buoyancy is equal to the gravity of water or air. It's the gravity of matter. It's the gravity of V, not the gravity of the object itself

The volume of the airship is 2000m and its dead weight is 4900n. When it is launched, what is the buoyancy of the airship in the air? What is the maximum load of the airship?
(air density = 1.29kg/m & # 179;, g = 9.8n/kg)

The density of air is 1.29Kg, m-179;
M exhaust air = 1.29 * 2000 = 2580kg
2580kg*9.8=25284N
G = F-G=
25284N-4900N=20384N
If G is calculated as 10.0,
2580kg*10=25800N
25800N-4900N=20900N
Enthusiastic netizens are right

The volume of airship is 2000 m3 & nbsp; and the deadweight is 4900 n. what is the maximum deadweight of airship when it is launched? (ρ air = 1.29kg/m3)

The buoyancy of this airship in the air is f floating = ρ GV row = 1.29kg/m3 × 9.8n/kg × 2000m3 = 25284n. ∵ f floating = g airship + G object, ∵ the maximum weight that this airship can lift is: G object = f floating-g airship = 25284n-4900n = 20384n. A: the maximum load is 20384n
