How Does Weight Influence Net Force on a Submarine?

AI Thread Summary
The weight of the submarine, which is 14,170 N (calculated from its mass of 1450 kg), is included in the net force acting on it. The net force is determined by the difference between the upward buoyant force of 16,140 N and the combined downward forces, including the weight and the resistive force of 1,030 N. The resistive force arises from friction between the submarine and seawater. Understanding these forces is crucial for analyzing the submarine's movement. Therefore, both weight and resistive forces play significant roles in calculating the net force on the submarine.

A 1450 kg submarine rises straight up toward the surface. Seawater exerts both an upward buoyant force of 16,140 N on the submarine and a downward resistive force of 1030 N.My question: Is the weight of the submarine included in the net force? If the weight is taken into account, is it included in the restive force? If weight is not included in the net force, why not?

Yes the weight would be included in the net force. The resistive force is due to the friction between the water and the submarine.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
