Answer:
995 N
Explanation:
Weight of surface, w= 4000N
Gravitational constant, g, is taken as 9.81 hence mass, m of surface is W/g where W is weight of surface
m= 4000/9.81= 407.7472
Using radius of orbit of 6371km
The force of gravity of satellite in its orbit, 
Where
and 

F= 995.01142 then rounded off
F=995N
The pressure drop in pascal is 3.824*10^4 Pascals.
To find the answer, we need to know about the Poiseuille's formula.
<h3>
How to find the pressure drop in pascal?</h3>
- We have the Poiseuille's formula,

where, Q is the rate of flow, P is the pressure drop, r is the radius of the pipe,
is the coefficient of viscosity (0.95Pas-s for Glycerin) and l being the length of the tube.

- Thus, the pressure drop will be,

Thus, we can conclude that, the pressure drop in pascal is 3.824*10^4 Pascals.

Answer:
The pulling force F is 200 N
Explanation:
We note that the tension in a rope between two or three blocks is given by the relation;
Where we have;
m₁ → T₁ → m₂ → T₂ → m₃ → F


m₁ = 2 kg
m₂ = 4 kg
m₃ = 4 kg
T₂ = 120 N
Therefore, by substitution, gives;
2 kg → T₁ → 4 kg → 120 N → 4 kg → F

F = 120 N × (10 kg)/(6 kg) = 200 N
The pulling force F = 200 N.
